CHANGES FOR VERSION 5.53.0 (as compared to 5.52.0)

1. Triangle drawing tool now supports filled interiors
2. Vertical selector line was flicerking with RT update when more than one chart window was open. Fixed
3. SetChartGradientFill renamed to SetGradientFill
4. SetGradientFill now has 2 more arguments: baseline and baselinecolor. Allows reverse gradient chart (such as underwater equity) and 3 color gradients top->baseline->bottom
5. Added 2-year and 5-year x grid spacing
6. Gradient chart sometimes disappeared when null values were in the data set and chart was zoomed out to the maximum. Fixed.
7. GUI: Preferences dialog adjustments (moved "bold" checkbox in color page, removed obsolete "show vertical line" boxes in charting page, moved candlestick outline color settings from charting to color page )
8. styleClipMinMax interferred with styleGradient in 5.52.0. Fixed (both styles can now be used independently as well as combined together)

CHANGES FOR VERSION 5.52.0 (as compared to 5.51.1)

1. Chart themes implemented, featuring new look, new grid settings, new background gradient fills, predefined themes for more details see: http://www.amibroker.com/guide/h_themes.html
2. Charts: X-axis algorithm rewritten (now it is clearer and prevents overcrowded/unreadable X labels)
3. Charts: added native gradient area charts. Gradient chart is obtained using styleGradient. Upper gradient color is specified by color parameter in Plot() function, bottom gradient color is either background color or can be defined using SetChartGradientFill function. styleGradient can be combined with styleLine
4. Charts: Plot/PlotForeign/PlotOHLC now adds extra parameter "width" that controls the width of the line. Positive values specify PIXEL width, negative values specify width in percent of current bar width.
5. Eliminated build-up of rendering times caused by growing of MFC temporary GDI object maps in non-UI threads. Now rendering engine uses direct WINAPI calls without MFC
6. View->Filtering menu was disabled in 5.51.x. Fixed
7. Data window was not working in 5.51.x. Fixed
8. " Show middle lines" = "NO" causes date axis to be moved down outside visible area. Fixed.
9. Selector line was not working correctly in 5.51. Fixed.
10. Bold dotted trendline did not work in 5.51 BETA. Fixed
11. AFL: LinearReg/LinRegSlope/LinRegIntercept/TSF/StdError display proper error message when user passes negative (wrong) parameter
12. Study tooltip information now includes also number of bars between start and end of the trendline
13. New Analysis: saving last column layout works better
14. Account manager: Edit->Undo menu was missing. Fixed.
15. GetFnData() now supports retrieving "Address" field too
16. On Win98 and above drawing engine uses DC_PEN/DC_BRUSH for speed
17. Optimize() reduced possibility of IEEE floating point accumulation errors with steps PlotShapes() does not plot multiple times in same x/y pos anymore - it results in faster rendering when shapes overlap (large zoom outs)

CHANGES FOR VERSION 5.51.2 (as compared to 5.51.1)

1. PlotShapes() rendering was slower in 5.51 than in 5.50. Fixed.
2. Interpretation was blank with new rendering engine. Fixed.
3. Charts: Quick AFL was disabled in new rendering engine causing slowdowns with > 100K bars. Fixed

CHANGES FOR VERSION 5.51.1 (as compared to 5.51.0)

1. fix for low-level Gfx* functions causing crash when multithreaded GDI was enabled

CHANGES FOR VERSION 5.51.0 (as compared to 5.50.5)

1. Charts: Multithreaded GDI chart rendering implemented for super-smooth UI response and preventing GDI-intensive charts from detoriating entire UI responsiveness
2. Maximum rendering time limit increased to 1000ms (1sec) when multithreaded charts + GDI are enabled (allowing 2 times more complex plots without Warning 901)
3. 64-bit only: brand new eSignal 64-bit plugin (3.0.0BETA)

KNOWN ISSUES:

1. None.

A new version of AmiQuote 3.03 is available for download from

http://www.amibroker.com/bin/aq3030.exe (100KB) - 32 bit version

This version features a brand new Intraday (1-minute and 5-minute bars) backfill data from Yahoo Finance and Google Finance
Yahoo Intraday and Google Intraday include all US stock markets and some international markets covered by Yahoo Finance.
Normally you receive 15-minute delayed data. The delayed intraday data from Yahoo Finance and from Google Finance are free (no subscription necessary).

If you, however, have Yahoo RT subscription and you are logged into your Yahoo Finance account using Internet Explorer and you marked "Allow cookies" option in AmiQuote Tools->Settings then you might get non-delayed intraday data (at your own risk and subject to change as Yahoo may change authentication methods).

If you don't know the symbol, you can use Yahoo Finance symbol lookup:
http://finance.yahoo.com/lookup

Google Intraday Limitations:

1. Only 1-minute and 5-minute intraday bar intervals are supported
2. The backfill covers upto 15 most recent days back for 1-minute bars and upto 60 most recent days back for 5-minute bars
3. Only regular trading session is included
4. You need to be registered user of AmiQuote to use Google Intraday download.
   If you don't have AmiQuote license yet, you can order AmiQuote license from http://www.amibroker.com/order.php - it is only $65 one time fee.

Yahoo Intraday Limitations:

1. Only 1-minute and 5-minute intraday bar intervals are supported
2. The backfill always covers just one most recent day back for 1-minute bars and upto 5 (five) most recent days back for 5-minute bars
3. Only regular trading session is included
4. You need to be registered user of AmiQuote to use Yahoo Intraday download.
   If you don't have AmiQuote license yet, you can order AmiQuote license from http://www.amibroker.com/order.php - it is only $65 one time fee.

