[amibroker] code for a half-on-loss strategy (chande)

["cagigas00" <cagigas00@xxxxxxxx>]

The following code implements a half-on-loss strategy (chande, "beyond 
technical analysis) with stocks. The risk depends on the outcome of 
the previous trade (regardless long or short). If previous trade was a 
winner then risk=6% of total equity. If previous trade was a loser 
then risk=3% of total equity.


//-----------------------------------------------------//
e=Equity(1);
profit_l=ValueWhen(Sell,e)-ValueWhen(Ref(Buy,-1),e);
profit_s=ValueWhen(Cover,e)-ValueWhen(Ref(Short,-1),e);
longt= profit_l != Ref(profit_l,-1);
Shortt=profit_s != Ref(profit_s,-1);
profit=Flip(Longt,Shortt)*profit_l+Flip(Shortt,Longt)*profit_s;
Plot(profit_l,"ProfitL",colorBlue,styleLine);
Plot(profit_s,"ProfitS",colorGreen,styleLine);
Plot(profit,"Profit",colorBrown,styleLine);
rsk=IIf(profit>0,6,3);
Plot(rsk,"risk",colorRed,styleLine);
Risk = rsk*0.01* Equity(1);
Shares = risk/ATR(10);
PositionSize = shares * BuyPrice;
