Isn't it time to merge all the MT4 help threads into one?

Renat Akhtyamov:
Isn't it time to merge all threads about MT4 into one?

Each author has his own branch. It's just that one author runs it and the other author doesn't and won't. It's just a place for those who want to help. Why would I want to shove my branch into a branch of an author who is not going to help me with mql4?

Artyom Trishkin:

and I think so, too.

Hello.

Where can I find the language description for MT4?

Hello.

Where can I find the language description for MT4?

In MetaEditor on F1. Or here, same thing, but online. You can also google books on C++.

Hello.

Help me find the price of the last order.

This function finds the price of the oldest order and I need the youngest one.

What to change?

double GetOrderOpenPrice(string sy="", int op=-1, int mn=-1) {
  datetime t;
  double   r=0;
  int      i, k=OrdersTotal();

  if (sy=="0") sy=Symbol();
  for (i=0; i<k; i++) {
    if (OrderSelect(i, SELECT_BY_POS, MODE_TRADES)) {
      if (OrderSymbol()==sy || sy=="") {
        if (OrderType()>1 && OrderType()<6) {
          if (op<0 || OrderType()==op) {
            if (mn<0 || OrderMagicNumber()==mn) {
              if (t<OrderOpenTime()) {
                t=OrderOpenTime();
                r=OrderOpenPrice();
              }
            }
          }
        }
      }
    }
  }
  return(r);
}

Well, that's the latest, that is, the newest

That's how it determines the price of the last order.
