Don't believe everything you see on L-II....just because the bid or ask looks thin doesn't mean it is. The market game is a war, and the art of war (as most know) is deception.
That's why when the "smart money" is either buying or selling.....they're not doing it with their laptop sipping a double double at Tim Hortons.....They hire a Market Maker Broker Dealer.....and MM for short. Rather helpful seeing as MMs set the bid ask and can easily short.