The upgrade is free for all previously registered AmiQuote users.

CHANGES FOR VERSION 3.03 (as compared to version 3.02)

1. added "Max days" edit to control maximum intraday backfill length. Specifying lower than maximum allowed days results in faster download and less data to transfer. Google Intraday supports 1..15 max days for 1-minute bars and 1..60 max days for 5-minute bars. Yahoo Intraday supports only 1-day of 1-minute bars and only 1 and 5 days of 5-minute bars. Specifying other combinations (such as 2, 3 or 4 max days for 5-minute bars) for Yahoo results in retrieving all 5 days.

IMPORTANT:

AmiQuote is nothing but specialized web browser/downloader. You are using 3rd party web pages/services (Yahoo/MSN/Google/Finam) available to the public and AmiQuote acts like Internet Explorer or Firefox. The availability of data/web pages depends on those 3rd parties and may change in the future. The financial data downloaded from public web sites such as Yahoo Finance/MSN/Google/Finam are for personal use only. Consult 3rd parties' Terms of Service for details. For actual trading we recommend using paid data sources that provide higher data quality and reliability.

NOTE for AmiBroker 64-bit users:

There is also a 64-bit version of AmiQuote available from http://www.amibroker.com/bin/aq3030x64.exe (120KB) - but please note that if you installed AmiBroker 64-bit to directory different than C:\Program Files\AmiBroker then you would need to pick correct AmiBroker 64-bit installation directory manually, since this small update package would not detect 64-bit AmiBroker installation automatically.

CHANGES FOR VERSION 5.50.4 (as compared to 5.50.3)

1. New Analysis: "Show arrows for actual trades" sometimes used date range from old AA. Fixed
2. New Analysis: Individual backtest - custom metrics columns would not appear if very first symbol under test does not generate ANY trades. Fixed.
3. UI: when you float a maximized MDI window it becomes little smaller so it does not overlap MDI tabs.
4. Print/Print Preview: circle/arc/rectangle objects outside current view are properly clipped on printouts
5. New Analysis: When user cancelled optimization in the middle and ran backtest afterwards then this single follow up backtest could be incorrect and required another run to produce correct result again. Fixed.
6. When timeshift != 0 then duplicate range markers could appear at day boundary. Fixed.
7. Small rounding issue in ray drawing fixed
8. When multiple chart panes were using SetForeign on rare occassions foreign call could fail (return other symbol data) Fixed.

CHANGES FOR VERSION 5.50.3 (as compared to 5.50.2)

1. Blank chart can be closed using flyout minitoolbar now
2. Fixed crash @7C8097FF when trying to drag drop indicator on chart when database is empty
3. Formulas: Ichimoku cloud added
4. Formulas: faster version of Portfolio Equity formula
5. Formulas: styleNoLabel is now default for all "Band" formulas (Bollinger/Keltner/Percent)

9. PlotVAPOverlay did not draw the very last level line. Fixed. Also done some cosmetic tweaks.

12. When database is empty or chart does not have properly selected symbol the information note is displayed in the chart window (instead of blank chart)
13. When settlement delay was set to zero, then interest rate setting was ignored (5.46-5.50.2). Fixed.

CHANGES FOR VERSION 5.50.2 (as compared to 5.50.1)

1. New Analysis and Old AA: HoldMinBars > 0 can now be used together with AllowSameBarExit=True
2. New Analysis: SeparateLongShortRank required proper MaxLongPos and MaxShortPos definitions in order to work. Now if they are missing defaults are applied as in old AA.
3. New Analysis: If current formula is open in the formula editor it is auto-saved prior to running any Analysis (as old AA did)
4. New Analysis: on attempt to load analysis project file that contains formula path that does not exist or is not writable AmiBroker will create the formula in the "Formulas\Imported" folder instead of not creating it at all
5. New Analysis: on Backtest/Optimization current formula is saved in @LastBacktestFormula registry key so it can be referenced by Individual Equity formula
6. New Analysis: when formula is picked from the folder that is inside current working directory, then relative path is used and stored in project instead of absolute path previously used
7. New Analysis: WinXP-only - RMB click column descend/ascend menus were not working due to Windows XP bug. Fixed.

9. Plugins: IQFeed: added "You can't close plugin window" on attempt to close working IQFeed window.
   Settings: 'Stops' tab: N Bar stop has priority check box state was not saved. Fixed

12. UI: Floating non-chart windows (account/web browser/analysis) are not closed when switching layouts.

CHANGES FOR VERSION 5.50.1 (as compared to 5.50.0)

12. GetFnData() supports new field "Alias" - return Alias field without need to use OLE
13. GetOption supports new fields: ApplyTo and Filter*, eliminates the need to use OLE for that purpose
14. Fix for FPU inaccurracies in range bars implemented

16. New Analysis: Column customization/state persistence implemented
17. Charts: New Y axis grid algorithm for clearer display on condensed charts
18. AFL: CategoryGetSymbols supports new categoryAll (all symbols in the database) and new Mode parameter

20. AFL: Added ThreadSleep( milliseconds ) function. It suspends current thread for specified number of milliseconds (maximum is 100 ms). Works only from NON-UI threads. When called from UI thread the function does NOTHING and returns immediatelly. Please do NOT abuse this function. Using it may negatively impact performance.
21. AFL: Added StaticVarCompareExchange function. Provides atomic interlocked compare/exchange functionality

CHANGES FOR VERSION 5.49.2 (as compared to 5.49.1)

1. New Analysis: added Optimize->3D Optimzation chart menu
2. New Analysis: buttons for Portfolio Equity/Individual Equity charts added
3. New Analysis: Info Bar added (that duplicates some of the info that normally appears on the Info Tab). It can be turned on using Settings->Info Bar
4. New Analysis: Report generation is now OFF by default when running optimization/walk forward as in old AA. This gives about 0.9 sec gain per step.
5. New Analysis: Single-symbol optimization made faster by caching already compressed quote array on subsequent steps
6. New Analysis: the check for Status("StockNum") was sensitive to blanks between parenthesis, function name and string parameter. Now it is made insensitive to blanks.
7. New Analysis: when "Range" was "n last bars" or "n last days", Status("rangefromdate") gave date of preceding bar. Fixed.
8. UI: "Performance" tooltip title was not always updated on time. Fixed.
9. UI: "Wait for plugin" window displays progress bar with "marquee" style instead of circle of dots

CHANGES FOR VERSION 5.49.1 (as compared to 5.49.0)>

1. New Analysis: "Backtest started", "Exploration started" text in the info tab appeared twice per run (instead of once). Fixed

3. New Analysis: Fixed crash that could occur when running analysis with Range set to "N recent bars" and N was exceeding number of quotes.
4. New Analysis: Float/Normal/Close popup menu RMB menu was active everywhere in floating window instead of only caption area. Fixed.
5. New Analysis: Implement single-thread start when Status("StockNum") is detected in the code. Other threads are started when first symbol processing is completed.
6. New Analysis: Send to Analysis did not update formula combo box properly in certain scenarios: when formula X was selected, then formula Y, then formula X again. Fixed.
7. New Analysis: Testing on unaligned data sometimes took longer than expected because of the work necessary to bring signals in order. Now a smart method avoids most of the memory transfers and can give 10x speedup on backtesting very long unaligned intraday data.
8. Old AA: status bar displays true timing for fair comparisons between old AA and new Analysis. Watching progress bar numbers was misleading as it closed before all processing was truly complete, so it looked like old AA completed sooner than it really did
9. UI: menu item for Old Automatic Analysis restored as apparently some users got lost. Also attempt to run old Automatic analysis displays an information about new Analysis window

CHANGES FOR VERSION 5.49.0 (as compared to 5.48.0)

10. UI: Data window scroll bars are hidden and do not flicker when updating
11. UI: Adjusted item Y offset for owner drawn listviews for consitent look with old layout of system listviews in Windows XP and earlier OSes
12. UI: Account, Analysis and Web research windows don't use client edge/border anymore - gives slicker / less crowded look
13. UI: "Save All" toolbar button removed, "Save database" button added to replace it
    QuoteEngine: Range bars algorithm improved significantly
14. Quote array uses 20480 bytes (512 quotes) allocation chunk size (exactly 5x4KB page) now
15. New Analysis: when floating pane is made normal from/to dates were reset to today. Fixed.
16. New Analysis: when Apply To: Filter is defined so NO symbol matches the criteria, appropriate message is displayed when trying to run Analysis and action is terminated instead of displaying progress bar forever
17. New Analysis: when analysis window is "floating" double click/show arrows/sync affects active MDI chart just like old AA did, as opposed to last one (when analysis is not floating)

19. New Analysis: implemented import / export, File menu now has Import HTML and Export HTML/CSV commands
20. New Analysis: Implemented "Wait for backfill" option. This slows down analysis sequence so AmiBroker waits for external RT data source to deliver backfill data
21. New Analysis: Custom backtester uses "last backtest settings" when calling GetStatus() instead of old AA settings
22. New Analysis: auto-repeat interval edit field did not allow to enter values if moved to main toolbar via customization. Fixed.
23. Formula Editor Analysis toolbar button now operates on New Analysis window
24. Default for timestamping of intraday compression changed to "Show START time of interval"
25. Charts: Tooltips automatically display also OHL prices (in addition to close) when Plot style is set to candlestick, bar or when PlotOHLC was used
26. Charts: AFL error message color is now definable in Tools->Preferences, "Color" tab

CHANGES FOR VERSION 5.48.0 (as compared to 5.47.0)

1. New Analysis: custom metrics columns were invisible in backtest/optimizations. Fixed. (#91031)
2. New Analysis: backtest did not display proper column names when Report mode was different than trade list. Fixed. Also added support for changing report mode via SetOption().
3. New Analysis: Auto-repeat Scan/Explore implemented (aka. "Run every" in old AA) (use drop down menu next to "Settings" button)
4. New Analysis: Showing arrows by double click implemented
5. New Analysis: Sync chart on select option implemented (use drop down menu next to "Settings" button)
6. Fixed window activation issue after RMB click in chart window when non-chart floating windows are active

11. New Analysis: Fixed problem with opt steps warning dialog appearing sometimes in the out-of-sample tests in walk forward sequence
12. New Analysis: Signal heaps are separated now, allowing to run concurrent backtest/optimizations in many analysis windows
13. New Analysis: removed unnecessary refreshes of symbol list during optimizations that caused slowdowns when user had large database
14. New Analysis: The size of control fields is properly adjusted with regards to DPI
15. New Analysis: Status("StockNum") was always zero in 5.47 and earlier. Now it is set properly.
16. Fixed Error 53 message that was giving an error when proper \" (quotation mark espace sequence) was used

