I need and EA expert to code a very good and profitable system

[ivancho]

Anybody else who wanna try to create an EA and share it with us?

Well… I’d certainly not say that I had “difficulties” to code the system. I will assume in the OP’s favor that English is not his native language.

However, he had a point insofar that the system coded was indeed not identical to the system that he wanted. I used the TA-LIB SAR and he used the MT4 SAR, and I just found that both SARs are not identical. This is not the first time, MT4 uses different algorithms especially for recursive functions - the ATR has the same issue - so be warned when you compare MT4 indicators with other platforms!

Unfortunately the system is still unprofitable even when I use the MT4 SAR.

I think you should set the trade as each bar rather than each tick.

And to say this, the system based on rather easy indicators rules,chances are slim

That’s right. BTW, trades were entered at each bar, which is the default with Zorro.

When you develop automated systems, you learn pretty soon that MACD, SAR, EMA etc. are just a different way to look at a curve and have no predictive power. I could have told beforehand that such a system will not be profitable, no matter how you tweak the parameters.

A profitable system must evaluate properties of a price curve that are not obvious, for instance its frequency spectrum. That’s where profits with automated trading are possible.
