That really weird trading pattern has occurred again today - anyone got any idea as to what is going on? Exactly the same pattern of a sequence of small to large trades, all CXXT, all mid-price, is happening every few minutes, and all in the same second each time. (There are a few other trades in with them). I find it really really difficult to believe that these are above-board trades, but it's still hard to see what their ulterior motive could possibly be.
