I hadn't tried charting either the NDX or SPX using QT and IB's feed since I have them on my other screen using QT with Ameritrades feed. I do have them in TWS right next to the futures, NQ and ES so I can compare them. I'm only trading the ES so far, so haven't paid that close attention to the NQ and NDX. But you can look up the fair value for the futures. SPX was -.25 to the cash today, and you use that as your reference point on whether the futures are pushing or pulling. Then since the cash is only calculated once every 15 seconds, when you see it update, you know you have 15 seconds before it will change again. And sometimes when it changes, the futures will react to it. And then I've been watching the top 10 stocks in the S&P500 to see if I can get a feel on which way the SPX cash will go on the next update. Just trying to see if there is any kind of edge I can get.
Shoot, this weekend I read that the market makers on the futures are using the computers to do their trading for them. So we're really playing against the computers.
And now IB is showing the NDX as 1439.64 and -33.35. The markets are closed, it shouldn't be changing. I wonder if IB is updating it as stock prices change afterhours so then you have an idea where fair value on the futures would be. And the SPX doesn't change since that is calculated and given out by the S&P500.
