Theoretically, PRL hits oil SP skyrockets oppies are executed we will have further funds, PRL doesn't hit oil SP plummits and oppies aren't executed, no further funds and time for a CR.
All in all, recent reports released are indicating a higher probablity of hitting oil
Take your pick, your either in or your not. This end of the market is either make it or lose it.
