PLEASE I NEED HELP

[[Deleted]]

I've this code i will pass you, the code, is based in ADX, and has to do 2 things.
First to set Arrows when the ADX make a Cross, and Second to set a 1 Alert when the Arrow is set in the Price Chart.
The Arrow thing is working, but i have the issue that when i try to set up the alerts, i have 2 escenarios the first each tick in the candel it will send me the alert (annoying, if you are using a 5 or biger time fream) and second it only apper the alarm 1 time only but when the next arrow apper it not send the alert.


PLEASE HELP ME, i think is something very simple, but i can't find the answer.

THANKS IN ADVANCES.

Replace Alert with PlaySound. You will know the problem is with Alert function or the problem is in EA logic.
