Good afternoon, continuing to get to grips with coding, took the example EA from the tutorial section article, replaced the code from the example:

To an arbitrary one for training purposes:

The trades don't show up, could you please tell me what's the reason, how to fix the code.

double MA_1[]; // нет обьявления размера, не видно как (локально или глобально) обьявлен, 
// не видно оператора двигающего индекс массива.
// лучше пока не освоили работу с массивами обьявите переменные и не парьтесь

  double MA_0=iMA(NULL,0,Period_MA,0,MODE_EMA,PRICE_CLOSE,0);
  double MA_1=iMA(NULL,0,Period_MA,0,MODE_EMA,PRICE_CLOSE,1);
  
  if (MA_1 < MA_0)
     {                                          // ..МА последнего бара выше предыдущего
      Opn_B=true;                               // Критерий откр. Buy
      Cls_S=true;                               // Критерий закр. Sell
     }
   if (MA_1 > MA_0)
     {                                          // ..МА последнего бара ниже предыдущего
      Opn_S=true;                               // Критерий откр. Sell
      Cls_B=true;                               // Критерий закр. Buy
     }

Urain, thank you, I never cease to be amazed at the logic of mql, and if you try to use for(int i=1; to try, the script will not simplify - could you tell me how to format it, I cannot yet feel the logic of the language, how to define the operator that moves the array?

P. S. I declared the array, by mistake in the example script has removed:

   double MA_1[];
   ArrayResize(MA_1,Period_MA);

   MA_1[0]=iMA(NULL,0,Period_MA,0,MODE_EMA,PRICE_CLOSE,0);

   if (MA_1[1] < MA_1[0])
     {                                          // 
      Opn_B=true;                               // Критерий откр. Buy
      Cls_S=true;                               // Критерий закр. Sell
     }
   if (MA_1[1] > MA_1[0])
     {                                          // 
      Opn_S=true;                               // Критерий откр. Sell
      Cls_B=true;                               // Критерий закр. Buy
     }

Abzasc:
Differences in prices. As a consequence, different, to the contrary, indicator results...

I don't see anything different there. Forget the indicators, once again, the right one for you is the one you're trading on. You're not concentrating on the right one at all.

Good afternoon. An array has been declared, the operator that moves the array index has been set, but the orders are not being placed. Please tell me what is wrong.

   double MA_1[];
   ArrayResize(MA_1,Period_MA);

   for(int j=0;j<=Period_MA-1;j++)
   MA_1[j]=iMA(NULL,0,Period_MA,0,MODE_EMA,PRICE_CLOSE,j);

   
   if (MA_1[j+1] < MA_1[j])
     {                                          // 
      Opn_B=true;                               // Критерий откр. Buy
      Cls_S=true;                               // Критерий закр. Sell
     }
   if (MA_1[j+1] > MA_1[j])
     {                                          // 
      Opn_S=true;                               // Критерий откр. Sell
      Cls_B=true;                               // Критерий закр. Buy

TryOrderSend, then it works...

Have you read the standard MetaEditore helper? If not, read the whole...

Can you guys tell me if it's possible to rewrite Igor Kim's function, which closes all losing orders, whose loss exceeds a certain value:

//+----------------------------------------------------------------------------+

//|  Версия   : 25.04.2008                                                     |
//|  Описание : Закрытие тех позиций, у которых убыток в валюте депозита       |

//+----------------------------------------------------------------------------+
//|  Параметры:                                                                |

//|    op - операция                   (-1   - любая позиция)                  |
//|    mn - MagicNumber                (-1   - любой магик)                    |
//|    pr - профит/убыток                                                      |
//+----------------------------------------------------------------------------+
void ClosePosBySizeLossInCurrency(string sy="", int op=-1, int mn=-1, double pr=0) {
  int i, k=OrdersTotal();

  if (sy=="0") sy=Symbol();
  for (i=k-1; i>=0; i--) {
    if (OrderSelect(i, SELECT_BY_POS, MODE_TRADES)) {
      if ((OrderSymbol()==sy || sy=="") && (op<0 || OrderType()==op)) {
        if (OrderType()==OP_BUY || OrderType()==OP_SELL) {
          if (mn<0 || OrderMagicNumber()==mn) {
            if (OrderProfit()+OrderSwap()<-MathAbs(pr)) ClosePosBySelect();
          }
        }
      }
    }
  }
}

I need to find one open position that has the largest loss.
The point is that I need to find the position with more profit than the losing one and close them in counter-close.
Maybe someone has some experience with this, or has faced such a problem?

Why can't three indicators based on different principles show almost the same picture (spearman, stochastic, and mcdrsy) - but can't show the right movement and entry with a probability above 60%?

Mikhail Toptunov 2010.06.05 15:45 #5969

Hi there, I am wondering what code is needed to close an order after it has passed point X in profit and has started to go down to point Y>OrderOpenPrice and then needs to close it.