CHANGES FOR VERSION 5.47.0 (as compared to 5.46.0)

1. New Analysis: implemented Walk-Forward testing (use drop arrow next to Optimization button)
2. New Analysis: last used ApplyTo/Range/From/to dates/filters and other settings are saved when Analysis window is closed
3. Fibonacci retracement- modifying Z-order affected only control trendline, not all lines as it should. Fixed.
4. Default title for new analysis window is "AnalysisX" (instead of "Unnamed") where X is consecutive number 1, 2..
5. attempt to use Say() on computer without sound card or without driver installed does not result in throwing exception/crash report, but it is rather silently ignored
6. AFL engine: new error 53: incorrect \ espace sequence. Error is issued when user forgets that single slash must be written as \\
7. Fixed "slow response" problems some users reported when switching symbols)

CHANGES FOR VERSION 5.46.0 (as compared to 5.45.0)

1. New Analysis: Exhaustive multi-threaded optimization implemented
2. New Analysis: Smart (non-exhaustive) multi-threaded optimization implemented in a way compatible with existing optimizer plugins
3. Slight modification to the way how compressed bar charts are drawn (so bars with H==L are better visible)

4. New Analysis: Changed alignment of Date/Time column to left in backtest result list.
5. Most AFL engine setup moved to worker threads. Result - smaller UI thread load in MT charts (better scalability) and much faster (upto 2x) explorations/scans in New Analysis window
6. New Analysis: added "Info" tab that provides some summary information about analysis (number of rows, timings, backtest summary) - contents can be copied using Ctrl+C / Edit->Copy
7. New Analysis: first-phase backtest signal processing and ranking moved to non-UI threads, enabling better parallelism, results in better backtest performance (upto 2x in with trivial codes)

CHANGES FOR VERSION 5.44.1 (as compared to 5.44.0)

1. Removed dialog box with partial timings that appeared after backtest in the new analysis window. (It was introduced in 5.44.0 for performance fine-tuning purposes, but not really needed for end-user).

CHANGES FOR VERSION 5.44.0 (as compared to 5.43.1)

1. New Analysis: fixed AddToComposite()
2. New Analysis: Interval() function was working incorrectly in new analysis window. Fixed.
3. New Analysis: Backtest ~~~EQUITY symbol did not have "use only local database" set in 5.43.1. Fixed.
4. New Analysis: Backtest performance improved by removing some unnecessary list view refreshes (now it should never be slower than old AA even with simplest formulas)

CHANGES FOR VERSION 5.43.1 (as compared to 5.43.0)

5. In 5.41.0 did not display Time&Sales in reverse order (newest on top). Fixed.

CHANGES FOR VERSION 5.41.0 (as compared to 5.40.0)

1. New Analysis window (File->New->Analysis) - featuring multithreaded Scan and Exploration
   Performance note: to fully benefit from multithreading it is best to use AmiBroker local NATIVE database (not external) as it is the only database that can deliver data quickly enough. Tests show that on AmiBroker native databases scans and explorations are 100% scalable to multiple cores
   - i.e. for example would run upto 8 times faster on 8 CPU/core machine. IMPORTANT: This window is work-in-progress. Multithreaded Backtest and Optimization features will be added later.
2. Totally rewritten listview with very efficient owner draw code speeds up list view scrolling/resizing/repainting more than 10 times. Native system ListView control is terribly slow on Windows XP/Vista/7 (surprisingly it was many times faster in Win9x!)
3. AFL: AddColumn - added mini bar charts to explorations
4. Mini-chart in RT Quote window. Mini chart shows where LAST price is within LOW-HIGH range.
5. AFL: Percentile() does a param check for range > 0 now
6. Errors and warnings are now displayed in red color in the indicator pane
7. During actual GDI chart rendering AmiBroker measures time and if it exceeds 500ms timeout it stops rendering with Warning 901.
8. Warning 502: Calling Plot()/PlotOHLC over 500 times is displayed in indicator in runtime to prevent abuse
9. All list views, pressing Ctrl and NumPad'+' automatically adjusts column widths to content
10. If data are missing in the in-memory cache, Foreign() calls from non-GUI threads use synchronous retrieval method for reliability.
11. Old and new Analysis window: outputting millions of rows to listview is much faster now
12. All list views - Ctrl+A (Select All) made much faster

1. New Analysis and Old AA: HoldMinBars > 0 can now be used together with AllowSameBarExit=True
2. New Analysis: SeparateLongShortRank required proper MaxLongPos and MaxShortPos definitions in order to work. Now if they are missing defaults are applied as in old AA.
3. New Analysis: If current formula is open in the formula editor it is auto-saved prior to running any Analysis (as old AA did)
4. New Analysis: on attempt to load analysis project file that contains formula path that does not exist or is not writable AmiBroker will create the formula in the "Formulas\Imported" folder instead of not creating it at all
5. New Analysis: on Backtest/Optimization current formula is saved in @LastBacktestFormula registry key so it can be referenced by Individual Equity formula
6. New Analysis: when formula is picked from the folder that is inside current working directory, then relative path is used and stored in project instead of absolute path previously used
7. New Analysis: WinXP-only - RMB click column descend/ascend menus were not working due to Windows XP bug. Fixed.

