I had a buy limit order @ 13.60 in TASR 110 May puts. Order was filled. I sold @ 15.90. Now about 2 hours later ISE is telling me that my buy order is busted. Of course, puts are much higher now. They are @ 21.00 now. IMHO ISE is not acting fair. This isn't a fair game. IMHO a local was triggering my order and then he told the exchange to bust it after it went in his favor. During the time of the filling of my order the current bid with smart order tool from IB was about 14.40. Why didn't a seller hit this order? IMHO some local steals my money and ISE is accepting that. Has anyone experience with such a thing? What can I do? I don't want this criminal to walk away with my hard earned bucks.
