DT moo : volatility has fallen?
元气少女洛丽塔 : Volatility. The volatility yesterday was at 200%. Today it directly returned to normal volatility. Options are no longer valuable. Volatility is a very important parameter in options pricing.
72941937 OP : I bought put options before yesterday's closing, why did the options open today and drop 90%, shouldn't it go up a little?
風升水起8888 : Mine is just as unfair.
元气少女洛丽塔 72941937 OP : Take a look at the volatility. Keep learning. Although I understood it yesterday, I couldn't resist buying the call. I have learned about the volatility double-kill options with another 500 US dollars.![[undefined]](https://static.moomoo.com/nnq/emoji/static/image/default/default-black.png?imageMogr2/thumbnail/36x36 "undefined")
