What do you all use for tracking the curves in near real time? IB's term structure chart lags behind a day I believe which is kind of annoying. I guess I could build a spreadsheet to download the info into perhaps. I don't mind it being delayed a little, I just don't like getting on at midnight and not being able to see the prior days change in the structure.
I have it real time on DTN Prophet X but IB settlement curves are in fact more useful. Stale quotes on one expiry make real-time completely false...You always have to recheck with previous day settlement. What would be great is one real time curve based on native spreads midpoint but most of the time it is not available...
