Prices crossed but jupm still trading

  1. I was watching jupm this morning at the open. As the price went down, the bid exceeded the ask and stayed that way for maybe 5 minutes intermittently. But the stock was still trading down continuously.

    I've been paper trading for about a year now since I lost my edge, so naturally I'm confused. Have the rules changed or is there some kind of manipulation going on.

    How can I trade when the bid and ask are crossed.

    An explanation would be very much appreciated.
