Your code seems to work for me here.
Here it is again, just slightly tweaked:
//SETTINGS--->
PosQty=Param("Posiciones",10,1,20,1);
SetOption("InitialEquity", 1000000 );
SetOption("AllowPositionShrinking", True );
SetOption("MaxOpenPositions", PosQty );
SetOption ("accountmargin",100);
PositionSize = -100/(posqty);
Buy = Sell = Short = Cover = 0 ;
//-----------
ExitPct = Param( "ExitPct", 1, .1, 10, .1 ) ;
SetTradeDelays(1,1,1,1);//buy after signal
ApplyStop(stopTypeProfit, stopModePercent, ExitPct, 1); //exit intraday on same
bar at 2%
ApplyStop(stopTypeLoss, stopModePercent, ExitPct, 1); //exit intraday
on same bar at 2%
//CONDITIONS---------------------------------------
Cond1=Cross(MACD(12,26),0);
//long entry-----------------------------
PositionScore= 100-StochK(15,3);
Buy= Cond1;
// BuyPrice=Open*1.001; //in open next bar!
BuyPrice=Open ; //in open next bar!
Sell=Cross(Signal(12,26,9),MACD(12,26));//sell in open next bar
// SellPrice=Open*0.999;
SellPrice=Open ;
Buy=ExRem(Buy,Sell); Sell=ExRem(Sell,Buy);
//------------END OF CODE------------------
Notes:
1. My AB 5.3 install requires Buy, Sell, Stop, and Cover to all be defined.
2. I use the Open for BuyPrice and SellPrice. If you multiply the Open you
could wind up with a price that does not exist during that bar.
3. I parameterized the ExitPct, and added the stopTypeLoss.
4. When I run a backtest, results look good, with rows and rows of profit and
loss exits at the ExitPct, differing only in the 2nd decimal place.
So, I don't know why it isn't working for you ...
