Norwegian oil fields are nationalized. The major source of revenue is not from taxes but from direct profits in oil production. Equinor (former Statoil) is majority owned by the Norwegian state and has a revenue of $62B.

Thanks Bob,
Can you share with us how locals typically traded options on the floor. Was it just a matter of being on the bids and offers and trying to be ahead of commercial flow?
That was filmed right after he lost millions. So the hesitation is probably more like a reflection on what the f*ck he is doing. I don't think he cares much what a cab driver thinks about him.
1. Take UL = UL - delta/gamma
2. Calculate new delta and gamma by plugin UL in BS calculator.
3. If |delta| > epsilon, where epsilon is a small positive number, goto 1. Else UL is UL(delta=0).
