Well, I was buying a 2 bn company today. Bid was 29.2 and ask was 29.24. I put in an adaptive limit order at 29.24 but only got 200 shares filled, and price immediately jumped up to 29.28/29.36. I had a similar experience with another stock where the moment I put the order in, the price jumped. I won't think it is coincidence because I was staring at the screen for minutes when I was doing the last round of sanity checks and price was not moving, but the moment I click the confirm button, the bid/ask changes. That's just too unreal to be coincidence.
Sounds like volume is pretty low for that company and you got stuck in the market maker shuffle.
