[amibroker] sigscalein positionsize problem

["nightscalper" <nightscalper@xxxxxxxx>]

Hi to all,

may I ask for your help with the following code.

The positionsize does not behave as it should.
I am trying to buy "100" at first occurence of buy 
signal and when scalein condition appears (drawdown), 
I want to buy "100000", but backtester does set 
positionsize sometimes right and sometimes not, 
e.g. it buys "100000", even if it´s the first occurence 
of buy signal, or buys "100", even if it´s a scalein 
signal. But sometime backtester does it correct. I 
just don´t get it. Initial equity in backtestersettings
is 1,000,000, so this should be no problem. 

Thanks for any help finding what is wrong with the code.

Regards
robert

Sell = C<0;

ApplyStop(stopTypeProfit,stopModePoint,0.0030,1,False,1);

e = Equity(1);  

PyramidThreshold = 0.1; 
PcntProfit = 100*(e-ValueWhen(Buy,e))/ValueWhen(Buy,e); 
InTrade = Flip(Buy,Sell); 
DoScaleIn = ExRem(InTrade AND PcntProfit<-PyramidThreshold,Sell);
Buy = Buy + sigScaleIn * DoScaleIn;

PositionSize = IIf(DoScaleIn,100000,100);
