CHANGES FOR VERSION 5.57.1 (as compared to 5.57.0)

  1. When real-time quotes were streaming interval combo refreshed too often making it hard to enter new interval. Fixed.
  2. Entering custom interval in the combo did not always work correctly for floating windows in 5.57.0. Fixed.

CHANGES FOR VERSION 5.57.0 (as compared to 5.56.0)

  1. Charts/UI: now there is a new chart interval combo box that allows to either select predefined interval OR simply type ANY interval you want without the need to define it in the preferences

    Supported interval codes are:
    Y - yearly, Q - quarterly, M - monthly, W - weekly, D - daily, N - day/night,
    h - hourly, m -minute (note lowercase m), s - second, T - tick, R - range, V - volume.
    D, h, m, s, T, R, V intervals can be preceded by a number. So if you type 15m it means 15 minute chart, if you type 13T it means 13 tick chart, if you type 200R it means 200R (range) chart. If you type just a number (x) without the following letter it will treat it as x-minute chart.

  2. Tools->Auto update quotes is now native command (not a 'custom tool' as it was)
  3. Default "X grid spacing" changed to 50 (from original 60) pixels
  4. 12 hour X grid spacing replaced by 6 hour

CHANGES FOR VERSION 5.56.0 (as compared to 5.55.1)

  1. New Analysis: A new walk-forward summary report that covers all out-of-sample steps
  2. New Analysis: walk forward procedure now produces detailed reports for every out-of-sample step
  3. Enhanced backtest report: color-coding 'good' and 'bad' values in backtest report
  4. Report: a note added to tooltips for Sharpe ratio and UPI metrics telling where user can change risk-free rates for those metrics
  5. Report Explorer 1.0.2 - added alternate row background color
  6. Removed "00:00:00" time in the "date from" in the backtest report / settings page
  7. Param window: clicking on category that had exactly same name as parameter resulted in changing parameter value. Fixed.
  8. Analysis: all custom metrics were treated as numbers (for example got formatted with thousand separator). Now AmiBroker custom metrics of string type are treated as strings and do not get any extra formatting for the display.
  9. Added recommendation to activate multithreading to the performance warning tooltip when multithreading is currently turned OFF.

CHANGES FOR VERSION 5.55.1 (as compared to 5.54.0)

  1. Random characters could appear in list view clipboard copy in 5.55.0. Fixed in 5.55.1.
  2. _SECTION_BEGIN/_SECTION_END/_PARAM_VALUES appeared twice in auto-complete listbox. Fixed.
  3. SetOption("PortfolioReportMode", x ) changed exploration columns too. Fixed. (bmg#92)
  4. AFL: new function GetAsyncKeyState( vkey )
  5. AFL: Status() function supports new fields "lastbarend", "lastbartimeleft", "timeshift"
  6. List view clipboard copy now uses regional settings decimal separator.
  7. Charting: added left- and right extend option to the rectagle drawing tool
  8. List view date column sort was incorrect when regional settings time format was set to: H:mm:ss. Fixed.
  9. When multithreading in charts was turned OFF, drawing tools did not work properly in 5.53-5.54. Fixed.
  10. XYChartAddPoint does not generate error anymore when Null values are passed as X, Y co-ords. Instead it silently ignores such points (they are not plotted) and XYChartAddPoint returns FALSE (0)
  11. AFL: new function StaticVarInfo( "varname", "field" )

CHANGES FOR VERSION 5.54.0 (as compared to 5.53.1)

  1. New Analysis: "Sync chart on select" did not respect linked charts and symbol lock. Fixed.
  2. AFL: new function XYChartSetAxis( "chartname", "x-axis name", "y-axis name" )
  3. AFL: new function XYChartAddPoint( "chartname", "text", x, y, color )
  4. New Analysis: Implemented XY (scatter) charts in Explorations (see Read Me for the details)
  5. {{INTERVAL}} gave incorrect (unstable) results in custom n-tick/n-range/n-volume charts when used with multithreading. Fixed.
  6. Interval(2) returned incorrect (unstable) results in custom n-tick/n-range/n-volume charts when used with multithreading. Fixed.
  7. Preferences: Currency page was not working properly. Fixed.
  8. Status bar look matches now appearance settings (esp. visible in VS2012 style)
  9. Parameter window now allows to select combined styles (like styleHidden) as well as their components styleNoRescale+styleNoDraw independently
  10. User setting for minimum pixel spacing in X grid (Tools->Preferences, "Axes / Grids") - it is recommended to keep it at default value (60 pixels), for denser grid use less spacing (minimum 30 pixels), for wider grid use more x spacing (maximum 120 pixels)
  11. Sometimes panes did not refresh to final size when chart sheets are switched (for example - one tab has only one pane second tab has two panes). Fixed.

CHANGES FOR VERSION 5.53.1 (as compared to 5.53.0)

  1. Trend lines and other drawing tools sometimes were blinking or disappeared in 5.53.0. Fixed
  2. Plots with styleDashed mixed with plots using other styles could cause continuous growth of rendering time in 5.52/5.53. Fixed.

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
