I stick with the strategies on M15. Why would you try to go for more difficult trading when the simple one works fine.
In Jan and Feb I have unseen results so far. In March for 10 days, I am over 1000 pips. Al of my EAs are on M15, so I would not change a thing.
I know many traders are enthusiastic to create EAs with what they used to do before EA Studio, but that is wrong.
Look at the results the software gives you. Run a couple of generators with the same acceptance criteria on different time frames and see where you get the most profit. That’s it.
