performance EA on one chart vs multi charts

 

Hi,

I would like to know how mt4 process EA on each chart.

If I have 2 charts and 1 EA by chart, is MT4 use mutli thread ? or use sequential and do chart by chart ?

I would like to know if it's better to do only one EA on one chart that do calcul and send order for multi symbol or if it's better to do a EA that calcul and send order for only one symbol and attach this EA to multi chart.

thanks

 
Each EA creates a dedicated thread. Prefer to keep it simple and use multiple single-symbol EAs.