2. New Analysis: last used ApplyTo/Range/From/to dates/filters and other settings are saved when Analysis window is closed
3. Fibonacci retracement- modifying Z-order affected only control trendline, not all lines as it should. Fixed.
4. Default title for new analysis window is "AnalysisX" (instead of "Unnamed") where X is consecutive number 1, 2..
5. attempt to use Say() on computer without sound card or without driver installed does not result in throwing exception/crash report, but it is rather silently ignored
6. AFL engine: new error 53: incorrect \ espace sequence. Error is issued when user forgets that single slash must be written as \\
7. Fixed "slow response" problems some users reported when switching symbols)

CHANGES FOR VERSION 5.46.0 (as compared to 5.45.0)

1. New Analysis: Exhaustive multi-threaded optimization implemented
2. New Analysis: Smart (non-exhaustive) multi-threaded optimization implemented in a way compatible with existing optimizer plugins
3. Slight modification to the way how compressed bar charts are drawn (so bars with H==L are better visible)

CHANGES FOR VERSION 5.45.0 (as compared to 5.44.1)

1. 64-bit version compiled with new version of C runtime (Microsoft security update)
2. Fixed date/time column sorting in virtual list views when regional date format was different than yyyy-MM-dd
3. AFL: ClipboardSet() returns True (1) when clipboard has been successfully set. Sometimes clipboard is locked by another applications and then write can fail (ClipboardSet() will return zero/False then)
4. New Analysis: Changed alignment of Date/Time column to left in backtest result list.
5. Most AFL engine setup moved to worker threads. Result - smaller UI thread load in MT charts (better scalability) and much faster (upto 2x) explorations/scans in New Analysis window
6. New Analysis: added "Info" tab that provides some summary information about analysis (number of rows, timings, backtest summary) - contents can be copied using Ctrl+C / Edit->Copy
7. New Analysis: first-phase backtest signal processing and ranking moved to non-UI threads, enabling better parallelism, results in better backtest performance (upto 2x in with trivial codes)

CHANGES FOR VERSION 5.44.1 (as compared to 5.44.0)

1. Removed dialog box with partial timings that appeared after backtest in the new analysis window. (It was introduced in 5.44.0 for performance fine-tuning purposes, but not really needed for end-user).

CHANGES FOR VERSION 5.44.0 (as compared to 5.43.1)

1. New Analysis: fixed AddToComposite()
2. New Analysis: Interval() function was working incorrectly in new analysis window. Fixed.
3. New Analysis: Backtest ~~~EQUITY symbol did not have "use only local database" set in 5.43.1. Fixed.
4. New Analysis: Backtest performance improved by removing some unnecessary list view refreshes (now it should never be slower than old AA even with simplest formulas)

CHANGES FOR VERSION 5.43.1 (as compared to 5.43.0)

1. When range different than "All quotes" was selected, backtest in new Analysis window could produce incorrect results in 5.43.0. Fixed.

CHANGES FOR VERSION 5.43.0 (as compared to 5.42.0)

1. New Analysis Window: multi-threaded Backtest feature implemented (experimental)
2. Load/Unload buttons removed from Plugins dialog.
3. ListViews: the last line (partially shown) in RT quote window was not easily selectable. Fixed
4. New Analysis window: Implemented Parameters dialog
5. AFL: GetCursorMouseButtons() sometimes missed clicks when multithreading was on and formula took ages to execute. Now it is now 100% reliable.
6. Auto-selection of proper layer based on selected viewing interval
7. IRA accounts support - implemented Settlement delay in backtester, via SetOption("SettlementDelay", x )
8. Zoom in/out toolbar buttons zoom in finer steps (+/-10%)
9. Analysis ListView, RMB menu new option: "Add Rank column" - adds a column with ordinal rankings based on current sort or just row number column when list is not sorted
10. New feature: Adding new chart/research/account/analysis via (+) tab
11. New Analysis window: Implemented SetSortColumns
12. New Analysis window: Implemented AddSummaryRows

CHANGES FOR VERSION 5.42.0 (as compared to 5.41.0)

1. Implemented right click menu in new Analysis windows (Add symbols to watchlist/Show arrows functionality)
2. Zoom in/out toolbar buttons now have auto-repeat feature
3. In 5.41.0 Ctrl+C from list view copied text without tabs (column separators). Fixed
4. In 5.41.0 did not refresh progress dialog optimization status list. Fixed. (owner draw list view initial size is retrieved in PreSubclass now)
5. In 5.41.0 did not display Time&Sales in reverse order (newest on top). Fixed.

CHANGES FOR VERSION 5.41.0 (as compared to 5.40.0)

1. New Analysis window (File->New->Analysis) - featuring multithreaded Scan and Exploration
   Performance note: to fully benefit from multithreading it is best to use AmiBroker local NATIVE database (not external) as it is the only database that can deliver data quickly enough. Tests show that on AmiBroker native databases scans and explorations are 100% scalable to multiple cores
   - i.e. for example would run upto 8 times faster on 8 CPU/core machine. IMPORTANT: This window is work-in-progress. Multithreaded Backtest and Optimization features will be added later.
2. Totally rewritten listview with very efficient owner draw code speeds up list view scrolling/resizing/repainting more than 10 times. Native system ListView control is terribly slow on Windows XP/Vista/7 (surprisingly it was many times faster in Win9x!)
3. AFL: AddColumn - added mini bar charts to explorations
4. Mini-chart in RT Quote window. Mini chart shows where LAST price is within LOW-HIGH range.
5. AFL: Percentile() does a param check for range > 0 now
6. Errors and warnings are now displayed in red color in the indicator pane
7. During actual GDI chart rendering AmiBroker measures time and if it exceeds 500ms timeout it stops rendering with Warning 901.
8. Warning 502: Calling Plot()/PlotOHLC over 500 times is displayed in indicator in runtime to prevent abuse
9. All list views, pressing Ctrl and NumPad'+' automatically adjusts column widths to content
10. If data are missing in the in-memory cache, Foreign() calls from non-GUI threads use synchronous retrieval method for reliability.
11. Old and new Analysis window: outputting millions of rows to listview is much faster now
12. All list views - Ctrl+A (Select All) made much faster

