As indicated in the graph above, the CNY premium to USD implied by OKCoin price relative to BitFinex, is now flat, after reaching highs of 15%.
In the futures markets, OKCoin weeklies are at a discount to the Index, and quarterlies have only a $2 premium. This backwardization in the market is reflecting not just excessive sell pressure by traders, but also a hanging margin call at $340 of 18,000 contracts, which will run a socialised loss because the insurance fund was depleted in the settlement today.
