Of course. The question that remains is how accurate you would be? You certainly can't expect to win every time, so some times you would react properly, and some times you wouldn't (you would cut profits).

Now when you think more about it, in a way you would manually implement TakeProfit, would you? But then, if that TakeProfit is really more profitable it could be built right into the strategy, so that it is triggered automatically. If it was that simple, don't you think that jcl would built it right into the Z's?

The more I learn, more I understand that lots of ideas look really good on paper, but fail miserably when put to test. The only way you could really measure the effect of your tampering with the strategy is to forward test untampered strategy together with the one where you apply discretion. So after some months have passed, you could see which one performed better.
