I'm interested in hearing recent opinions/experiences with Dorman Trading. I plan to use NinjaTrader to daytrade the ES. I make about 2-4 trades a day so I'm not a high volume trader. How would they compare to IB in terms of commission, customer service, data feed, and reliability and reputation as a firm? Would you recommend another broker instead for trading index futures with NinjaTrader? There doesn't seem to be too much information about Dorman. Thanks in advance.
