O-Yama:
Post, then let's see what's on the server.

I collect the query message array with my function in small chunks, as StringToCharArray behaves strangely and constantly truncates the array. Maybe I messed up something in it too...

void OneMoreString(string str)

{

char cashe[];

int sz=ArraySize(buf); //buf is outside the function, and is always used in webrequest

StringToCharArray(str,cashe,0,StringLen(str)); //convert the string at the function input into the char array cashe

ArrayResize(buf,sz+ArraySize(cashe));

ArrayCopy(buf,cashe,sz); //copy cashe into buf

}

P.s. : I don't know how to insert code snippets here correctly

First determine which side is the problem to fix it.

The code is like this:

Hello all, I can't load the history of deals for any period except one month, I've tried everything, reinstalled the terminal completely, nothing helps. I have tried everything, I have completely reinstalled it, nothing helps. What happened when I have applied an old template to the price chart, as a result all deals have disappeared from the chart and the history has lost October deals, just pipsqueak. Maybe someone has faced with such a problem please help, the Internet also had no answers. MT4

Good afternoon. Can you tell me how to determine the number of open positions for each currency pair and display it on the chart? If positions are open on different currency pairs in different quantities.

The iExposure.mq4 indicator is supplied as standard with the terminal

Good afternoon.
Can you tell me please. Why in the indicator when searching bars, the indicator starts all the time since August 2020. No matter what parameter i is set, i=500 or i=10000000000.

The overshoot begins 100 bars before the current day. On the D1, this is just August. The parameters do not affect this number.

Hello, I have a problem.

I have hieroglyphs instead of Russian letters.I tried changing the regional settings, but it didn't help. Do you know any working methods?
