communication between EAs - other then with global variables of the terminal ?

[Willbur]

I wrote an EA who will support me in trading (e. g. traling Stops, buy and sell on trendlines and so on).

I apply this EA for each chart which I open.

How can these EA kommunizierien with each other ?

Is there an other way then using the global variables of the terminal?

         GlobalVariableGet () ...-Set().

yes

FileOpen();

and

FileWrite();

or use named pipes.

https://www.mql5.com/en/articles/503

• CreateNamedPipe - creates a named pipe.
• ConnectNamedPipe - enables server to wait for client connections.
• WriteFile - writes data to pipe.
• ReadFile - reads data from pipe.
• FlushFileBuffers - flushes accumulated buffers.
• DisconnectNamedPipe - disconnects server.
• CloseHandle - closes handle.

"named pipes" sounds good.

I am going to try this one.

Thanks

Using named pipes to communicate between code running on the same MT5 terminal is like using a rocket to crush a fly.

You can use Custom Events or files.

By the way, what is the problem with Global Variables ?

At least that sounds like something that has a high success rate

No problems so far.

I was afraid that I can't control whether the variables are always written to disk so that the other EA can read.

After reading the manual, writing on disk does not appear to be necessary.
