Hello,
 
Windows OLE provides automatic coercing of types, so you can use for example strings in ISO format (YYYY-MM-DD)
 
AA.RangeFromDate = "2003-04-12";
AA.RangeToDate = "2003-11-03";

Thanks Thomasz, I'll give it a shut. Can you please help on how to define RangeFromDate and RangeToDate? I appreciate your assistance.

Hello,
 
Backtest(2) is OLD backtester. Do not use it until you have some 'legacy' code (from version 4.40 or earlier).
 
Use Backtest(0) for portfolio backtest.
 
AA.Report works but you have to provide correct file name (note that backslash in the path should be written as \\ ) or empty string to display.
For debugging purposes I suggest you to run exactly the code sample provided in the help:
 
 
/* run backtest and display report */
AA.Backtest();
AA.Report(""); // empty file name means display report

Thomasz, you're incredible - GREAT FEATURE OF AB!!!
 
However, I can't seem to export the backtest result to a HTML file, when running Backtest(0) and then AA.Report. No HTML file is being generated. Interesting to note, though:
1) When running Backtest(2) it DOES export the backtest result list - a long HTML file, containing PER SYMBOL data. I'm interested though in the portfolio behaviour, and less in per symbol info.
2) When running BackTest(2), Export (AA.Export) DOES WORK, and exports trades etc to a CSV file. Unfortunately, as stated, AA.Report doesn't seem to work. Can you, or anyone else, please help?
 
Another issue, if you won't mind: say I'm interested the test period to be 12/4/2003 to 3/11/2003. I'm defining the following:
AA.RangeMode=3;
Now, I'm not sure how to handle a DATE variable. Can you please help defining RangeFromDate and RangeToDate? Thanks.

Of course there is a way, just look into help file:

Hi Folks,
 
I have a system that I'd like to test on different time periods. I have some 150 different intervals that I'd like to check - the system is obviously constant, the only thing that changes from test to test is the STARTING PERIOD and ENDING PERIOD.
Is there a way one can automate AB's backtester, and thus "save" the frustrating manual changing of the "START" and "END" dates?
 
Thanks,
Short,
