I did my arbitrage long NG short UNG

|Includes: NG, The United States Natural Gas ETF, LP (UNG)

I shorted UNG at 11.54 and made a long at 3.279 in NG october.

I did prudentially 50% of arbitrage I'm willing to do, so if it take more premium I will add some position, if will reduce I won't take a profit quickly and I will wait more.

I think I did the arbitrage around 14,5% premium. So I will close not before of a 11/10% premium.
