Quote from Euler:
Thanks for the link.
The ban did seem to affect markets, in one way that's not discussed in that article: bid/ask spreads skyrocketed, making these securities much more expensive for liquidity takers to trade. Unable to hedge or offer to sell without stock, many participants simply refused to make markets in these securities at that point. The result: not only did these stocks continue to plunge, but it seems that they also plunged much more chaotically than they would have otherwise.

market makers refuse to bid if shorts keep hitting the bid on downtrend or hitting the bid on weakness.
