This is a bit funny, but sad, considering they're the biggest futures exchange in bitcoin. OKCoin has been pretty glitchy recently. Last week, its LTC/CNY orderbook glitched and went down to 0.03 CNY, they later blamed it on a "hidden bug" (?) in the trading engine. Alright I guess, par for the course in China...
And now their orderbook is showing negative contract values. Somehow there's an order for -7 contracts to sell, which I guess would mean buying 7, but the way OKCoin works is you only can Open Long or Open Short, so that means it had to be an opening of negative contracts. How this can even happen is unclear, but it may be an indication of backend problems, or just a websocket problem. It may just be a glitch rather than a bigger problem with their system. Either way, it's not very comforting to see your broker showing negative values in the orderbook.
