Expert advisor removed from the chat after loading

New comment
 

Hello,

I am a learner and have been practicing on how to create EAs. However I have encountered a problem where my EA /alert system is being removed from the chart 
immediately after loading.

Can someone explain to me what could be the problem. PS. I have tried similar code with different RSI or ADX but for CCI its not working.

Can someone please help.

The knowledge of programming languages is no longer a prerequisite for creating trading robots. Earlier lack of programming skills was an impassable obstacle to the implementation of one's own trading strategies, but with the emergence of the MQL5 Wizard, the situation radically changed. Novice traders can stop worrying because of the lack of programming experience - with the new Wizard, which allows you to generate Expert Advisor code, it is not necessary.
