Current Status of SIDC Corrective Measures Preparation
OKTE, a.s. would like to inform Market Participants about the status of preparation of Corrective Measures (CMs) within the Single Intraday Coupling (SIDC).
Corrective Measures are temporary instruments designed to stabilize market operations in case of deteriorated algorithm or intraday trading system performance. Their purpose is to ensure stable and reliable SIDC operations, and their use is limited to operational situations where saturated trading activity could lead to system performance challenges.
According to the latest information, NEMOs and TSOs continue preparations for several corrective measures.
The reduction of Orderbook Depth from 100 to 50 did not provide conclusive performance improvements and, therefore, the Orderbook Depth will be restored to 100 in June 2026.
At the same time, preparations continue for the temporary adjustment of the Price Tick Size from 0,01 EUR/MWh to 0,1 EUR/MWh, which will be available for Market Participants’ testing between 22 June 2026 and 28 August 2026.
In the area of order management, additional measures are also being analyzed, including the Order-to-Trade Ratio (OTR) at NEMO level and the number of orders per defined timeframe at Market Participant level.
The full Status of Corrective Measures document is available in this link.
Information about all corrective measures can be found on our website in the "Corrective Measures" section.
