Using "All or none" is perfectly legitimate for a LOT of reasons. Some people do it because the math is easier on blocks with even numbers of shares....to each his own.

But...if you place a 7m AON sell order for a stock that has daily volume of 1.5m - 3m shares, you're essentially saying "I don't want to sell these, I'm just here to be a nuisance."

...or it could be someone that doesn't know any better. As often as it appears, I doubt that's the case.
