Man, you really do not need such an OFF/ON option. Why will you place indicator in a strategy and then select OFF??? Give me one reason for that and I will agree with you :)
I do not know from where you took that picture but I am quite sure it is some quite smart guy who is selling Expert Advisors and he shared just some pictures…If this is the case do not bother trying to imitate his strategy because most probably it is not profitable in the first place. He is just selling it…
