Use QT only for the Time&Sales strip fed by IB's 250ms aggregated data. Don't like reading raw ES T&S trades.
As confirmed above by DTN, IQFeed continues to stream aok without QT registration.
Have had a lifeless TDA account for 4+yrs now, with peanuts sitting in there collecting dust (~ $50). Wired over $2k in anticipation of registering QT. Bought some LQD (corp bond) with the funds.
Funny enough, before the wire even hit TDA, was able to successfully register QT and use IB feed. In hindsight, should have just tried that route first instead of going through the aggravation of driving to bank. May even transfer the $2k funds back to my active & preferred brokers (IB/MFGlobal).
So for those of you with lifeless TDA accounts with minimal funds, you'll be good to go with regard to QT.
