I'm having a hard time understanding something...
as of today for Natural Gas...
Year Δ M2-M1 Δ M3-M1 Δ M6-M1 Slope M3 Slope M6 Slope Y1 Slope Y2
2020 4.50 3.68 -3.50 2.92 -1.93 0.04 -0.67
Isn't M2 just the next month futures contract and M1 is the current Month (i.e... Feb-Jan)...I thought the 2020 number under that column would be the calendar spread of Feb-Jan, but it's not making sense...
