Additional method of closing trades with a total break even (finding combined profit break even level for all open trades)

I have an EA that is looking very promising but sometimes has trouble closing trades in some conditions.

It opens trend following and counter trend orders, sorts them into groups and closes them when passing a certain way past the group break even level. but only groups of either all buys or all sells.

Sometimes while watching on the tester I can see obvious places to close a group or even all open trades. but they are not closed and can go on to cause problems later on.

I want to try an additional method of closing ALL open orders where after a certain number of trades are open and active, the combined break for all buys and all sells is calculated and a take profit level is placed a set amount from the total break even, the take profit is then used to close all trades 

as always, I have entered a price and time because I cant post the job without doing so, they are both open to discussion.
