Quote from daniel33:
If you are serious about your trading I would not rely on IB data for serious daytrading.
Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES.
Hurts to pay the fee but better be safe than sorry.

I'm very serious about this full-time profession and have never had issues with IB data until mid-Sept (Globex backfill). I'm also a DTN/IQ subscriber for backup data purposes. If you are serious, not sure why you'd have to justify a measly $120/month backup feed incase something goes wrong with primary.
IB realtime data is of higher quality than IQ from my experience. Notice upwards of 5-6sec lag with IQ compared to IB real-time during high market activity. IB order execution has always been top-notch. Their customer service sucks.
