On the stock I was trading, the bid suddenly jumped by about $.30 (to $20.04) with a bid size of 300 shares on NYSE. I quickly placed an order to sell with the smart route 300 shares, and the order wouldn't go through. I noticed it was routed to Island mysteriously--as the bid was on NYSE, and plus it almost always goes to NYSE. About 7 seconds later, the bid was taken out by another party, and the bid dropped by about $.30. Only then would my order be switched from Island to NYSE. A) Can someone please explain to me what happened? B) Is this the breaks of the game?
