Thank you Petko for your quick reply,
Well Ive already done what you said, my question is: when we attach an EA to a specific timeframe for ex. M1, if on the same chart window we clicked on another time frame ie. M15 the EA detach from M1 and reinitialize on M15, this is what the ecperts log shows, this the way Mt4 works right? Thank you again Petko. Happy Easter.
