EA only works on one chart

EA only works on one chart
Files:

EA works on that chart it is loaded on... If loaded on EURUSD, it will trade ONLY EURUSD.

I will try myself and see if there is any other problem. 

Raymond Chien:

might you have something for mt4???

i have 4 charts open, 4 different currencies, but it only opens orders on the 1st chart
Use different magic numbers.
should I perhaps change the Symbol() command in the code as well?
