I had 1-minute charts open for OKCoin, Finex and Stamp, and the latter two definitely followed. Not saying OKCoin necessarily led, but it definitely looked to me like BTC/CNY leading BTC/USD.
It's ridiculous to follow the Chinese exchanges with their tiny walls. Of course the NLC team is going to dump its two coins there and drop the price by ten dollars. How does it work, really?
