Hi all, I am quite new here. I found there is a forum titled "Prop Firms" but in fact I am not working in this field. I have some questions to ask: Actually, how a prop firm operate? I cannot though of an equilibrium point such that the employees of a firm will stay with the firm. If I were an employee of a prop firm and I could trade with a profitable strategy, why do I stay in the firm and not trade on my own? If I were an employer of a prop firm, why do I trust the employee not stealing the firm strategies and then start up their own one? If the firm risks their own capital for the employee, IMHO, the firm will behave more like a VC than a prop trading group. I google on the internet and found that some firm offer some kinds of service like DMA, low-latency hardware, etc. I guess those firm is working like as a broker (sell side), right? How about the buy side? do buy side prop firms exist and how they operate?
