Aren't you basing an investment decision on historical evidence alone? I see no future in history.
The fight to reduce impact of RINs took an interesting turn this week, thanks to force being applied by Icahn. A push to acquire Delek is hurting, either.
There are "drivers" afoot, moving decisively to exert greater influence. I think it would be foolhardy to revert to TA at such a volatile time.
Good luck to you, regardless of my thoughts.
