Notice Regarding Bitcoin/USD Products (Index, Tick Size)

Bitcoin / USD 30 June 2017 Futures Contract

The BitMEX Bitcoin / USD 30 June 2017 Futures Contract (XBTM17) listed today, 17 March 2017 at 12:00 UTC. This contract is similar to XBTH17, but uses a new index, described below.

.BXBT: The New BitMEX Bitcoin / USD Index

.BXBT is an equally weighted index using the Bitcoin / USD spot price from the following exchanges:

  • Bitfinex
  • Bitstamp
  • GDAX
  • OKCoin International

XBTM17 uses the .BXBT index. Any exchange that is down or displays stale pricing data for 15 minutes or more will be removed temporarily from the index. Once the price feed is operational at least 5 minutes, we will reinstate the exchange.

A page detailing each constituents’ individual price and history will be live soon.

The BitMEX Bitcoin / USD 31 March 2017 Futures Contract, XBTH17, will continue to use the existing Bitcoin / USD Index (Symbol: .XBT; Weights: 50% Bitstamp, 50% OKCoin International) until it expires.

The BitMEX Bitcoin / USD Swap, XBTUSD, will continue to use the existing Bitcoin / USD Index (.XBT) until 31 March 2017 12:00 UTC. It will then switch to the new index. This is the same moment that XBTH17 expires.

Increase to Bitcoin / USD Products’ Tick Size

Also effective 31 March 2017 12:00 UTC, the tick size for Bitcoin/USD products (XBTUSD, XBTM17) will change from 0.01 USD to 0.1 USD.

Important Changes to Bitcoin / USD Swap Funding
3/8/2017, 2:01:40 AM

Occasionally the BitMEX Bitcoin / USD Swap, XBTUSD, trades at a significant premium or discount to the mark price. This generally happens during periods of extreme volatility.

In order to ensure that the XBTUSD product trades close to the mark price the following change will be made.

Given 8 hours’ notice, BitMEX may decrease the funding interval from 8 hours to 2 hours to allow funding rates to better reflect the market. The leverage will remain unchanged at 100x. The funding interval will subsequently be increased from 2 to 8 hours after the market has stabilised.

An 8 hour funding interval means that the maximum amount of funding paid or received is +/- 1.125% per day. A 2 hour funding interval means that the maximum amount of funding paid or received is +/- 4.50% per day.

Notice Regarding COIN Prediction Futures
3/6/2017, 2:43:47 AM

The SEC decision regarding the Bats exchange rule change is due by 11 March 2017. This decision, if positive, will allow the COIN ETF to list. Because this is a Saturday, there is a possibility that no public announcement will be made until Monday 13 March 2017.

The COIN Prediction Futures contract, COIN_BH17, will now settle on Tuesday 14 March 2017 at 00:00 UTC. If a public announcement regarding the rule change is made by the SEC prior to the settlement date, BitMEX will settle the contract early pursuant to the payout guidelines.

Frontend Update: Feb 13, 2017

We have a minor update this week:

  • We’ve standardized and reworked some of the margins across the site. You may notice that panels look very slightly different now. You may have to resize your custom layout as a result.
  • The orderbook panel is now expandable! You can view as many (or as few) rows as you like:
  • We’ve made more performance improvements to the site. Please let us know if you still are seeing slow tabs or high latency on internal actions; if you know how to use the Chrome debugger, a zipped timeline sent to support@bitmex.com will help us diagnose any individual performance issues.
  • We fixed a bug where amending an order of one instrument while another instrument was active would generate an incorrect warning.
