I did that in fact, sold a couple at $2 (They traded up to $5.7 intraday yesterday, but of course I didn't manage to catch any at those prices). Before Market open I was putting sell orders for those at $3.5 and $5, IB cancelled those orders before market open (With a message saying that price is too far outside NBBO!!!) Besides, at IB, GME options opened late as well, not at 9:30 as it was supposed to.
Honestly, I don't know. This is the first time I saw this message from IB. My orders were sent and accepted (green status) before market open by around 20 mins. IB cancelled the orders right after market open and I got this message. I placed tons of orders in other instruments before which were way too far from NBBO and there was no problem (The like of bidding 1000 shares @$0.5 for a stock trading at $10), didn't face this problem.
Probably not, judging by the other IB order “protection” measures. I ran into this too, but re-placed the orders and got a few fills on GME options yesterday.
