here are the so called negative values in CNY:
OKCoin:   4,825 CNY =    714.28 USD
BTCC:    4,815 CNY =    712.81 USD
Huobi   4,821 CNY =    713.73 USD

and by the way these three exchanges have 2,549,523,000 USD combined volume in the last 24 hours alone with their prices even higher than USD markets.
