RE:RE:FUDWell Snowballer, with all due respect, I don't understand your attention on wti. Bte sp has much more of a correlation with wcs. You can see it in the charts. When bte was around $8, wcs was over $70. When bte dropped to below $4, ws was around $56. The macro maps quite well onto the micro. Anyway just as an exercise I'll learn more about moving averages and see if I can come up with some sort of function relating bte sp and wcs moving averages. You can find all info here: https://oilprice.com/oil-price-charts/
