Hi, Below is the standard moving average strategy that comes with the system. Can someone show me how to modify it slightly. I see no profit target, and I'm finding it difficult to even adjust the parameters of of the buying and selling levels.

I assume the two orders at the bottom are for the exits, and the two at the top are for entries.

when I try to make adjustments by adding variables and adding or subtracting points it performs unlike I'd expect, such as no orders at all, or only does sells.

for a test example I'd like to sell when it's under the ma by .0005 and buy when it's over the ma by .0005 and also have a profit target in dollars that I can set. It's also unclear to me if the "Close[1]" is referring to the tick close or the bar close.

I see no difference with the original EA

so what is it you tried to make it work with profit target

and if it is unclear to you what Close[1] means then it is also unclear to me how to explain you what changes you have to make...

Close[].

Close[1] referes to the last price of the last completed bar.
