You all realise that the whole China waking up thing doesn't hold water. A huge range of people trade on the Chinese exchanges. Apparently most of their clients are in Denmark.
Based on the pattern of volume on the 1h charts, I could believe that 30% of OKCoin's clients are outside China, at most. On Huobi they may be 20%.
However, an unknown percentage of those "foreign traders" must be automatic robots, doing high-frequency trading or arbitrage 24/7, in China or outside it.
