I don't think that is the reason. I use AON orders all the time and I have never seen that happen while my order is sitting out there. This could be a result of a crossed market or it could simply be the market makers are playing games by trying to lure in buyers with the hope of trying to get out at the higher bid price.
Yeah, I saw that too. It's probably some shorts covering. Be careful D if you plan on averaging down. This is trading exactly like yesterday. The sellers came storming in right around this time yesterday.
