Yedelkin:

Quote from the article: "When connection to the trade server is lost, the terminal periodically makes attempts to restore connection".

What is the frequency of attempts to restore connection?

Every 5 seconds

Another question on the same topic. How does the TerminalInfoInteger(TERMINAL_CONNECTED) function work : does it make an immediate attempt to reach the server when it is called, or does it take data about the presence/absence of connection from the mql5-program environment, which is updated once every 5 seconds?

In other words, can we count on the fact that the call of the TerminalInfoInteger(TERMINAL_CONNECTED) function will return actual information about the current real state of the connection, regardless of the fact that the terminal itself in such a situation checks the connection only once every 5 seconds?

[Renat Fatkhullin]

The function returns the current connection state without any attempts to raise the connection. Reconnects work automatically and independently.

I understand that when the connection is lost, theTerminalInfoInteger(TERMINAL_CONNECTED) function will return the data that was generated after the last 5-second reconnect. Thanks!

No. The function will show the current status of the connection. It has nothing to do with 5 sec.

Oh, I'm having a hard time grasping science today...

It turns out that in case of connection loss the TerminalInfoInteger(TERMINAL_CONNECTED) function will show the current real state of connection but will not try to restore connection. OK, for my purposes this is very handy. Thanks!

How to select history orders/ deals/ position by incremental indexing.

Such as:

    for(uint i = uint(HistoryDealsTotal()-1); i >= 0; i--)
    {
    if(deal.SelectByIndex(i) == true)
    {
    //--my data
    }
    }

Is it possible?

Infinite loop!
