Thanks OT,
I will take you up on your offer.Ami is great program,but is in desparate need of a simplied" Dummy" manual for those that have very little programming experience.
As I did not write this code,and was using it to learn "AFL",I am having a difficult time pinpointing what is causing an 86% scale out,when it should be 50%..
If there are any power users who have a simple code that involves "scaling in/out of positions"and replacing stops,or a pyramyiding example would really appreciate seeing it.
