I'm funding a few traders right now. Currently with IB trading futures. My problem is there really is no way for me to set a hard loss limit each day. With IB I can limit size per account but that's it. Considering there are so many trading firms out there I'm sure there are brokers and platforms that offer this functionality since it is essential for a prop firm. Having blown a few accounts myself throughout my career its my biggest fear for my traders. So far from my research I know rithmic as an auto-liquidate feature but it is set only at the broker level and there is a fee each time its activated. I would like to be able to set it myself for all my sub accounts. Any platform provides this feature? How do prop firm's manage risk?
