I have a strategy that I've traded successfully for several years (I was previously with a large bank). The problem is that it is very high frequency and the commission eat away a lot of the profits now that I am paying retail commissions. I'm considering going with one of the Prop Firms that offers $0.30/1000 shares which would be a huge savings from what I'm paying now. My concern is that it will be fairly easy to reverse engineer my strategy if they want to, once they see the profits it is generating. Perhaps I'm paranoid, but regardless I've been searching for a larger broker that offers 'trade one symbol all day for a flat fee' but still allows me to plug in automated trading via Multicharts or Tradestation or that offers very low commissions for high frequency traders. I currently trade with IB and like the system and commission are reasonable for retail, but very high when doing 50 or more round trips a day. Thanks in advance!
