take profit slider -/+ OCO

I love trading with the sliders >>>. I looking to able to select one contract from the slider to Take profit on... when placing multiple contracts ... this would let traders to (TP) on one contract at a certain price levels (and let one ride) or stairstep (TP)'s ((( I believe there is something similar in ninja trader )))

Ps: I believe this would be part of the OCO orders

custom oco bracket ( maybe a minimum 3 custom bracket orders for 50k) (6 for 100)( 9 for 150k)
