large volumes (liquid), very deep order books (lots of orders to play off each other, and also calculate optimium supply/demand points)

Agree, high volume.

(1) Why is Etrade on the list? Sticks out like a sore thumb.

(2) They are claiming volatility is higher? I thought HFT firms were saying they made markets less volatile? Or is it indexes less volatile, but individual stocks more volatile?