Comments Off on AmiBroker 5.50.3 Release Candidate 3

Stability: - Release Candidate, pretty stable, should work fine in most environments

This is a RC2 version. Make a backup first

A new Release Candidate 2 version (5.50.2) of AmiBroker has just been released.

32-bit version:
http://www.amibroker.com/bin/AmiBroker550rc2.exe
(9 048 544 bytes)

64-bit version:
http://www.amibroker.com/x64/AmiBroker550rc2x64.exe
(9 359 016 bytes) (update: Jan 9, 2012 - IQFeed plugin 4.0.4 included now)

ATTENTION: This version is free only for users who registered after September 1st, 2009. See Upgrade Policy and Pricing section below for more details.

CHANGES FOR VERSION 5.50.2 (as compared to 5.50.1)

1. New Analysis and Old AA: HoldMinBars > 0 can now be used together with AllowSameBarExit=True
2. New Analysis: SeparateLongShortRank required proper MaxLongPos and MaxShortPos definitions in order to work. Now if they are missing defaults are applied as in old AA.
3. New Analysis: If current formula is open in the formula editor it is auto-saved prior to running any Analysis (as old AA did)
4. New Analysis: on attempt to load analysis project file that contains formula path that does not exist or is not writable AmiBroker will create the formula in the "Formulas\Imported" folder instead of not creating it at all
5. New Analysis: on Backtest/Optimization current formula is saved in @LastBacktestFormula registry key so it can be referenced by Individual Equity formula
6. New Analysis: when formula is picked from the folder that is inside current working directory, then relative path is used and stored in project instead of absolute path previously used
7. New Analysis: WinXP-only - RMB click column descend/ascend menus were not working due to Windows XP bug. Fixed.
8. Plugins: IQFeed plugin uses new faster IQFeed API, downloads less and uses way more efficient method to backfill 1/5/15-second base time intervals. Attention: you need to use new IQClient 4.8.1.7 or higher.
9. Plugins: IQFeed: added "You can't close plugin window" on attempt to close working IQFeed window.
   Settings: 'Stops' tab: N Bar stop has priority check box state was not saved. Fixed
10. UI: Category list now features new icons and decreased indentation
11. UI: Chart tree, Layout tree in "Explorer" theme
12. UI: Floating non-chart windows (account/web browser/analysis) are not closed when switching layouts.
13. UI: Owner-draw listviews now fully implement ellipsis item truncation mechanism, but using ExtTextOut only which is 6 times faster than DrawText that Windows uses

CHANGES FOR VERSION 5.50.1 (as compared to 5.50.0)

1. New Analysis: Individual Backtest implemented. Note that it runs with approx same speed as old AA as Individual Backtest is single threaded for reasons explained in the User's manual.
2. New Analysis: toolbar icons for parameters and settings changed to avoid confusion with the icon for preferences
3. UI: Symbol List uses Windows 7/Vista style
4. New Analysis: Toolbar customization is now saved
5. MRU (most recently used) file menu moved to submenu and MRU list increased to 10 items
6. Charts: fixed small alignment problem on Y axis when using fixed (nonproportional) font
7. New Analysis: backtester object now has EquityArray property that returns entire equity array (not just current value).
8. New Analysis: AddToComposite with atcDeleteValues | atcEnableInPortfolio did not delete previous values. Fixed
9. New Analysis: "Interval" menu item in the auto-repeat group renamed to "AR interval" because some users interpreted it wrong (as periodicity)
10. New Analysis: OLE interface implemented. See http://www.amibroker.com/guide/objects.html for the details.
11. Charts: more tweaks for Y axis algorithm for readability. Now in Tools->Preferences, "Charting" the user may select different grid stepping: Instead of default 1, 2, 5, 10 grid stepping, user may select to use 2.5 step instead of 2 (Use 2.5 step in Y axis)
12. GetFnData() supports new field "Alias" - return Alias field without need to use OLE
13. GetOption supports new fields: ApplyTo and Filter*, eliminates the need to use OLE for that purpose
14. Fix for FPU inaccurracies in range bars implemented

CHANGES FOR VERSION 5.50.0 (as compared to 5.49.2)

