I continuously got screwed the last week and today on options order execution. I cancelled orders, got order cancellation confirmation and then when the options went from 20cts to $1.20 I all of a sudden didn't hold them anymore...executed in retrospect. Then today an order disappeared that I had in. Couldn't find it anywhere and then all of a sudden it appeared again. For around 45sec I could not change that order. On Friday, I lost out on 7k profit because of their system and lack of appropriate order execution.
