Quote from AAAintheBeltway:
Agree and disagree. You are right that it is very foolish to try to save money on a trading tool. One trade that goes sour because of a problem pays for a year of a better feed. But I'm not sure I agree that other feeds are so much better. TradeStsation has plenty of problems, as does RT. I'm not impressed by the limitations of esig. Any internet feed will have issues. I used a sat feed and guess what, they have problems too, only they tend to be the kind that shut you down for a while.
I use QCharts for charting futures and indexes and to watch the hotlists. For that I think it is pretty good. I don't think I would want to trade off it by itself, but if you can compare prices to a broker feed like IB or Hammer, I think it is as good as any.
