Alternatives: could someone clarify Backwardation and normal backwardation?

I am kind of confused abt backwardation and normal backwardation…

What’s the difference?

Could someone clarify the difference? ’

Thanks!

Contango: CURRENT spot price < future price

backwardation: CURRENT spot price > future price

normal contango: EXPECTED spot price < future price

normal backwardation: EXPECTED spot price > future price

Interesting… thanks.

The thing I didn’t understand clearly is if normal contango or normal backwardation expected spot prices are the spot prices on the execution date of the future contract. It should be, right?
