I am a newer NY trader so I don't know how often this happens, but I can't see how it can be legal. So can I please get some comments on this from some NY traders. How often does this happen, is it legal, what can be done about it, or was it just a "fluke" trade and part of the territory? Today I was trading GE. I was short right in the morning and had a bid placed out there at 28.42 to get filled to cover the short. The specialist moved his quote to 28.39/28.41. He printed a ton of shares at 28.40 and some more at 28.39 which was the low of the day. However I did not get the fill. Before moving his quote down he was at 28.46/28.50. I had my bid out there maybe 30 seconds before he moved his quote down.
