how is it best to breakeven

Okay, i'am just using profit amounts to place a stop if order profit is greater than or equal to half of  the expected profit

in tester the resulting journal entry says OrderModify error 1.  what is wrong just using orderopenprice for stoploss?

int OnInit()
 {
 sSymbol=Symbol(); 
 iType=-1;
 iDigits=Digits;
 if(iDigits==3){iMultiplier=100;} 
 if(iDigits==5){iMultiplier=10000;}
 return(INIT_SUCCEEDED);
 }

void OnBreakEven()
 {
 for(int iTickets=OrdersTotal()-1; iTickets>=0; iTickets--)
  {
  if(!OrderSelect(iTickets,SELECT_BY_POS,MODE_TRADES)){continue;}
   {
   if(OrderType()<=OP_SELL && OrderSymbol()==sSymbol && OrderMagicNumber()==iMagic())
    {
    if(OrderType()==OP_BUY && 
    OrderProfit()>=NormalizeDouble((OrderTakeProfit()-OrderOpenPrice())*iMultiplier*OrderLots()*10/2,2))
     {
     if(OrderModify(OrderTicket(),OrderOpenPrice(),OrderOpenPrice(),OrderTakeProfit(),0,CLR_NONE))
      {/*Print("***BREAKEVEN HAS BEEN MET***");*/return;}
     else
      {
      Print("CANNOT BREAKEVEN -- PROFIT("+OrderProfit()+") NOT >= ("+
      NormalizeDouble((OrderTakeProfit()-OrderOpenPrice())*iMultiplier*OrderLots()*10/2,2)+
      ")...( TP("+OrderTakeProfit()+")-OPEN("+OrderOpenPrice()+")="+
      ((OrderTakeProfit()-OrderOpenPrice())*iMultiplier)+" ) *ORDERLOTS("+OrderLots()+") / 2");
      return;
      }
     }
    if(OrderType()==OP_SELL && 
     OrderProfit()>=NormalizeDouble((OrderOpenPrice()-OrderTakeProfit())*iMultiplier*OrderLots()*10/2,2))
     {
     if(OrderModify(OrderTicket(),OrderOpenPrice(),OrderOpenPrice(),OrderTakeProfit(),0,CLR_NONE))
      {/*Print("***BREAKEVEN HAS BEEN MET***");*/return;}
     else
      {
      Print("CANNOT BREAKEVEN -- PROFIT("+OrderProfit()+") NOT >= ("+
      NormalizeDouble((OrderOpenPrice()-OrderTakeProfit())*iMultiplier*OrderLots()*10/2,2)+
      ")...( OPEN("+OrderOpenPrice()+")-TP("+OrderTakeProfit()+")="+
      ((OrderOpenPrice()-OrderTakeProfit())*iMultiplier)+" ) *ORDERLOTS("+OrderLots()+") / 2");
      }
     }
    }
   }
  }
 }

though it seems to be working it does get errors (picture updated)


 

You seem to be assuming that 1 pip is worth 10 $, not sure because I can't work out what you are trying to do.

  if(OrderClosePrice()-OrderOpenPrice()>=(OrderTakeProfit()-OrderOpenPrice())/2)

 is much simpler. Above is for a Buy order obviously

You should also check if the SL has already been modified

ok ive modified my original code

//+-------------------------------------------------------------------+
void OnBreakEven()
 {
 for(int iTickets=OrdersTotal()-1; iTickets>=0; iTickets--)
  {
  if(!OrderSelect(iTickets,SELECT_BY_POS,MODE_TRADES)){continue;}
  if(OrderType()>OP_SELL||OrderSymbol()!=sSymbol||OrderMagicNumber()!=iMagic()){continue;}
  // sells
  if(OrderType()==OP_SELL && OrderOpenPrice()-OrderClosePrice() >=
    (OrderOpenPrice()-OrderTakeProfit())*dBreakEvenPercent && 
     OrderStopLoss()!=OrderOpenPrice())
    {
    if(OrderModify(OrderTicket(),OrderOpenPrice(),OrderOpenPrice(),OrderTakeProfit(),0,CLR_NONE))
    {return;}
    }
  //buys
  if(OrderType()==OP_BUY && OrderClosePrice()-OrderOpenPrice() >=
    (OrderTakeProfit()-OrderOpenPrice())*dBreakEvenPercent && 
     OrderStopLoss()!=OrderOpenPrice())
    {
    if(OrderModify(OrderTicket(),OrderOpenPrice(),OrderOpenPrice(),OrderTakeProfit(),0,CLR_NONE))
    {return;}
    }
  } 
 }

seems im still getting the OrderModify Error 1 and it seems to begin even before any orders are present

again it does work.. it seems like it does it and other times not
