Show/Trade from average of positions in MT4?

Hi all, been a lurker around here for a while and have a quick question that my searches have not been able to answer for me. I have traded on OANDA for a bit and like the ability to show the average position of all of my trades for a given pair, as well as the ability to set my TP/SL for all trades based on this average position.

That being said, I haven’t found anything like it in MT4. I know it’s not included but is there an EA or something that might provide similar properties to my MT4? Thanks in advance.
