Hello everyone

im trying to practice coding , so i took the code from an old EA posted here and tried to modify it for another indicator
but something in the logic escapes me, and right now the ea only buys and doesnt sell , and when it buys it does so every bar.

I cant understand how to put the logic into code since im a newb.

If anyone would be so kind as to help me , that would me much appreciated.

Thank you very much
