What kind of software/system prop firms use to control risks? I am about to hire two traders to let them trade unsupervised. I am afraid if some day, some how, one of them made a huge trade without stop loss or he is unhappy about the profit share so he intentionally makes a bad trade to lose money. How do you firms review trades in real time? Even if they trade with me, how do I supervise them? Is TRUST the only thing I rely on here?
