I think it's basically just replacing having a circuit-breaker -- if they had a circuit breaker like a lot of other exchanges, the crazy price jump never would have gotten going.
Saying short positions should not exist is equivalent to saying commodities producers should not be able to hedge production risk.
That has wild implications for commodity prices and availability around the world. If that’s your position you should probably state it more directly.
This is because of the natural limits of hedging short positions.
Circuit breakers aren’t designed to protect traders from betting too much, they are designed to prevent the market itself from breaking in unforeseen ways.
