Hi Old Guard, I have that prop. firms can be divided into 2 categories.
Category1. Broker- Dealer prop firms like T3 capital, T3 live, Integra Capital ( whose broker delaer is T3) Avatar securities etc. NY alone has around 30 or so firms like these. They basically provide you 1 to 10 to 1 to30 leverage and you are allowed to knock yourself out as per your method. Majority of traders with little or no money get excited by the leverage and are out in matter of weeks to months.
These firms have nothing to loose. They charge you feees for data, platform plus get rebate from exchanges.
category 2. SMB capital, First NY securities ( one of the best). Peak 6 and many others do not take capital from traders. If a trader does not have proven trading record, you apply as a Trader Assistant/ Trainee and start trading after couple of months of training. You want this training regardless of what a trader think how good his/her method /system is.
These firms primarily take traders with strong math, stats back ground. Make sure you check out examples of test at

For experinced traders with record- sky is the limit. They roll out RED CARPET. Ideally category 2 firms are the one one should strive to get in.
Good Luck
