Develop an ea that automatically disables and enables other ea's when one ea is trading.

I have a couple of copy trader expert advisors on my account that are copying trades to my account, each copy trader ea is copying orders from a different account. The problem is that if two copy trader ea's will copy at the same time trades so my account can explode because my deposit load can be very high and also my drawdown will be very high. So I asking to create for me an ea that will disable all of the other copy trader ea's when one copy trader is copying trades. for an example: I have "copy trader 1" "copy trader 2" and "copy trader 3", if "copy trader 1" opens a few trades, let's call them "trade 1" and "trade 2", so the ea that I am asking to create for me will disable "copy trader2" and "copy trader 3" until "trader 1" and "trader 2" will close. It is important for me to say that the copy trader that opened the trade will continue working while it's trades are open, so if it will want to open another trade while the first trade is open so it should still be able to open more trades, I only want the other copy traders to be disables while one copy trader is trading, but I want the ea that is trading so stay enabled. Last thing that is important is that when all of the trades close so all of the copy traders will automatically get enabled.
