I watch ugaz and dgaz pretty closely and typically see $1 spreads on Thursday's inventory report. Not uncommon to see $.30 or even $.40 spreads. Not enough volume on these dogs to have tighter spreads. I trade nugt, which has a lot of volume, and never see spreads more than $.02.
The poster below is correct. Don't use stops on dgaz or ugaz. I think the market makers will take you out given the opportunity. I have been stopped out a few times to the penny to watch an immediate bounce.
