Ok, here's a few things that I've found, but this has to do with corn options that trade during the night. I'm including 2 snapshots of a corn option chain from eSignal and Interactive Brokers both taken at 6:15 am EST
The 340 calls are offered at 49 cents with IB showing it in the ask column, but eSignal doesn't show it. The 310 puts traded 3/4 on 9/27 at night as IB shows the trade, but eSignal still shows it as being offered there at 3/4. These options traded because I traded them! The 460 calls are bid 1 cent for 100 lots on IB but nothing showing on eSignal. Any reason why? Those options are good because I called the exchange to make sure they were valid.
I re-booted eSignal a few times throughout these sessions and still didn't change anything. I need a good, reliable data provider. Any ideas for the discrepancies?
