A $5 move against you in the CL (very possible given recent volatility) would mean a loss of $5000, disastrous in small accounts. What about selling a call, long the future, so the option delta reduces overall exposure to movement of the underlying; thus reducing overall leverage? Meanwhile you gain some time decay, too. Best to sell an ATM, ITM or OTM call?
and how do you protect 5 (or 15!) point move on the downside? CC is a limited hedge with a cap on the upside. Also check collar: http://www.meta-formula.com/future-options2.html
