But the question is why is there no access to

???

Yes and to

и

???

and why separate access when their values can be defined via define ???

think of it as a pragma in C/C++ - an instruction to the compiler

This is additional code, not quite good, you need direct access.

Now I have it like this (hint from forum), but I'd like to avoid define

#define    release   "1.15"
#property version release // release уже можно прочитать в программе

property can be put to each file individually (i.e. repeatedly and in different places), they have different scope than defines and variables. They are handled a little differently.

I don't see a logical method to move a property to const variables or defines. Backwards, yes, but not there :-)

Can you give me a trick (maneuver) to force the terminal to remember multiple values?

For example, a task:

Given N candles backwards. Find candlesticks with size >= X pips, memorize their number and size of each of them. If the current candle after closing is >= X pips, then compare its size with the total number of calculated candles and print the result - what is its size among all the candles found.

The terminal remembers everything... the quotes archive!

And for the Expert Advisor or indicator you need this

Fast235 #property version"1.07", no such possibility? program name is there, why version is not there as well?

Define and assign the version in the code. No cheaper option.

I can't understand why there's an endless spell here

int GetMagic(Order &order)
{
  int magic = 0;
  //Если должен быть открыт стопордер и если есть уже открытые или отложенные 
  //ордера, то возможно некоторые с маджиком, это надо проверить и сгенерировать 
  //для нашего ордера уникальный маджик и отправить его на запись в массив
  if(order.cmd == OP_SELLSTOP || OP_BUYSTOP)
    if(OrdersTotal() >= 1)
      for(;;){
        magic++;
        for(int i = OrdersTotal(); i > 0 ; i --)
          if (OrderSelect(i, SELECT_BY_POS, MODE_TRADES) != false)
            if(magic != OrderMagicNumber())
              return magic;
            
      }
    //Если нет открытых или отложенных ордеров то увеличиваем значение 
    //маджика, чтобы он равнялся единице и отправляем на запись в массив
    else if (OrdersTotal() == 0)
      return (magic + 1);
  return magic;
}

I can't figure out why there's an endless spell

is this a joke?

You have it in black and white for(;;)

[EVGENII SHELIPOV]

Good afternoon.

Can you please tell me what function OrderSwap() is which returns the swap value of the currently selected order.

What if there is a grid of orders?

Does anyone have a function to calculate the sum of all swaps of a grid of orders for a magic order and a financial instrument.

Thanks for the help!!!
