I use eSignal, IQFeed, and IB and they all work fine here. Streaming 100 symbols is not an issue at all. They all can do that perfectly fine. The difference is with speed of backfill and that's all.
Getting impressions on mailing list may be very misleading. Out of many thousands of users there are *always* few who have problems and they of course speak up. It is perfectly normal. Everybody who is doing fine is just quiet because "it works OK" is no news and nothing to talk about.

I have been using QuoteTracker (1 min updates with some 75 symbols) and have never seen any delays or problems. I also have not run any explorations nor scans but just have looked at charts over bunches of symbols. However, I abhor the fact that QT, being fed from my free Fidelity.com data stream, cannot back fill if it misses even a short time much less a day or more (power outages, etc). And I have had a bunch of those recently rendering any signals based on say 5 or 10 days lookback to be worthless. Hence, my search for something with backfill capabilities. I have been considering subscribing to qpFeed, a somewhat new service from QuotesPlus, and then I have seen these numerous messages about slow delivery of 1 minute data from IQFeed but several msgs mentioned qpFeed. So, hence the subject line....what is the best VALUE for the fastest, most reliable intraday, 1 minute (I don't care about tick data and could probably get by with 5 minute data) data feed. I would like to have a universe of ETFs (maybe 100 to 125 symbols) and would like to scan for setups and buy/sell signals on 15 minute charts, maybe even 30 minute charts. qpFeed sounded economical (good value) but if there are major bottlenecks, then I dunno. TJ says all intraday feeds slow down, but what do those intrepid day traders use? Advice and suggestions, please. Thanks. Ken
