Quote from ElectricSavant:
I thought in Prop trading you could lose no more than your 5k or whatever you put up? If that is so, would the Prop shop allow you to continue to trade into the negative or would you need to put up some more money?
But Don, the difference is that if he uses your capital and loses more than what he put up, he'd owe you money...
Is this correct, would the trader owe the company more money than he put up in the beginning?
