Thanks for comment. I was trading out of AMZN options at the time and caught it. It made my jaw drop. I hadn't seen that live like that since Aug 2015, but then it was more wide-spread (I lost of a lot of stock on whatever day that was, the 25th or so, because I had my stop losses programmed into IB. I didn't know better.
If you have people in your feed/circle who trade, feel free to resteem. They might find it useful.
Have a good one!
