It's really interesting to see the power of the Gap, no matter down or up.
And once the Gap was closed above or below daily, then the resist/support function switches.
Based on the theory, we can long or short once you had a clear closed-signal about the gap.
Meanwhile we have to see some gaps in history by draw a ray from them.
So this week USOIL closed above Gap on Nov 30th,2015.
In my opinion, there is a great probabilty that USOIL will retest 41.83 or 39.62.
Both positions are good entrys for long.
Trade safe. No news is good news.
