RiskPercentage & MaxSpread code help

 

Good afternoon,

I have a simple script that I developed:

Buy Close ( 1 ) > Close ( 2) / Sell Close ( 1 ) < Close (2)

that serves me well in the type of strategy and asset use .

However wanted to add two parameters :

RiskPercent - Percentage of capital allocated to each operation , the batch varies according to the accumulated assets .

MaxSpread - maximum Spreed accepted to enter into a transaction.

Anyone can help me?

See the code below:

extern int MagicNumber=10001;

extern double Lots =0.01;

extern double StopLoss=0;

extern double TakeProfit=0;

extern int TrailingStop=0;

extern int Slippage=3;

//+------------------------------------------------------------------+

// expert start function

//+------------------------------------------------------------------+

int start()

{

double MyPoint=Point;

if(Digits==3 || Digits==5) MyPoint=Point*10;

double TheStopLoss=0;

double TheTakeProfit=0;

if( TotalOrdersCount()==0 )

{

int result=0;

if((Close[1]>Close[2])) // Here is your open buy rule

{

result=OrderSend(Symbol(),OP_BUY,Lots,Ask,Slippage,0,0,"EA Generator www.ForexEAdvisor.com",MagicNumber,0,Blue);

if(result>0)

{

TheStopLoss=0;

TheTakeProfit=0;

if(TakeProfit>0) TheTakeProfit=Ask+TakeProfit*MyPoint;

if(StopLoss>0) TheStopLoss=Ask-StopLoss*MyPoint;

OrderSelect(result,SELECT_BY_TICKET);

OrderModify(OrderTicket(),OrderOpenPrice(),NormalizeDouble(TheStopLoss,Digits),NormalizeDouble(TheTakeProfit,Digits),0,Green);

}

return(0);

}

if((Close[1]<Close[2])) // Here is your open Sell rule

{

result=OrderSend(Symbol(),OP_SELL,Lots,Bid,Slippage,0,0,"EA Generator www.ForexEAdvisor.com",MagicNumber,0,Red);

if(result>0)

{

TheStopLoss=0;

TheTakeProfit=0;

if(TakeProfit>0) TheTakeProfit=Bid-TakeProfit*MyPoint;

if(StopLoss>0) TheStopLoss=Bid+StopLoss*MyPoint;

OrderSelect(result,SELECT_BY_TICKET);

OrderModify(OrderTicket(),OrderOpenPrice(),NormalizeDouble(TheStopLoss,Digits),NormalizeDouble(TheTakeProfit,Digits),0,Green);

}

return(0);

}

}

for(int cnt=0;cnt<OrdersTotal();cnt++)

{

OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES);

if(OrderType()<=OP_SELL &&

OrderSymbol()==Symbol() &&

OrderMagicNumber()==MagicNumber

)

{

if(OrderType()==OP_BUY)

{

if((Close[1]<Close[2])) //here is your close buy rule

{

OrderClose(OrderTicket(),OrderLots(),OrderClosePrice(),Slippage,Red);

}

if(TrailingStop>0)

{

if(Bid-OrderOpenPrice()>MyPoint*TrailingStop)

{

if(OrderStopLoss()<Bid-MyPoint*TrailingStop)

{

OrderModify(OrderTicket(),OrderOpenPrice(),Bid-TrailingStop*MyPoint,OrderTakeProfit(),0,Green);

return(0);

}

}

}

}

else

{

if((Close[1]>Close[2])) // here is your close sell rule

{

OrderClose(OrderTicket(),OrderLots(),OrderClosePrice(),Slippage,Red);

}

if(TrailingStop>0)

{

if((OrderOpenPrice()-Ask)>(MyPoint*TrailingStop))

{

if((OrderStopLoss()>(Ask+MyPoint*TrailingStop)) || (OrderStopLoss()==0))

{

OrderModify(OrderTicket(),OrderOpenPrice(),Ask+MyPoint*TrailingStop,OrderTakeProfit(),0,Red);

return(0);

}

}

}

}

}

}

return(0);

}

int TotalOrdersCount()

{

int result=0;

for(int i=0;i<OrdersTotal();i++)

{

OrderSelect(i,SELECT_BY_POS ,MODE_TRADES);

if (OrderMagicNumber()==MagicNumber) result++;

}

return (result);

}
