Martingale

[tabadany19]

anyone can help me?

I want to code an EA with martingal,and I want that the martingal will be applied for the lost pair only not for all pairs.

Eg: 

The ea place an order buy at GBPUSD and sell at EURUSD

The GBPUSD was closed at a profit first but the EURUSD was closed at a loss secondly.

For the next trade,the martingal will be applied if the next order is EURUSD,if not(EURJPY for instance) the martingal will not be applied(initial lot size)

And this is my other suggestion (which came from tsd 2010 and from tsd 2008):

----------------

Just to remind:

Coders (any coder) are coding for free:

• if it is interesting for them personally, or
• if it is interesting for many members of this forum.

----------------

and Freelance section of the forum should be used in most of the cases.

ok sir; This is the code for martingal; it should be like this: for eg: when the last profit of gbpusd was lost; the martingal should be applied for gbpusd only

Another eg: Those are the history of the account(intial lot 0.01, and multiplier x2)

GBPUSD -5

So if the next pair is not GBPUSD, there is no martingal applied; but if the next signal is GBPUSD the martingal is applied

Like this: 

1st GBPUSD -5  lot 0.01

2nd GBPUSD 11 lot 0.02

OR

1st GBPUSD -5 lot 0.01

2nd EURUSD 7 lot 0.01 //no martingal here because it is not a gbpusd

3rd GBPUSD 13 lot 0.02 //the martingal is applied because there is a GBPUSD

So help me please because my code do not work like this condition

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);
