difference in ECN charts

 
In The ECN platform there are ' normal' charts, Avg and Ask charts. There must be a difference between them, so which one, avg- ask, can give the best results for an expert advisor?
 

No such thing as a MT4 ECN platform. There is one platform. ECN refers to the broker.

There is no such thing as normal, Avg or Ask charts. All charts are Bid charts. (only offline charts created by a program show anything else (Constant Range bars, Renko, tick, Ave Bar charts, etc.)
