I am an active trader for 5 years with my own daytrading accounts at Tradestation, Interactive brokers, MB trading, and Ameritrade. Play with two directions, buy and short. Very profitable. Beginning from this year, it becomes harder and harder to get chance to short stock at the retail brokers. I am now looking to switch to Prop firms that can provide me chance to short any stocks I want. I don't care high cost as long as the prop firms can locate hard shorts for me. Do anyone know if there are such prop firms existed? Thank you for your advice!
