Has anyone else noticed that the volume and volatility spikes at 8:30 EST are getting bigger and bigger? This weird behavior extends beyond the ES to the YM, NQ, and the premarket trading of Spyders, Diamonds, etc. I always thought these premarket spikes were some form of program trading related to European markets, but now I am begining to wonder what is up? The number of contracts pushed through in just 2 or 3 minutes has lately exceeded the normal volume of 2 or 3 minutes during market hours. Weird. Anyone know anything?
