China's Shanghai Index is trading down over 6% about half way through its trading day. It is mostly in part to transaction fees tripling in their trading markets.

Remember, on Feb 27, Chinese markets sold off 9% and the down dropped 500 points. You'd have to think that we'll see some response tomorrow in our markets.
