order management problem

New comment
 

hi i created this simple concept of my expert so i can show you whats the problem

expert has to run in diffrent charts of the same currency pair so i have to apply magic number to each order and the basic concept of it is that i have to open the next order based on the results of the last one

for  example a sell if the previous orders hit stoploss a buy if it hits tp

the expert works fine until it goes up ...for example the first order  which is a buy hits tp and it has to open a sell well it opens a sell and it opens a buy which was the previous order at the same time

instead of one order it opens twp orders the order that it should open and again the previous one

from my tests the problem is magic number if i dont apply magic number the problem is solved but i have to apply it.. so im kinda stuck

here is my code

double pips;
extern int magic_n=88229;
extern int magic_n2=29522;

//+------------------------------------------------------------------+
//| Expert initialization function                                   |

double ticksize=MarketInfo(Symbol(),MODE_TICKSIZE);
   if(ticksize==0.00001||ticksize==0.001)
   pips=ticksize*10;
   else pips=ticksize;

//---
   return(INIT_SUCCEEDED);
  }
//+------------------------------------------------------------------+

THANK YOU IN ADVANCE

Looks like this check:

   //THE FIRST ORDER
   if(open_pairr(Symbol(),magic_n)<1)
   {
   entry(Symbol(),OP_SELL,0.01,0,5,35,35,NULL,magic_n);
   
   }

will be passed and entry() will execute every time (in fact, every tick) that there is no order with magic_n open. I assume this code is not in the other EA that you run in another chart?

Another problem is when you check OrdersHistoryTotal(), you should also check the orders' time, otherwise, as time goes by, you'll always get a history order that close by TP or SL, all the time. Not posing huge problem at the moment if you're only running two charts, and you're also checking your magic_n and magic_n2, but the logic is incomplete.

  
if(OrderClosePrice()==OrderStopLoss())
  1. SL becomes a market order when hit. Slippage could be multiple pips.

  2. Doubles are rarely equal. Understand the links in:
