Is there A Tool for Setting take profit and stop loss levels of all open trades for trailing purposes?

 

Lets say I'm expecting a 40 percent devaluation of a currency. I want to take advantage of the situation as much as possible with little deposit I have. While Im making profit I will open new trades with the created free margin. If my gamble holds there will be lots of opened trades and it will be impossible to trail tp sl levels.

Just for clearity Im using MT4
Is there a existing tool to assist me in this matter?
