Be able to set your PDDL in the money so that i could set it for a profit and not lose all gains.

I would love to see a sophisticated PDDL that I can change as I make money in the market so that if I make $1000 I could set my pddl so that I dont let my account go below $500 in profit and I can still get stopped out with a winning day. Just would be insurance that I don't get caught up on tilt and lose my winnings.
