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...
Hmm, I believe there is a way to connect IB into excel. Maybe it could be charted in there based on the native spreads like you said. I will see if I can figure something out on it
Indeed you can with DDE links but its a pain in the ass to look for every IB contract number to create a "combo"...
Just saw this post and realized my order filled after all. I entered at .05. Wasn't too thrilled I am going to wait for a bit, but I won't let it move much against me before stopping out.
So I guess it is the same as Prophet X, intraday it uses stale quotes which results in false curve...
Short Mar/May 16 Cotton @ -0.17 on seasonals Short Oct15/Mar16 Soybean oil @ -0.53 on seasonals Short May/Jun Milk @ 0 on a curve play. On any of those spreads I wasn't able to get even 1/2 of the desired position. I guess they will be good trades...
