BitMEX Indices

BitMEX indices are composite, meaning that they are calculated using a number of data sources. BitMEX currently has 18 data sources: Binance, Bitfinex, Binance US, Bitstamp, Bittrex, Bybit, Cryptodotcom, Coinbase, FTX, Gateio, Gemini, Huobi, Itbit, Kraken, Kucoin, LBank, OKEx, Poloniex.

Aiming to be representative of the underlying asset’s market consensus price, each BitMEX index is calculated as a weighted average of the Last Price for each constituent exchange. Index prices are calculated and published every 5 seconds. The index weights are shown in the table below. The constituents and index weights are reviewed and updated on a quarterly basis. Changes will be announced on the BitMEX website, on the BitMEX blog and via the BitMEX RSS feed, with three weeks notice before implementation. The BitMEX “NEXT” indices will be published at that time to track the hypothetical price of the indices with the new weights.

BitMEX Index Weights, assuming no constituent exchanges have been excluded due to Index Protection Rules, applicable from 24 June 2022 at 12:00:05 UTC. For current weights incorporating any exclusions refer to the relevant Composite Index Breakdown.

The BitMEX index weights will be updated next on 30 September 2022 at 12:00:05 UTC.

Update Schedule

The weights for BitMEX indices will be updated immediately after each quarterly futures expiry, with updates based on three months of constituent exchange volume data. The date range for data will be from 00:00 UTC on the first day of the month for the expiring quarterly future to 00:00 UTC on the first day of the month for the next quarterly future.

For example, at 12:00:05 UTC on 25 December 2020, updated weights will be used to calculate the BitMEX indices. These weights will be announced on 4 December 2020 and will be based on constituent exchange volume data from 00:00 UTC on 1 September 2020 to 00:00 UTC on 1 December 2020. These weights will apply to the BitMEX “NEXT” indices from 4 December 2020.

The BitMEX “NEXT” indices (eg. .BXBT_NEXT) will display the hypothetical index prices with the new weights. These index prices will line up with the normal index prices once the announced weights are live (ie .BXBT_NEXT and .BXBT will have the same price). “NEXT” indices are not used for valuation or settlement, they are used to display hypothetical index prices with new weights before implementation.

BitMEX “NEXT” Index Weights, assuming no constituent exchanges have been excluded due to Index Protection Rules, last updated on 3 June 2022. For current weights incorporating any exclusions refer to the relevant Composite Index Breakdown.

These “NEXT” index weights are computed using three months of constituent exchange volume data from 00:00 UTC on 1 March 2022 to 00:00 UTC on 1 June 2022.

The next update for BitMEX “NEXT” index weights will be on 2 September 2022.

Example Index Calculation for .BXBT_NEXT

On 2 February 2020 at 00:00 UTC the Last Prices on the constituent exchanges were:

Bitstamp Bittrex Coinbase Gemini Itbit Kraken
Last Price 9377.17 9384.336 9380.18 9380.6 9378 9377.1

These Last Prices are multiplied by the weights to give

Bitstamp Bittrex Coinbase Gemini Itbit Kraken
Last Price 9377.17 9384.336 9380.18 9380.6 9378 9377.1
Weight 10.61% 2.53% 52.30% 6.89% 4.21% 23.46%
Last Price x Weight 994.918 237.424 4905.834 646.323 394.814 2199.868

The sum of Last Price x Weight across all constituents was 9379.181. The sum of Weights across all constituents was 100%.

So the .BXBT_NEXT price was 9379.181 / (100%) = 9379.18 (rounded to nearest USD cent).

Index Calculation Methodology

BitMEX index is calculated as a weighted average of the Last Price for each constituent exchange. Index prices are calculated and published every 5 seconds. For indices with constituent(s) that require a Conversion Index, the Last Price for the constituent is calculated by taking the product or quotient of the Source Price and the Conversion Index Price, depending on the denominators of the index and the source.

Example index calculation with Conversion Index

The following .BADAT example is for illustration purpose only:

Binance (ADAUSDT) Huobi (ADAUSDT) Kraken (ADAUSD)
Source Price 0.170990 0.171003 0.170913
Conversion Index Not Required Not Required .BUSDT
Conversion Index Price Not Required Not Required 1.00072
Conversion Factor 1 1 1.00072
Last Price = Source Price / Conversion Factor 0.170990 0.171003 0.170790
Weight 72.26% 24.66% 3.08%

So the .BADAT price will be (0.170990 x 72.26%) + (0.171003 x 24.66%) + (0.170790 x 3.08%) = 0.170987.

Index Weight Methodology

The BitMEX index weights are computed using volume data obtained directly via API connection from each of the constituent exchanges listed above. Proprietary mechanisms are used to identify malformed and anomalous data, which is discarded. The index weight calculation removes constituents with insufficient trade volume. For the avoidance of doubt, and in accordance with BitMEX Terms of Service, HDR Global Trading Limited (operator of the BitMEX trading platform) accepts no responsibility for the accuracy of any volume (or other) data received from any exchange and used to calculate the value of any BitMEX index and excludes all liability for any claimed losses arising in connection with its calculation and publication of any such index.

For further information see the individual index and index weights pages, linked in the tables above.

Index Protection Rules

BitMEX uses several methods to maintain reliable connections to the constituent exchanges. As a fallback the following tests and actions are used:

1 If a constituent exchange is unresponsive, the previous price is used.

2 If a constituent exchange’s price is unchanged for 15 minutes, the constituent is removed from the index until it is operational.

3 (a) For indices with 3 or more constituents: if a constituent price differs from the median constituent price for that index by 10% or more, it is excluded from the index calculation.

3 (b) For indices with only 2 constituents: if a constituent price differs from the median constituent price for that index by 5% or more, the last calculated index price will be used. The index is updated once its price differs from the median by less than 5%.

3 (c) For an index with only 1 constituent: if the constituent price is 10% away from the last calculated index price, the last calculated index price will be used. The index is updated once the constituent price differs from the last calculated index price by less than 10%.

4 Excluded constituents are added back to their indices when one of the following conditions has been met for a continuous 15 minute period.

4 (a) For indices with 1 or more remaining active constituents, excluding the use of last calculated index price in 3 (c) above, the excluded constituent is within 2% of the median of the remaining active constituents’ prices;

4 (b) For indices with 1 remaining active constituent, using last calculated index price per 3 (c) above, or no remaining active constituents, the excluded constituent is within 10% of the index price.
