"Everything is working great ! Very impressive client. The news refreshes better and is more pertinent than the ******* feed I paid $ 100/month for. I Also like the charts a lot." - Comment from Leon
"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum
