Closing nat gas position

Bought to close $BOIL 12/18 60/70 bear call spread @ .10. Sold for 1.30 on 8/5. Nice profit but almost 4 months to get there even as the underlying was mostly trending down since August. Low liquidity played a big part as well, not allowing me to get out for a decent price. Finally able to take it off today. Barring any crazy moves in nat gas, I will probably avoid this one going forward.
