Add hedge filters to my MT4 EA

i would like to add a hedge counter trade to my mt4 ea my ea has a fix take profit value, i would like to change the value as the trigger value to place a counter trade ( hedge ) rather then a fix take profit. eg: fix tp = 3 ( normal ea will close trade at 3 pips ) - i dont want this to happen i want fix tp = 3 ( trade hits 3pips but place a counter trade - hedge ) fix tp will be called something else Both trade will be trading for X amount of minutes - which is user imputed and closed together.
