Vladimir Baskakov:

Confused about the correct spelling of the condition, help:

There could be two options:

1. "MA Slow" is higher than "MA Fast".
2. "MA Slow" is lower than or equal to "MA Fast".

Accordingly the sign of the result will be "+" or "-". If the sign is "-", your condition will never be fulfilled since "-" will always be less than 5*Point().

In other words, the code will be

   if(ma_slow[0]>ma_slow[9])
      if(ma_slow[0]-ma_slow[9]>5*Point())
        {

        }
   if(ma_slow[9]>ma_slow[0])
      if(ma_slow[9]-ma_slow[0]>5*Point())
        {

        }

Exactly! The second condition I was thinking of doing that too ;) Thanks

Maybe you posted the decompiled code? Maybe you asked for something else to do with decompiling the executable?

No, the questions were about translating code from mql4 to mql5
I did everything, but there was an error while working, I asked for help to figure it out

Strange. Was there a code? Maybe there were signs of decompilation in it?

I can'topen a position, I get a wrong volume response for any values.

   if(direction==0)
      open_label=open_label+"Buy  "+ "V = "+DoubleToString(V,2)+" price = "+DoubleToString(price_open,_Digits)+
                  " SL = "+DoubleToString(SL,_Digits)+"  TP = "+DoubleToString(TP,_Digits);
   else   
      open_label=open_label+"Sell  "+ "V = "+DoubleToString(V,2)+" price = "+DoubleToString(price_open,_Digits)+
                  " SL = "+DoubleToString(SL,_Digits)+"  TP = "+DoubleToString(TP,_Digits);
   
    Print(open_label);

   if(direction==0 && last.ask<=price_open)
      {
        if(!trade.PositionOpen(_Symbol,ORDER_TYPE_BUY,V,price_open,SL,TP))
          Print("Метод PositionOpen() потерпел неудачу. Код возврата=",trade.ResultRetcode(),
            ". Описание кода: ",trade.ResultRetcodeDescription());
        else

Hi guys, can you tell me how to calculate the commission for open trades in mt5 volume or tell me where there is a ready-made function

PositionGetDouble(POSITION_COMMISSION)

Or CPositionInf Commission

Konstantin Nikitin:

Or CPositionInf Commission

Hasn't been working for a long time.

fxsaber:

Not working for a long time.

I've tried it and your function works fine. Anyway, thanks a lot for your feedback,

I've got it figured out where to get the commission)) I'm new to MT5 so I'm not too keen on it, but I'd better check it if it's not right

i think i got it right
