So I've got some shares of AMC still. I saw it pop in after hours and wanted to finally get out while it's trading at nearly 4x what I bought it for.
I originally put in a limit sell order and the price went over my limit and stayed there...but I didn't get confirmation of a sale, even after 30 minutes.
So I cancelled the limit order and put in a market order to sell now at market price. Same thing, wait 30 minutes and no confirmation.
So I put in another limit order to sell at $11 with a full hour left in after hours trading. The price stayed above 11 and closed at 11.10, but I never got confirmation.

I'm using fidelity, and yes I'm signed up for after hours trading.

What on earth is going on here?
