Muti terminal interference

[Tyrone Chan]

dear traders,

i have installed 3 MT5 terminals and trade with 3 different accounts with the same EA with differenct magic numbers.

my problem is that they seem to be interfere with each other.

For example, the EA is set to allow only maximum 1 position.  It works fine for using 1 EA on 1 MT5 terminal.

However, it is not okay that when i diplicate the same on another MT5 terminal with a different magic number.  It exceeds the maximum position  to have two positions.

I appreciate you advice.

Unless each instance of your EA is writing to a common external file, I doubt that interference is the case. At the moment, I have 4 MT5 terminals on one pc with no issue. If you want to be sure, reinstall all MT5 terminals in Portable Mode which will isolate them from each other 100%.

"Portable Mode

When installed to Program Files, the platform works in the main mode described above on default. All the platform data are stored in a special Windows user directory. However you can force the platform to store its data in the installation folder."