1. New Analysis: "Save" creates now a Analysis project (.apx) file that includes all settings and formula needed in single file. The file itself is in human readable XML format
2. UI: File open dialog now has "All supported files" option in the "Files of type"
3. UI: PopupWindow is now resizable (see size gripper in the lower-right corner)
4. AFL: PopupWindow function has additional parameters to control width/height and flag that controls whenever popup window captures input focus
5. New Analysis: ApplyStops applied in non-regular modes are passed to 2nd phase properly now.
6. New Analysis: "Show current trade arrows" fixed.
7. New Analysis: View->Filtering menu options were not available when New Analysis was active. Fixed.
8. New Analysis: Standard Edition has a limit of max 2 threads per Analysis window instance.
9. UI: Log window clicking on error displayed AFL Editor and marked Line+1, Col+1 char position instead of proper place. Fixed
10. New Analysis: Errors are now displayed in a modern message bar instead of dialog box
11. UI: holding down Ctrl and Q keys simultaneously while AmiBroker is starting resets all menus/command bars to defaults
12. New Analysis: scroll bar properly works when "Walk forward" tab is active
13. New Analysis: Walk forward tab content can be now copied using Edit->Copy / Ctrl+C
14. New Analysis: when "wait for backfill" was turned on and external data source was very slow to repond (like IQFeed during backfill) subsequent calls to Status('stocknum') could give non-unique numbers. Fixed.
15. New Analysis: Copy to clipboard includes headers now
16. New Analysis: Column customization/state persistence implemented
17. Charts: New Y axis grid algorithm for clearer display on condensed charts
18. AFL: CategoryGetSymbols supports new categoryAll (all symbols in the database) and new Mode parameter
19. AFL: Added Warning 503. Using OLE / CreateObject / CreateStaticObject is not multi-threading friendly. See Users' Guide ""Efficient use of multithreading"" for more details.
20. AFL: Added ThreadSleep( milliseconds ) function. It suspends current thread for specified number of milliseconds (maximum is 100 ms). Works only from NON-UI threads. When called from UI thread the function does NOTHING and returns immediatelly. Please do NOT abuse this function. Using it may negatively impact performance.
21. AFL: Added StaticVarCompareExchange function. Provides atomic interlocked compare/exchange functionality

CHANGES FOR VERSION 5.49.2 (as compared to 5.49.1)

1. New Analysis: added Optimize->3D Optimzation chart menu
2. New Analysis: buttons for Portfolio Equity/Individual Equity charts added
3. New Analysis: Info Bar added (that duplicates some of the info that normally appears on the Info Tab). It can be turned on using Settings->Info Bar
4. New Analysis: Report generation is now OFF by default when running optimization/walk forward as in old AA. This gives about 0.9 sec gain per step.
5. New Analysis: Single-symbol optimization made faster by caching already compressed quote array on subsequent steps
6. New Analysis: the check for Status("StockNum") was sensitive to blanks between parenthesis, function name and string parameter. Now it is made insensitive to blanks.
7. New Analysis: when "Range" was "n last bars" or "n last days", Status("rangefromdate") gave date of preceding bar. Fixed.
8. UI: "Performance" tooltip title was not always updated on time. Fixed.
9. UI: "Wait for plugin" window displays progress bar with "marquee" style instead of circle of dots

CHANGES FOR VERSION 5.49.1 (as compared to 5.49.0)>

1. New Analysis: "Backtest started", "Exploration started" text in the info tab appeared twice per run (instead of once). Fixed
2. New Analysis: Backtest report did not include formula code. Fixed.
3. New Analysis: Fixed crash that could occur when running analysis with Range set to "N recent bars" and N was exceeding number of quotes.
4. New Analysis: Float/Normal/Close popup menu RMB menu was active everywhere in floating window instead of only caption area. Fixed.
5. New Analysis: Implement single-thread start when Status("StockNum") is detected in the code. Other threads are started when first symbol processing is completed.
6. New Analysis: Send to Analysis did not update formula combo box properly in certain scenarios: when formula X was selected, then formula Y, then formula X again. Fixed.
7. New Analysis: Testing on unaligned data sometimes took longer than expected because of the work necessary to bring signals in order. Now a smart method avoids most of the memory transfers and can give 10x speedup on backtesting very long unaligned intraday data.
8. Old AA: status bar displays true timing for fair comparisons between old AA and new Analysis. Watching progress bar numbers was misleading as it closed before all processing was truly complete, so it looked like old AA completed sooner than it really did
9. UI: menu item for Old Automatic Analysis restored as apparently some users got lost. Also attempt to run old Automatic analysis displays an information about new Analysis window

CHANGES FOR VERSION 5.49.0 (as compared to 5.48.0)

