NEED HELP : ERROR array out of range in 'EA name' AND uninit reason 8

New comment

Hello I start in the mql4 code and I want to understand why my small program does not launch while the compilation shows no error!

(I’ve been stuck for 3 days)


Goal of the program:

Alerts the user that the stochastic oscillator of the M15 M30 H1 H4 timeframe of a symbol is on purchase or under purchase. The user can choose to set several currencies to be checked.


Here is the information MT4 sends me when I load the robots on a chart:

This is the script
