60 tic average true range and has been a dream to trade, very faithful to it's trend bias. RBOB Crack has been very consistent for clients since about February. HO Crack will lay low until October or so. ICE Gas/Oil Crack - legged 1:1 versus Brent using an automated spread execution platform, also trades and models very well for us. I have a client in Australia who has pretty much forgotten about the SFE 90 Day Bills to concentrate on this space during early European hours.
