Just for information, I just did one sell and one buy (the next day).

The sell was a limit near the top of the spread. It sat all day but filled at 6 minutes before the close. The underlying stock barely moved. Less than 0.10%

My initial buy limit was 1/2 way in the spread. It did not fill.
I changed the limit closer to the ask, and it filled immediately.

FWIW, the spread was 11.9% -- 201 bid, 225 ask.
Initial was 213.15, then changed to 213.25 which filled.
