Hi,
Ok let me try to explain again.
I have a file with
run = Optimize ("run", 1,1,1000,1);
SetOption("UseCustomBacktestProc", True );
SetCustomBacktestProc( "C:\\Program
Files\\Amibroker1\\Formulas\\Custom\\custom_backtest.afl" );
SetOption("MaxOpenPositions", 5 );
SetOption("InitialEquity", 100000 );
SetOption("AllowPositionShrinking", True );
SetOption ("AllowSameBarExit", False);
SetOption ("ActivateStopsImmediately", False);
SetOption ("MinShares", 100);
SetOption ("MinPosValue", 5000);
SetOption ("PriceBoundChecking", True);
SetOption ("CommissionMode", 2);
SetOption ("CommissionAmount", 25);
SetOption ("AccountMargin", 100);
SetOption ("ReverseSignalForcesExit", True);
SetOption ("UsePrevBarEquityForPosSizing", True);
SetOption ("PortfolioReportMode",0 );
ShortTrades = ParamToggle("Short Trades?","Oui|Non",1);
Longtrades = ParamToggle("Long Trades?","Oui|Non",1);
PositionScore = Random();
buy=....;
sell=.....;
short=.... etc.
Then, in c:\\Program
Files\\Amibroker1\\Formulas\\Custom\\custom_backtest.afl I have another file
with
SetOption("MaxOpenPositions", 5 );
SetOption("InitialEquity", 100000 );
SetOption("AllowPositionShrinking", True );
SetOption ("AllowSameBarExit", False);
SetOption ("ActivateStopsImmediately", False);
SetOption ("MinShares", 100);
SetOption ("MinPosValue", 5000);
SetOption ("PriceBoundChecking", True);
SetOption ("CommissionMode", 2);
SetOption ("CommissionAmount", 25);
SetOption ("AccountMargin", 100);
SetOption ("ReverseSignalForcesExit", True);
SetOption ("UsePrevBarEquityForPosSizing", True);
SetOption ("PortfolioReportMode",0 );
and when I click "backtest" nothing happens if
SetOption("UseCustomBacktestProc", True );
but it works well if
SetOption("UseCustomBacktestProc", False);
but of course I'd prefer to use the custom backtest.
Also, if I click the "use custom backtest" in the AB interface and choose
the first file or the second, still nothing happens if custombacktestproc is
true. It has to be false for results to show.
Can you help?
Thanks,
Louis
