wow, i had prepared for some bear power, but this was unexpected. okcoin quarterly futures just dropped to $4755! that's 31% lower than all the spot exchanges (even more at the extremes)....wtf happened?

i can't tell if a huge contract holder getting liquidated caused a cascade, or if something went very wrong with their order matching system. either way, the okex chart is completely rekt. what a shitty day....
