On the Line price chart I see the last trade price was 18,26 with the volumes of 200. At the same time the best bid price is 18 and the best ask price is 18,29. I have placed an odd lot to sell 47 shares at 18,26, but it was not filled. How is possible that there were other trades with the price 42,26 but there were no bid? Cause if there a trade it means that somebody bought and somebody sold the share.
It was on the NYSE Exchange.
