Bitcoin and Ethereum indices on Nasdaq’s GDS go into effect today


Effective Monday, February 25, 2019, Nasdaq, through its data dissemination relationship with Brave New Coin, will send real-time Bitcoin and Ethereum index level information on the Nasdaq Global Index Data ServiceSM (GIDS), the stock exchange confirmed today.

What are the new BTC and ETH indexes?

The Bitcoin Liquid Index (BLX) and the Ethereum Liquid Index (ELX) are each designed to provide a real-time spot or reference rate for the price of 1 BTC and 1 ETH respectively, quoted in USD, and based on the most liquid ends of their markets. Both indices are calculated using a methodology that has been independently audited against key IOSCO principles. The BLX is one of the most widely-referenced BTC indices among crypto traders and has been calculated back to 2010. Likewise, the ELX has been calculated back to 2014.

According to the official announcement from NASDAQ, data recipients will receive real-time BLX and ELX index information from the proprietary GIDS data feed every 30 sec.

In addition to the real-time tick messages, Nasdaq will also support Equities Summary, which will be disseminated at the end of the U.S. and European trading session to relay the summary of the current trading day’s activity for an equity index. Stock exchange will also provide data about Index Directory, which will be disseminated at the start of each day to relay basic index information.
