" and my balance become 0 with in 3 month with other two model testing. What should i do ? Another question is what is modelling quality mean ?
I hope you guys help me. And post your suggession. Look iam new programmer so donot hegitate to post ur comment. English is my secondary language so please ignore my spell mistake.

There are extensive artices on the mql site (http://www.mql4.com/) on this subject, there is no simple and easy way to sum up the differences.

your system has to survive every tick model, too. it's the closest to reality.
