Need help for martingal

[tabadany19]

Please help me for this EA

I want that the martingal willl be applied per pair

Eg: If the gbpusd was lost for the last trade, so the martingal will be applied on gbpusd only once gbpusd will appear

Thanks in advance sir

extern double Lot=0.01; 

extern bool Martingale=true; //martingale

extern double Multiplier=2; //multiplier

int MagicNumber=1234567890;

double last_profit,last_lot;
string last_tip,last_pair;



int start(){



double lot;

if( TotalOrdersCount()==0 ) {

//martingale

if(Martingale=true){

if(last_profit>=0){

lot=Lot;}

if(last_profit<0){

lot=Lot*Multiplier;}

}
else if(Martingale=false)
 {

   lot=Lot;

  }

}

}



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);

}

 

double last_history_profit()

   {

   double cpte_profit = 0; //int Magik_No = -1;

        if( OrderSelect(OrdersHistoryTotal()-1,SELECT_BY_POS,MODE_HISTORY) )    

          {

           if( OrderMagicNumber() == MagicNumber ) {

           last_profit  = OrderProfit();

           last_lot = OrderLots();

           last_tip = OrderType();
           
           last_pair= OrderSymbol();

          } 

       }

  return(1);

 }

Martingale, guaranteed to blow your account eventually. If it's not profitable without, it is definitely not profitable with.
