RE:RE:Crack spread at new all time highThere are multiple crack spread.
I use the 3-2-1 methode
The 3:2:1 crack spread is calculated by subtracting the price of 3 barrels of oil from the price of 2 barrels of gasoline and 1 barrel of distillate.
I have been calculating this on a regular bases since 2007.
You can Google "crack spread calculation2 and will find multiple exemples.
Hope that help.
