Basket Of Trades Grid Question

[Implosion]

How do I have a basket of trades in a grid where they are "at market" transactions triggered at a certain pip distance(not pending orders) where I have the same take profit pips based on the last market order transaction? So the take profit moves based on the last transaction in the basket. I also want to increase the lot size on each trade in the basket. Then I want to hedge the whole basket if I run out of grid trades.
