I have experience in Fxdreema since 2016 and it is the one of the times I fell.... The flow is so simple... nothing to remove.
Maybe somebody could exchange some other ideas.

In the comment Yes, but does not affect the IF statement

Coding is not my best. Even with Claude the result will be the same. For my problem there are several solutions but the question is how to implement it in Fxdreema?

I try to control EA with CSV files in MQL/Files/settings.csv

The file contains only one value 0 or 1. If the value is 1 = sell trades enabled, 0 = sell trades disabled.

Now it is in a research mode that's why the csv filed is read each tick.

How to set the 'custom MQL code'? I did something with GPT but not works. My variable is: 'sell_yn_var'

This an example project - https://fxdreema.com/shared/Q8uwhrIY

Thank you
