Intraday Prices Not Posting Cotton Calendar Spread

[plpope]

The attached screen shot is for a cotton spread and was taken at 2:21 p.m. CDST today (11/1). As you can see the latest price is -.36. I got stopped out of a long position for this spread at 11:47 a.m. this morning at -.18371, which is near where I believe this spread closed. I realize the intraday data is not real-time, but I'd expect it would have gotten updated within 10 minutes or so. Here's an example where it's not updating at all. Please advise on what's going on.

Thanks
