i am kinda confused. i am new to daytrading. i just plan to trade remote using my own money. what is the difference between using a broker like IB and those "prop firms" like genesis/jc that offer rebates?? wouldnt those "prop firms" be just brokers but offer ecn rebates? or they charge you some other fees ? assuming i only make 5 trades (1000shares each) each day, doing nyse, which kind of brokers will be cheaper? please help
