After hours options fills


I have send a trouble ticket a few times after C2 filled options after regular trading hours. Why does C2 show these after hours fills? I don’t think option fills past 4pm EST are realistic or even possible and I think therefore they should not occur.

ST: Options are printing pre/post market on large caps. The OCC started trading pre and post market a week ago.

Thanks Stone Hedge…

I wasn’t aware of the pre-market trading that began a week or so ago…

good to know.
