As I placed my bid, three lots were pulled from the next Ask position just seconds afterwards. It was an obvious attempt not to lose them to me should I decided to chase and served as a block from larger sized Asks. I think it is evidence of what you both said. Alone it means next to nothing but I have seen it so many times and yesterday spent most of the morning playing cat and mouse with those small lot offers.
Anyways I get a thrill when I manage to swipe a few of those offers.
Cheers.
