Hi,
Is changed the code for my own two systems.
System1: Long, Sell, Profit, Stoploss.
System2: Long, Short, Sell, Cover, Profit, Stoploss.
But somehow the profit and lossstops do not function properly for
system1. Somewhere in the code must be a small misstake, which I
could not find. Anybody an idea?
BuySystem1 = Condition1 AND insession;
SellSystem1 = TimeNum() >= BTEndTime ;
LongStop = ValueWhen(Buysystem1,Low)-pds1;
TakeProfitAmount = pds2*(BuyPrice-LongStop);
LongStopAmount = BuyPrice - LongStop;
StopSystem1 = ApplyStop(stopTypeLoss,stopModePoint,LongStopAmount,
ExitAtStop = 1, volatile = False, ReEntryDelay = 0 );
ProfitSystem1 =ApplyStop
(stopTypeProfit,stopModePoint,TakeProfitAmount, ExitAtStop = 1,
volatile = False, ReEntryDelay = 0 );
BuySystem2 = Sum(buysig,2) > Sum(Sellsig,2) AND insession AND NOT
GapUp() OR GapDown() AND NOT Holiday;
ShortSystem2 = Sum(buysig,2) < Sum(Sellsig,2) AND insession AND NOT
GapDown() OR GapUp() AND NOT Holiday;
SellSystem2 = PDI(23) < pds14 AND Sum(buysig,2) > Sum(Sellsig,2) OR
MDI(23) > 35 AND Sum(buysig,2) > Sum(Sellsig,2) OR TimeNum() >=
BTEndTime;
CoverSystem2 = MDI(23) < pds15 AND Sum(buysig,2) < Sum(Sellsig,2) OR
PDI(23) > 35 AND Sum(buysig,2) < Sum(Sellsig,2) OR TimeNum() >=
BTEndTime;
System1IsLong = Flip(BuySystem1,SellSystem1);
System1IsFlat = Flip(SellSystem1,BuySystem1);
Buy = BuySystem1 OR (System1IsFlat AND BuySystem2) ;
Sell = SellSystem1 OR (System1IsFlat AND SellSystem2) ;
Short = System1IsFlat AND ShortSystem2 ;
Cover = System1IsFlat AND CoverSystem2 ;
StopSystem2 = ApplyStop(stopTypeLoss,stopModePoint,Optimize("max.
loss stop level",3.0,3.0,3.0,1.0),True,True,1 );
ProfitSystem2 = ApplyStop(stopTypeProfit,stopModePoint,Optimize("max.
profit stop level",55,55,55,5),True,True,1 );
SetTradeDelays(1,1,1,1);
Profit = System1IsLong AND Profitsystem1 OR (System1IsFlat AND
ProfitSystem2) ;
Loss = StopSystem2 OR (System1IsFlat AND StopSystem2) ;
PositionSize = 100 * 1;
