Dear Member,

To prepare for the Summer Daylight Saving Time Change (DST 23, Short Clock Change), which will take place overnight between Saturday 29th of March 2025 to Sunday 30th of March 2025, a test session relative to the DST23 will be scheduled in the ETS simulation 2 environment on 13th March 2025 and 19th March 2025 for trading day 29th March 2025. For the full communication, please see link here.

This test is optional, but participation is strongly advised, especially for members using an API access. Members using the ETS client are advised to participate and familiarize themselves with the DST order submission and market result format.

There is no registration needed to participate in the DST test. Members will simply need to connect to the simulation environment and place bids for trading day 29th March 2025 (Delivery date 30th March 2025). 

Please note: Unexpected ETS client behaviour has been observed on this day. ETS client will become unresponsive when members click on the “Show Indexes” button. Therefore, please be reminded to not use this feature for trading day 29th March 2025 (Delivery date 30th March 2025). Instead, please use the Market results option. All the other buttons are unimpacted. The API is not impacted.

There are no changes to the sample files. Please find the sample files from the DST23 2024 test still applicable for DST23 2025 here.

Please do not hesitate to contact us at info@semopx.com should you have any queries.

Kind regards,
