I would like to be able to analyse individual ea/trade method performance. I'm not sure if this could be done by magic number or comments. Their are a few spreadsheets and ea's that do this floating around on the web for example:http://www.mediafire.com/file/uocrmg2xlyz/Mt4%20analysis%20sheet%20version%201.0.xlshttp://www.easy-ea.com/analyser.htm
these are just some examples but their are many more floating around on the web I believe that donnaforex has one in her members area.
The features that I would personally use would be
1. tracking individual performance of an ea in a multi ea account
2. tracking the performance individual currency of a particular ea
3. tracking the performance of individual currency of a particular ea with trades taken at a particular time.
I'm sure that people could think of more things to add and I encourage people to do so.
I'm sure that if you added this type of features that people swarm to this service from the other stat sites. As I believe that the developers of this site have done an excellent job so far.
