[amibroker] Backtester does not use cumulative profits for position sizing

["cagigas00" <cagigas00@xxxxxxxx>]

Hello,

I am testing a fixed risk strategy (from Howard Bandy 1st book, figure 
22.20) but I can see that the number of shares is not calculated with 
the total equity (initial + cumulative profits), instead the backtester 
calculates the maximun number of shares for the initial capital and the 
specified risk .

Why this? Is there a problem with e=equity()? I am using amibroker 5.20 
in windows XP. Maybe there is an option somewhere or something that I 
am missing.

Thanks
Oscar

//TestingRiskPerTrade.afl
SetOption("InitialEquity",50000);
RiskPerTrade = 0.02;	//2%
RiskInPoints = 2.0 * ATR(20);
e = Equity();
Shares = RiskPerTrade * e / RiskInPoints;
SetPositionSize(shares,spsShares);
Buy = Cross(MA(C,8),MA(C,7));
Sell = Cross(MA(C,7),MA(C,8));
Plot(e,"eq",colorBlue,styleLine|styleOwnScale);
