volatility before crash

I am amazed at the wild swings in the dow...

I now fear that a crash is iminent. Maybe thats what we need to find the bottom. Instead of a slow decline we need a 20% drop in one session and hopefully it can find a bottom then...

Such volatility is always followed by a crash. Question is when will it happen? I know people may not like it but I think it is needed so that we can have some sort of a bottoming out.
