This sounds very plausible, but: I don't remember any cases when I've ever heard of specific platform stopping trade for specific stock just for volatility. I've heard about the cases of trade stopping when something clearly going wrong - like market crash, or bot-driven feedback loop, or such. And this usually then comes for the whole exchange or all exchanges the stock is listed on, not just a handful of platforms. That of course doesn't mean it didn't happen - just that I haven't heard of it. So is such thing common and does anybody have examples of such things happening in the past - I understand it may not gather as much press as this one but somebody should have mentioned it somewhere? Is it indeed a routine thing that got overhyped, or is it an exceptional thing trying to hide behind a routine procedure?
