Thanks for your answer.
I did try using loop thru open position but it seems unreliable for me. I'd like the idea of comparing open position before and after trade, however i'm bit confuse on what block to use. I tried to check the "Check Trade Count" block, but i don't know how to store the value of the trade count after using that block

Thanks to the fxdreema community, I am refining the EA.
Soon I will share the final version for those interested.
