EEX Natural Gas Index – Next Day Index: NDI

The EEX NDI is the volume-weighted average price of trades in the day contracts with delivery on the following day executed between 8:00 and 18:00 on the calendar day before the start of the delivery day.

The NDI is calculated and published on every calendar day, including the weekend, making sure you always have the most recent price reference for next-day delivery. From Tuesday to Friday, the NDI is equal to EGSI. On Friday evening, the NDI is calculated for the delivery day of Saturday based on trades in the Saturday day contract. Likewise, on Sunday evenings, the NDI for the delivery day Monday is calculated based on trades in the Monday day contract.
