I have already given you the code to remove the exp from the chart. Since there can only be one (per chart), calling this function with its own handle will cause the exp to delete itself

FAQ:

...to give a command to himself to be removed

Thanks, it works.

P.S..

#include <WinUser32.mqh>

[Рустам]

It goes without saying. When working with imported functions, remember to connect exports from the relevant applications.

Help, why isn't it working?

Thank you.

  int NowOrdersTotal = CountTrades();

    return(0);

  if(UseSound == true && NowOrdersTotal < PreOrdersTotal) {PlaySound(CloseSound);}

FAQ:

Close your window, give yourself a command to delete...

PostMessageA(WindowHandle(Symbol(),Period()), WM_COMMAND, 33050, 0);

So, MQL4 does not provide a standard way to terminate the Expert Advisor. Only through a direct use of Win32 API.

Got it, thanks.

Library. Lots of useful functions for MT4 management. Including removal of the Expert Advisor is there.

Took a look (so far in a cursory manner). Wonderful library!

Thank you!

Good afternoon.

Order modification works partially, help me to figure out what the problem is.

Code and log attached. I have written in the log what works and what doesn't.....

void AllSellLockBuyModifi()
{
 double sell_sl = 0.0;
 double sell_tp = NormalizeDouble((AllAvP()-TakeProfit*Point),Digits);
 int spread = MarketInfo(Symbol(),MODE_SPREAD);
 double lock_buy_tp = NormalizeDouble((LastSellLockBuyAvP()+TakeProfit*Point),Digits);
 double last_sell_sl = NormalizeDouble((lock_buy_tp+spread*Point),Digits);
 double lock_buy_sl = NormalizeDouble((sell_tp-spread*Point),Digits);     
 Print("AllAvP = ",AllAvP()," sell_tp = ",sell_tp," lock_buy_tp = ",lock_buy_tp," last_sell_sl = ",last_sell_sl," lock_buy_sl = ",lock_buy_sl);
 for (int i = 0; i <= OrdersTotal(); i++)
    {
     OrderSelect(i, SELECT_BY_POS, MODE_TRADES);
     if (OrderSymbol()!=Symbol())continue;
     if (OrderSymbol()==Symbol() && OrderMagicNumber()==MagicNumber)
     if (OrderType()==OP_SELL)
       {Print("Find Sell Order");
        if (OrderOpenPrice()==!LastSellPrice()) sell_sl = 0;
        if (OrderOpenPrice()==LastSellPrice()) sell_sl = last_sell_sl;
        Print("Мод-ция ордера SELL № ",OrderTicket());
        OrderModify (OrderTicket(),OrderOpenPrice(),sell_sl,sell_tp,0,CLR_NONE);
        error=GetLastError();
        if (error != 0) Print("Мод-ция ордера SELL № ",OrderTicket()," ошибка № ",error);
       }         
         else 
             { Print("Find BUY Order");       
              if (OrderType()==OP_BUY)
                {
                 Print("Мод-ция ордера LOCK BUY");
                 OrderModify (OrderTicket(),OrderOpenPrice(),lock_buy_sl,lock_buy_tp,0,CLR_NONE);
                 error=GetLastError();
                 if (error != 0) Print("Мод-ция ордера LOCK BUY № ",OrderTicket()," ошибка № ",error);
                }
             }
    }
 return(0);
}

For a start, correct these lines:

for (int i = 0; i <= OrdersTotal(); i++)
    {
     OrderSelect(i, SELECT_BY_POS, MODE_TRADES);

on these:

for (int i = 0; i < OrdersTotal(); i++)
   if (OrderSelect(i, SELECT_BY_POS, MODE_TRADES))
    {
