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,

Subject: [amibroker] Can someone fix this
OLE code?
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!!!!
herman
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( "" );
}
