IQFeed still leads the choice for backtesting and real time market feed over Interactive Brokers ActiveTick and others
IQFEED most bang for you buck
I can verify this ?
Qfeed (True Historical Order Flow)
I’m watching the level-2 screen and the level-1 screen on IB and it never seems to match up with the quotes that I get out of IQFeed. IQFeed is definitely realtime, since I’m seeing the prices match up. It’s just that the sizes don’t match up. Which one is missing exchanges, or is one pulling in regional data that’s not the same?
I still think IQFEED is the best for quality and historical. The APIs are really good depsite the extra little bit you pay for. The pro ones are 10x the price!
NOTE I now post my TRADING ALERTS into my personal FACEBOOK ACCOUNT and TWITTER. Don't worry as I don't post stupid cat videos or what I eat!
