i was an options ETO trader for a while, and there were these stories floating around about this old dude, an ex Qantas pilot who was "Mr BHP" and could work out any option price in his head on the spot with dudes yelling and pointing!

Always remember that and shake my head with the exams you had to pass to trade, they were tough!

Cheers
