Of course you don't really know if its a successful retest until after they have rallied away from their lows but some MLPS this week have come down to their August lows and are moving a way from those lows right now. Penn Virginia Holdings (PVG) is one of these as is DCP Midstream (DPM) is another. I am long both of these btw and have bought some more PVG. They never make it easy.