1. Web Research: turned on "silent" mode - should prevent error message boxes displayed by IE engine.
2. UI: when focus is switched to floating document window, the application menu is switched to proper context
3. UI: When File->Close was used on floating pane, document was closed but docking pane was not. Fixed.
4. UI: The toolbar button and menu option to launch old Automatic Analysis window are now hidden (can be brought back by using Tools->Customize), old AA can also be launched from new Analysis via Analysis->Old Analysis menu
5. UI: New menu options and toolbar button to launch new analysis window
6. UI: Moved all menu items controlling visibility of docking windows to "Window" menu
7. UI: floating state of windows can now be turned on/off using right-click menu over tab / floating window caption
8. UI: File->Save (when currently selected window is a chart) command now saves Chart template. To save database use "Save database" instead.
9. UI: Defaults for data window are changed, so extra OHL display is turned off by default as currently PlotOHLC displays all 4 prices in the tooltip and data window already
10. UI: Data window scroll bars are hidden and do not flicker when updating
11. UI: Adjusted item Y offset for owner drawn listviews for consitent look with old layout of system listviews in Windows XP and earlier OSes
12. UI: Account, Analysis and Web research windows don't use client edge/border anymore - gives slicker / less crowded look
13. UI: "Save All" toolbar button removed, "Save database" button added to replace it
    QuoteEngine: Range bars algorithm improved significantly
14. Quote array uses 20480 bytes (512 quotes) allocation chunk size (exactly 5x4KB page) now
15. New Analysis: when floating pane is made normal from/to dates were reset to today. Fixed.
16. New Analysis: when Apply To: Filter is defined so NO symbol matches the criteria, appropriate message is displayed when trying to run Analysis and action is terminated instead of displaying progress bar forever
17. New Analysis: when analysis window is "floating" double click/show arrows/sync affects active MDI chart just like old AA did, as opposed to last one (when analysis is not floating)
18. New Analysis: Optimization parameter setup stage uses now not more than 100 bars. This reduces setup time.
19. New Analysis: implemented import / export, File menu now has Import HTML and Export HTML/CSV commands
20. New Analysis: Implemented "Wait for backfill" option. This slows down analysis sequence so AmiBroker waits for external RT data source to deliver backfill data
21. New Analysis: Custom backtester uses "last backtest settings" when calling GetStatus() instead of old AA settings
22. New Analysis: auto-repeat interval edit field did not allow to enter values if moved to main toolbar via customization. Fixed.
23. Formula Editor Analysis toolbar button now operates on New Analysis window
24. Default for timestamping of intraday compression changed to "Show START time of interval"
25. Charts: Tooltips automatically display also OHL prices (in addition to close) when Plot style is set to candlestick, bar or when PlotOHLC was used
26. Charts: AFL error message color is now definable in Tools->Preferences, "Color" tab

CHANGES FOR VERSION 5.48.0 (as compared to 5.47.0)

1. New Analysis: custom metrics columns were invisible in backtest/optimizations. Fixed. (#91031)
2. New Analysis: backtest did not display proper column names when Report mode was different than trade list. Fixed. Also added support for changing report mode via SetOption().
3. New Analysis: Auto-repeat Scan/Explore implemented (aka. "Run every" in old AA) (use drop down menu next to "Settings" button)
4. New Analysis: Showing arrows by double click implemented
5. New Analysis: Sync chart on select option implemented (use drop down menu next to "Settings" button)
6. Fixed window activation issue after RMB click in chart window when non-chart floating windows are active
7. New Analysis: Cancelling walk-forward did not restore date range and settings and didn't reset internal step counter. Fixed.
8. New Analysis: Formula path disappeared when window was made floating. Fixed.
9. New Analysis: in 5.47 non-exhaustive optimizers sometimes stopped after first step in walk-forward. Fixed.
10. Charting: scroll bar zoom function remains active even at extreme zoom in levels
11. New Analysis: Fixed problem with opt steps warning dialog appearing sometimes in the out-of-sample tests in walk forward sequence
12. New Analysis: Signal heaps are separated now, allowing to run concurrent backtest/optimizations in many analysis windows
13. New Analysis: removed unnecessary refreshes of symbol list during optimizations that caused slowdowns when user had large database
14. New Analysis: The size of control fields is properly adjusted with regards to DPI
15. New Analysis: Status("StockNum") was always zero in 5.47 and earlier. Now it is set properly.
16. Fixed Error 53 message that was giving an error when proper \" (quotation mark espace sequence) was used

CHANGES FOR VERSION 5.47.0 (as compared to 5.46.0)

1. New Analysis: implemented Walk-Forward testing (use drop arrow next to Optimization button)
2. New Analysis: last used ApplyTo/Range/From/to dates/filters and other settings are saved when Analysis window is closed
3. Fibonacci retracement- modifying Z-order affected only control trendline, not all lines as it should. Fixed.
4. Default title for new analysis window is "AnalysisX" (instead of "Unnamed") where X is consecutive number 1, 2..
5. attempt to use Say() on computer without sound card or without driver installed does not result in throwing exception/crash report, but it is rather silently ignored
6. AFL engine: new error 53: incorrect \ espace sequence. Error is issued when user forgets that single slash must be written as \\
7. Fixed "slow response" problems some users reported when switching symbols)

CHANGES FOR VERSION 5.46.0 (as compared to 5.45.0)

1. New Analysis: Exhaustive multi-threaded optimization implemented
2. New Analysis: Smart (non-exhaustive) multi-threaded optimization implemented in a way compatible with existing optimizer plugins
3. Slight modification to the way how compressed bar charts are drawn (so bars with H==L are better visible)

CHANGES FOR VERSION 5.45.0 (as compared to 5.44.1)

V3.0.1 CHANGES (as compared to version 3.0.0)

• Removed limit of backfill length (full intraday history provided by IQFeed can be downloaded)

V3.0.0 CHANGES (as compared to version 2.0.2)

• Implemented tracking of streaming symbols accross multiple clients via S,STATS
• Uses new method of staring up IQFeed (command line), asynchronous operation (no wait for plugin)
• Aux fields initialized properly to zero
• Native 64-bit version implemented

IMPORTANT: this plugin uses NEW IQFeed Client 4.8.1.7
ftp://www.dtniq.com/beta/iqfeed_client_4_8_1_7.exe or higher. Older Client API versions will not work.

The biggest improvement can be seen when using 1-, 5- and 15- second databases.Thanks to new IQFeed API the plugin does not need to download tick data anymore to construct second bars as second bars are now natively supported by IQFeed API. This dramatically decreases the amount of data that needs to be downloaded and increases the speed of backfill for N-second databases.

Also improved is backfill in other intervals.
