I can set Moving Average Levels on my charts in the dialog box settings,
so how do I program the MA Levels into an EA lines of code?

To Buy when Price is between the MA Level values of up +20 and +40.
To Sell when Price is between the MA Level values of down -20 and -40.

How?

If you post the indicator mq4 file, I'll tell you if it's possible. Are you trying to do this: http://forum.mql4.com/23815? If so, go here and download the MAChannel indie: http://www.forexfactory.com/showthread.php?t=92106. Specify each Pip_Offset +/- MA in the inputs and set TA conditions accordingly. Multiple TA's should function as multiple bands if set properly. Offsets are actually in points, not pips when used with 5 digit pricing. It's hard coded as an SMA (0), so if you want EMA(1), SMMA(2), etc. you will have to edit the MA type in MetaEditor.

You are right.
I copied my questions from "http://forum.mql4.com/23815" and pasted here.
I appreciate your help.

A Level, when used in MT4 with a iMA, is nothing more than a prescribed distance from the iMA itself. I believe that in MT4, the Level's line is draw at a ratio of: 10:1. So, if you set a Level on the iMA at say +400, then you are really saying that you want to draw a mirrored MA with a distance of 40 pips above the real mode iMA. Consequently, setting the level at -400, puts the mirrored MA below the real mode iMA, at a distance of -40 pips.

I have another post that will address something similar. I don't want to steer this one too far off its intended course.
