Highly doubt that an order was entered high and filled at that price. For years I've been doing it this way. 1) Make a decision to buy or sell. 2) Enter my bid at way over ask or way under bid. It has always, without one loss, filled at the MM bid/ask, just like the rest. Yet too many daytraders chase the bid/ask and miss, having to buy at a higher price or sell at a lower price, while I just filled.
It's more likely that it was 1 of 2 things to get those shares at 1.45. A cover that could only be accomplished at that price, or MM's picking up shares (tens of thousands came through) with someone's GTC sell order.
