Increment take profit and Lot size

New comment
 

Hello I have written this piece of code into my EA but it's not working kindly help me correct the bug and make it function well: 

Below are the the conditions under which the function should follow: 

Every time a multiple of "n_op" successive loss-making operations is reached, the EA increases both the lot and the TP. If e.g. n_op=5 and we have just closed the fourth trade at a loss, the fifth trade will have tp and lot as follows set Y = (number of subsequent losing operations +1) / n_op. When Y is an integer we apply the lot and TP change to the trade we are opening, holding and using the Y value as follows lot: lot_start + lot_incr x Y tp: opening quota + take_profit x take_profit_multiplier x Y.

Belo is also my written code though not working. Help me solve this as per the conditions. Thank you.

void UpdateLotAndTP(int successiveLosses)
  {
     double y = (successiveLosses + 1) / n_op;
     
     if(y >= 1 && (int)y == y)
       {
          double newLot = lotto_inizio + lotto_incr * y;
          int newTP = (take_profit * Point) + (take_profit_multplier * take_profit) * y;
          
           lotto_inizio = newLot;
           take_profit = newTP;
       }
  }
//+------------------------------------------------------------------+
int  countSuccessiveLosses()
  {
      int consecutiveLosses = 0;
      int totalOrders = OrdersHistoryTotal();
      
      for(int i = totalOrders - 1; i >= 0; i--)
         {
             if(!OrderSelect(i,SELECT_BY_POS,MODE_TRADES))continue;
             if(OrderSymbol() != Symbol())continue;
             
             if(OrderProfit() < 0)
               {
                  consecutiveLosses++;
               }
             else
               {
                  break;
               }  
         }
      return consecutiveLosses;   
  }

I’m 85% sure the function for consecutive loses does not truly return the correct number of consecutive losses 
 

MODE_TRADES is used to search the open trades only, right?

from mt4 documentation...

OrderSelect

pool=MODE_TRADES

[in]  Optional order pool index. Used when the selected parameter is SELECT_BY_POS. It can be any of the following values:

MODE_TRADES (default)- order selected from trading pool(opened and pending orders),
MODE_HISTORY - order selected from history pool (closed and canceled order).

You mean I should use MODE_HISTORY instead

 
Your code will only report the total number of losses. if you want just the consecutive losses, then you will need to search for order by date first. And I suggest that you search codebase. There will be some scripts or codes in there that are already made to do what you want.

Open or pending.

Revo Trades #: MODE_HISTORY - order selected from history pool (closed and canceled order).

  3. Total Profit is OrderProfit() + OrderSwap() + OrderCommission(). Some brokers don't use the Commission/Swap fields. Instead, they add balance entries. (Maybe related to Government required accounting/tax laws.)
