Shorting GDX

I would like to short GDX, but my broker has no shares available. Is there another ETF that is similar to GDX that could be subsituted? I can short GLD but it does not move near as much as GDX.

 

Puts have plenty of liquidity, 5-10 cent spreads and lots of volume thru June.

 

Yep and the short gold ETF 3x is one also

 

Are we looking at a slight run up near term ?? with euro ??
I 'm thinking it could happen.

 

buy and sell same strike put and call
