Hello Riuzk,
that is available in FSB Pro for sure. There is an indicator called Days of the week. It allows you to use the EAs only the days you have chosen, or the days the generator selected.
I am not sure if it is possible with EA Studio.
If not, you can just stop the EA on the day you do not want to do trading.
Anyway, even it is available in the EA Studio or FSB Pro, it matters when you create the EAs. If you want to eliminate someday after you see result and stats, it means you have to change it in the EA itself.
For me, the easiest would be to stop the EA for that day.
