Good afternoon,

Could you please tell me how to put a marker on the chart? For example, the order did not open, but at least to see on the chart, at which point it should have opened.

I would like to place a marker on a chart.

Like this

#include <stderror.mqh>

//+------------------------------------------------------------------+
//| expert start function                                            |
//+------------------------------------------------------------------+
int start()
  {
  int Err;
//----
       if(...........) //покупаем
          { 
          Err=OrderSend(..................);
             if(Err<0)
                SetArrow(159, Blue,"ошибка открытия № "+GetLastError(),Time[0],Open[0],2);
          }
       if(...........) //продаем
          { 
          Err=OrderSend(..................);
             if(Err<0)
                SetArrow(159, Red,"ошибка открытия № "+GetLastError(),Time[0],Open[0],2);
          }
//----
   return(0);
  }

Yeah sorry got confused, first time writing on the forum. Copypasted first, then decided to handwrite and got confused... But the example above is correct...

MA1>MA2 and MA1<MA3 and MA3<MA4


Read the following thread

There's something strange here.

MA1>MA2 and MA2>MA3 and then MA1<MA3

All the more so because it is sufficient to

Yes, indeed, there is a contradiction between the two. I just didn't look into everything! The author still has a long way to go to make "hard mistakes"!
 

The question is this. This is not the first time I've encountered this situation:

If the traal or breakeven function is called on every tick, for example, an error 1 will pop up. Which means, according to the documentation:

ERR_NO_RESULT   1       Нет ошибки, но результат неизвестен

If not called openly in start function, i.e. not just entered function with parameters directly in start, but call it on every bar, i.e. not by tick, then error - no...

I mean like this:

int start()
{
   MovingStopLossToBU();
// Что-то дальше делаем..

Why like this?

And in general, how is it more intelligently implemented? Will it be resource intensive on every tick?

 

Всем добрый день.

I need your help. I don't understand what's going on.

if (OrderStopLoss() != NormalizeDouble(t6,5))

{

a=10;

}

TheOrderStopLoss()=1.3017 andNormalizeDouble(t6,5)=1.3017 condition still holds, i.e. a=10. But it should not be satisfied.

What may be the reason for this?

I would advise you not to go by bars, by so many pips. If necessary, that's what resources are for. And the "no error" error occurs when the price is repeated for a modification that already exists. That's why you have to do it step by step, as I advised you at the beginning.

Trawl tries to move SL to the same level. We need to add a check, trawl level should be different from current SL.

I have a check for that:

if (ND(OrderStopLoss() - priceBU * pt) != 0.0)
{
  if (!OrderModify(OrderTicket(), OrderOpenPrice(), priceBU, OrderTakeProfit(), 0, CLR_NONE ))
  {
    Print ("Ошибка модификации ордера ", OrderType(), " - ", GetLastError());
  }

}
If stop - new stop (in b.u.) is not zero... then we modify... If not, we don't modify. That's why it's not clear to me how this happens. After all, I understand that I need to check for equality of past and new stop and I have done it.
