Ok so I have found an indicator that I really like and have done well with. Im trying to make it into an EA but am having trouble. Very basic. It is an double EMA cross, so you would think that it would be easy to code. The code that I have taken from other EAs and put together isnt making every trade that the indicator is taking.
I want it to enter when the 55 and the 13 EMA cross on the 1H chart, then close when the it crosses back but on the 30 Min chart.
Im going to place the indicator code and the EA code. The indicator has been way more accurate then my EA so that is what Im trying to mimic. If you can help I very much appreciate it.
Thanks!
