I have an EA that I would like to trade on multiple currencies as well as instances on the same currency (e.g., EURUSD and EURUSD1). Each instance would be the same EA with different settings. This must be achieved with only one user interface so it could be one EA which is attached to one chart or it could be some type of custom interface that uses many different .ex4s with different settings. What matters is that the user has a simple solution that needs to be attached to only one chart and that is very simple.
I've seen this done very easily in the past and am interested in your ideas so please message me with your solution.
