     if(PositionGetSymbol(i)==Symbol() && PositionGetInteger(POSITION_TYPE)==POSITION_TYPE_BUY)
     {
      if(PositionGetString(POSITION_COMMENT)=="Buy_A"+string(i+1)) //if I add comment get, it includes closed order
      {
        ArrayResize(BuyOPrice,i+1,0);
        BuyNum++;
        ArrayResize(buy_ticketnum,i+1,0);
        buy_ticketnum[i]=PositionGetInteger(POSITION_TICKET);

In MQL5 you can't compare strings by '==' you have to use; https://www.mql5.com/en/docs/strings/stringcompare

I recommend learning the basics - so as not to confuse "order", "deal" and "position": Basic Principles

You didn't read the documentation well and you are using the functions for the NETTING account.

Here's how to do it:

    ulong takeOrder=PositionGetTicket(i);
    if(PositionSelect(Symbol())==true)

You get a ticket from a random position (any chart) but then select a position on the current chart.
