Quote from dandxg:
Any broker with TT/X Trader. I you are trading 100 lots, why not go with the best.? No offense IB fans, but I highly doubt Paul Rotter or any other heavy hitter uses anything, but TT. I use Ninja with TT data, but at that size I would use TT Pro. A place to start, that I have heard is very good, is Advantage Futures. I use Velocity, they are very good, but just lost one of their main tech guys. IB is great for all around trading. I believe that is their speciality. Good luck.
