No, ... no third party feed here. Never have during the three years ive been with IB. No data fees for me. Most of my work is with index futs -- scalping or scalping a position and sometimes a few stks. I use ZLT to trade. Hooks up to IB's feed just fine and very fast...my latency is abt 72 ms. from SW of Houston. Also use QuoteTracker with this feed--works great. rj
IB's high frequency sampled data feed is fine for most retail traders. Traders that need a true tick feed have to go 3rd party.
