IB historical data - how accurate for backtesting?

Discussion in 'Data Sets and Feeds' started by itmediaco, May 30, 2006.

  1. I'm using Wealth Lab, which Fidelity claims to have the cleanest data but their commissions are too steep for automated trading. I have an account at IB as well, and demoed Wealth Lab Developer with an IB data adapter. Needless to say, both feeds are inconsistent (IB is actually more profitable with systems tested). I haven't made actual trades with either at this point.

    Anyone here use IB data for backtesting systems and real time trading? I'm interested in your feedback. Thanks
