How would you describe the rules though, mudar?
I really have no set rules myself.
I mean it must take a very clear understanding of things before doing an EA, right?
Well here is my description as I write:
We only open positions in the direction of the cross of yellow and white lines of the bottom indicator (period of which should be 3-5 times longer than the original chart, I use 150 minutes when trading on 30m chart). If yellow higher than white we only sell and vice versa.
Signal for opening position is metatrader's MACD cross of the zero line (same thing as (E)MA cross, actually) with period.... 10 and 15, or 13 and 34 - my favourite settings, surely other can be used.
JMA can be used for adding to the position.
But you see, there are things like support/resistance, trendlines, price speed, and you cannon formalize it into an EA. At least I have no idea how it can be done. I don't think so.
But yes, if you want to give it a try, please do. Please share with us your results.
