Neat trick - when things get tough, just halt trading!
Shanghai's chart looks like a classic bubble chart: 250% gain in less than a year, and now crashing.
Volatility in US markets is definitely on the rise. I'm daytrading VXX and XIV. For anyone who does not know, VXX should not be held more than a couple of weeks - it is structured to go down over time. XIV is different - it can be held for longer periods. If we get a strong sell off, I plan to buy XIV when I think the bottom is in, and hold it for a month or so.
