Re: [amibroker] Can someone fix this OLE code?

[Tomasz Janeczko]

Hello,

First of all, AA can only be controlled from OUTSIDE of AmiBroker.
-----------------------------------------------------------------------------------------

Such code should never be run from the AA because it will create endlessly 
nested loop
(AA triggering AA triggering AA triggering AA ad infinituum)
It should also not be called from indicator because it will create endless loop 
too
(indicator->Backtest->triggers refresh->indicator->refresh.

As to errors you are getting:
1. AFL does not allow *setting* COM properties with parameters (it can only 
read them).
2. should be AA.RangeN (not AA.Analysis.RangeN).

Best regards,
Tomasz Janeczko

  Can someone help me fix the code below so that when triggered in an 
Indicator, it: 



  1) Backtest all tickers in watchlist WLN?

  2) Use range of BRS bars

  3) Output ONLY the one line BT Report?




  Many thanks!!!!

  if ( ParamTrigger( "Run Com BT", "BT" ) )

  {

      WLN = 0; // the watchlist to backtest

      BRS = 100; // Number bars to test

      AB = CreateObject( "Broker.Application" );

      AA = AB.Analysis;

      AA.LoadFormula( "C:\\Program 
Files\\AmiBroker\\Formulas\\Systems\\Example.afl" );

      AA.ClearFilters();

      AA.Filter( 0, "watchlist" ) = WLN;         // This gives syntax error...

      AA.ApplyTo = 1;

      AA.RangeMode = 1;

      AA.Analysis.RangeN = BRS;                 // This gives syntax error...

      AA.Backtest();

      AA.Report( "" );

  }
