You probably don’t want to hear this but as a system creator I wouldn’t meddle with a system. If you meddle with a system you will most likely not do as well over the long term. A lot of people on C2 lose money despite the fact trading is automated in generally profitable systems. All people have to do is leave subscribed systems alone to operate, yet somehow humans find it difficult to do that. I can guarantee you are smarter than some automated system, and you probably have a wider view of the market than the system, etc… however that doesn’t mean you will perform better than the system. In reality it usually means you will perform worse.
You’re paying someone to manage the trade, let them do what you are paying them to do. Your account balance will thank you for it.
As for your comment that adding to a trade that is already profitable is a bad idea, that’s simply wrong. Many kinds of trades have a higher expectation when added to after they have gone up somewhat; also many sorts of trades will have a reduced expectation if added to after they have fallen. Unless you’ve done the testing you cannot make the general statement you are making.
