Hi,

I'm trying to write a function in MQL4 which will calculate my total profit (could be negative, which would mean loss) at a given price.

In other words, if I have an open Buy order at price P1 then:

my profit at P2 would be ((P2-P1) * volume) - but that's in most simplistic terms, now I need to do that for all open orders, and account for Buys and Sells and also Account for Spread and the fact that Buys open with Ask and close with Bid and vice versa, Sells open with Bid and close with Asks.

 

I know this might be an easy exercise for a good programmer, but I'm just being lost in all these details and can't seem to get it right. Can someone help me out here? In other words, I need something similar to a sum of all OrderProfit() for my open orders but calculated at a given price instead of current.

 

Thanks!

Would something like this help??

RodionPronin: my profit at P2 would be ((P2-P1) * volume) - but that's in most simplistic terms, now I need to do that for all open orders, and account for Buys and Sells and also Account for Spread and the fact that Buys open with Ask and close with Bid and vice versa, Sells open with Bid and close with Asks.

  1. Just sum individual orders: (P2 - OrderOpenPrice) *Direction(OrderType) * OrderLots * DeltaPerlot
    double   Direction(int op_xxx){ return( 1. - 2. * (op_xxx%2) );               }
    
  2. Spread and Bid/Ask are irrelevant. If you close at P2 the spread is included.
