Rangebound and false breakouts like this morning is nothing new. What is new is that three times this morning I saw a huge imbalance in the order book. Lowish hundreds ten deep on the bid, over 1000 lots per price ten deep on the offer, and vice versa. That isn't the usual spoofing around mid-market, it's either a new spoofer in much bigger size or something very odd going on. Ideas, anyone?
