mdmbud, the reference of fre data wasn't to you, there are a number of threads where people are asking about free data.
I have been with Qcharts for three years. Early on before the server farm rebuild, the feed was pretty spotty... . Now it is very reliable. And user friendly. I use the Qlink DDE for running ideas on Excel.
ES traders - recently I have been working on some ES daytrade ideas. I first noticed a problem with opening bar prices on the 1 minute chart when tracking Quah's method. Then again while chatting with a friend and watching the ES his opening ticks were different than mine a number of times. I called the CME to see who was incorrect and it was always Qcharts. So I emailed QCharts and they said they were aware of it and expected a solution in the next thirty days. This was about two weeks ago.
