AmiQuote -

Downloading quotes

Download from Quote.com fails
with 'the connection with the server is reset'

 Livecharts password incorrect or not entered properly as described here

Please go to the AmiQuote SETTINGS page, UNMARK "Use livecharts account" and select "SERVER #1" or follow exactly the instructions here

Download from Yahoo starts fine but then stops

(especially on DSL, ADSL, cable modem connections)

 Yahoo is blocking you. After infamous Internet worm attack, Yahoo considers quick, repeating multiple downloads as a "denial of service" attack.

If possible reconnect with diffferent IP (otherwise you would need to wait half an hour or more until Yahoo unblocks you)

go to the AmiQuote "Settings" and set "Initial delay between requests" to 1000 and "max number of simultaneous downloads" to 1.

Download from Yahoo fails

It may be too soon to get historical data from Yahoo or

Yahoo temporary problem

First check Yahoo historical page:

http://table.finance.yahoo.com/k?s=utx&g=d

replace utx by the symbol in question.
===========================

If the page shows old quotes - it is the problem with Yahoo not with AmiQuote.

In fact AmiQuote uses
" Download spreadsheet format" link on previously mentioned page:
http://table.finance.yahoo.com/k?s=utx&g=d

If historical data are not available you can always use "Current" mode of AMiQuote to get the data of today (even during trading hours)

If you do not know the ticker symbol for index or stock or mutual fund please
use symbol lookup feature:
a) at Yahoo (for historical and current modes):
http://finance.yahoo.com/l

b) at Lycos (for Intraday mode):
http://finance.lycos.com/home/misc/symbol_search.asp
Download works but there are no quotes added Local configuration problem

Follow these steps to troubleshoot the problem

  • Go to C:\Program Files\AmiBroker\AmiQuote\Download and check if .AQH files are there.
  • Open them with Notepad and see if data are there
  • Check if you have aqh.format file in the Formats subdirectory of AMiBroker
  • Check its contents and eventually send me for checking
  • Try to import manually as per instructions given in the user's guide
  • If you ever restored data directory from CD ROM check the "read-only" flag of data files in AmiBroker database. They must not be read-only. If they are you have to mark all files in the data directory and all subfolders and UNMARK read only flag.
Download from any source fails Connection problem Please check your internet connection. If you are using firewall make sure to allow AmiQuote (QUOTE.EXE) to access the internet on ports 80 and 443.

Miscellaneous questions

Question

 Answer
Must I use Internet Explorer? Can I use Netscape Navigator, Opera, (other browser) instead?
You can use any browser. In certain server versions of Windows it must be selected to be installed. Internet Explorer is now just a part of operating system and AmiBroker uses extensively those parts. But you don't need to use Internet Explorer.
Where is the help file (manual)?

User's guide is available from Help->Help topics menu in AmiBroker (accessible also by F1 key)
