SeDeX extended trading hours (ETH)
With the migration to the Optiq® platform, starting from October 2, 2023, the SeDeX market opens up to Extended Trading Hours (ETH). Issuers will have the option to choose for each individual instrument:
- Two different morning opening times (08:00 or 09:05)
- Three different evening closing times (17:30, 20:30, or 22:00)
Information regarding the combination of opening and closing times chosen by the LP for each individual instrument is available through the Trading Group. The Trading Group identifies a group of securities characterized by common factors, especially the trading market, the issuer (only for the main ones), trading hours, the RFE parameter, and the settlement system. Borsa Italiana provides details of the Trading Group for all SeDeX and Cert-X instruments through various sources:
- Standing Data Optiq (file OptiqMDG_Production_CashStandingDataFile_WarrantsAndCertificates_YYYYMMDD) and (for customers who have subscribed to the service) extended Standing Data (file BRED_REFDATA_PLUS_SEDEX_YYYYMMDD)
- Notice of the start of trading (for new listings)
- Borsa Italiana's website, within the product sheet for each individual instrument
