That's the way it is;

enum typ
  {
                        ty1=0,                  //Buy and Sell
                        ty2=1,                  //Only Buy
                        ty3=2                   //Only Sell
  };

input typ               TradesType=ty1;         //Type of trading operations
.
.
.
if(TradesType!=2 && ...
if(TradesType!=1 && ...

Thank you

Good afternoon, colleagues. I can't find an error in the code. The .Magic() method of theCPositionInfo class gives the correct value, if the trade is opened directly in the code through the Trade.mqh class.

If I open a deal through Trade.mqh, but called in another class, then the.Magic() method gives 0 in the Expert Advisor code. Why is it so?

I am attaching the code.

I do not open the code)

So, the second variant does not use Magic, look carefully at the code

I haven't even looked at the archive.

The algorithm is always the following: You create 'm_trade' - object of CTrade class. If you want it to trade by its Magic - you must do

   m_trade.SetExpertMagicNumber(InpMagic);

- That is, you must set this Magic for the object of CTrade class.

I'm doing it the old-fashioned way, I can't get out of it...
