What about making Expert working on another chart?

[Ahmed Abd El Aziz]

Hello

At MQL5

What about making Expert working on another chart?

for ex: running my expert at (EURUSD chart M5 timefram), and it must opening all positions at (EURCAD,EURAUD....,15M,H1 ....etc)

Is this possible ?

How can i do this on this code:

// ----- > column_table < ----------

// $name = name symbol .
// $stimeframe = time frame expert // example  ( eurusd, 15m ...)
// $section = ادخال يدوي
// $stitle = ادخال يدوي
