The European Energy Exchange (EEX) will introduce a new Trade-at-Index (TAI) functionality for its natural gas spot markets as of 15 September, designed to enable trading based on EEX’s stable and reliable reference values. In addition and to extend this reference pool, EEX is launching a new gas spot trading index under the name EEX530.
The EEX530 index is calculated as the midpoint between the best bid and offer prices at 17:30 CE(S)T from Monday to Friday. It is already available with data going back to 18 May 2026, while further historical data for the Dutch TTF natural gas market dating back to 2020 can be requested. The new index complements EEX’s existing and established indices offering for the gas market and is also available for licensing for use in contractual agreements.
The upcoming TAI functionality addresses the need for the fulfilment of diverse hedging requirements by bringing greater flexibility through enabling intraday trading at a price based on an index of choice. Market participants will be able to choose from the new EEX530, EEX End-of-Day Index or the EEX EGSI, all calculated at different times throughout the trading day.
The new functionality will cover Day and Weekend contracts for all European market areas available on the EEX gas spot market.
Peter Reitz, CEO of EEX, comments: “By introducing the new Trade-at-Index functionality, we are not only providing transparency and strengthening market confidence, but also addressing the strong demand from our trading participants for a tradable index on the gas spot market. TAI simplifies trading by combining physical delivery with index-based pricing. This provides trading participants with greater flexibility while reducing operational overheads at the end of the trading day.”
EEX strives to expand its product portfolio in line with the needs of market participants, including the recent introduction of tradable long-term maturities across the Dutch TTF, German THE, Austrian CEGH, and French PEG market areas.
EEX is the largest gas spot exchange in Europe and has seen strong growth in its gas markets over recent years.

By the end of May, the total volume of EEX gas trading in Europe amounted to 3,883 TWh, representing an increase of 10% compared to the same period of the previous year.
