I have some real nice short setups in the energy sector ETF's that should provide good setups into next week. FCG @ 4.39 has close to 90cents under it, IMO. 30 cents is a good ATR stop, plus would put you right at the previous swing high. Might give it a few cents to flex, but I don't think it gets anywhere close to the stop, and if it goes hard upward on Monday, I would just have to say I was wrong long before 30 cents up at the 4.7 area.
You could play it the GASX (3X bear FCG) and the volume is better lately, but still real bad with a lot of bid/ask spread. Last few days have moved 400K+/day, so it might work out. GASL (3X bull ) would be great if you could get the shares to short. I have never tried it. Also you might short XOP or use the (3X short DRIP). All these would work, but I am charting FCG and select equities.
Good Luck.
