When I started reading about trading, I read about brokers, and the first ones I knew where thinkorswim, IB, Speedtrader.com, and some others. These ones seem to be good, but as far as I know retail brokers are for people with 25K or more right? So I have several questions: 1. If you have 100K why would you still use a proper firm instead of a retail broker? 2. I heard that one difference between them is that prop firms have DAS which means that orders go directly to the execution floor, and retail brokers, the order goes first to the broker, and then to the execution floor, is that a big difference? 3. When researching prop firms, whats the homework I should do?, In another post somebody asked me to request a focus report but international prop firms dont have it, I dont even know what a focus report is lol!!! And the last question, which prop firms do you recommend, and which ones, you dont?
