I know to avoid the ones with dealing desks ?who are usually market makers?
Then I was trying to find one which was a "true ecn"
MBTrading looks really good to me and the guy who calls me says they're an e
xn broker which is "the same thing".

MBTrading seems like a really good broker to me.. the service is amazing thus far
Then, IB looks good too... and they tell me this: Interactive Brokers is considered a direct access execution firm, therefore, we are neither a dealing desk, nor an ECN broker.
