OSH Chart, page-23

@Teddyward most CFD providers will let you short OSH and offer a decent level of margin.

Two other ways you can do it, but a put option or purchase a mini short warrant on market;
OSHKCQ, OSHKOQ, OSHKOS or OSHKOT depending on how tight you want your stops / level of gearing.

I however am punting on the long side in the short term, $6.71 first stop, $6.80 and then potentially a retest of the 200 day moving average at $7.00

Plenty of artciles out over night for and against a move higher in the oil price in the near term;
