When you see the "smiley face" on a chart.. it means the EA is set to trade. Practically speaking you do not have to do anything else. The EA should automatically initiate a trade when the programmed prerequisites are met.
If you right click on the chart a pop up menu appears, click "expert advisors",
"properties" in.. "common" ensure.. "allow live trading" is ticked, then go to "inputs" and see if is required to type your MT account no. If not..that's all you have to do.
On a D1(daily) chart and even on smaller time frames some EA's could take more than 1-2 days to start a trade. I had such an EA and got rid of it in time.
Thanks Fantomas. I think I was just looking too hard, and think I have it now.
one more question... If I have all the charts where I have either an EA or a custom indicator attached open, lets say I have 5 charts with an EA and 5 with a custom indicator (Auto forex cash) I should get signals when they occur on any one of the charts, right?
