Consider that your expensive lesson about the dangers of short-selling even when you're absolutely sure the price will go down.

Leverage and position sizing, not short selling. People with the exact opposite trade also got blown out today.

well you don't know how much he lost. It could have been say $1000. Evidentally, the contract was designed to trigger a closure of the position when it dropped out. At a 50x short, an "investment" of $1000 would have yielded $10k on today's turn of events.
