Uhm. So, some people bought the whole 2400 CNY wall and minutes later the price is 2397 CNY. Hmm...
I thought price will shoot sharply either up or down after that wall disappears. But nothing happened yet. Strange.

Yup... somebody bought from themselves in an effort to trick the market. It happens from time to time. Points like that are particularly dangerous because people change directions a time or two on a trade. I, personally, need to learn to sit out at points like that. At least I'm starting to recognize what that pattern looks like. Progress!
