After review of the feedback and suggestions received from our customers, OKCoin will be making the following changes to the futures platform with regards to contract maturities and price index composition.
On December 12th, 2014 at 4pm Beijing time, the existing monthly contracts - BTC1226 and LTC1226 - will become the biweekly expiry. OKCoin’s futures platform will thereafter no longer be listing monthly expiry contracts. The tenors on futures will be weekly, biweekly, and quarterly only. This is consistent with what was first announced on November 21, 2014.
On December 12th, 2014 at 4pm Beijing time, after settlement and payoff calculations are complete, OKCoin will be making an adjustment to the composition of the BTC price index. BTC-e will be removed from the index. The remaining constituents shall be OKCoin.cn, Huobi, BTCChina, , Bitstamp, and itBit. The index will take in prices from these six exchanges on an equal weighting basis.
