Cboe Silexx, a multi-asset order execution management system (OEMS) that caters to the professional marketplace, has announced the release of version 26.3.
Closing Price | Current Day Closing Price Display
Equities now display the current day’s official closing price in a new Close column across multiple modules including:
- Order Ticket’s Quote Panel
- Portfolio
- Watchlist
- Risk Radar Position Columns
- Option Chain Underlying Columns

The closing price appears when available and remains visible through extended trading hours and overnight. This allows users to distinguish between the official close price and after-hours or pre-market activity. During the core session, this value will match the value in the Previous Trade Close column.
GTH | Support Trading of RUT and RUTW
Silexx will support the trading of RUT and RUTW options during Global Trading Hours (GTH) which run from 8:15 p.m. ET to 9:25 a.m. ET.
Portfolio | Enhanced Symbol Column Sorting
A new custom sorting logic has been introduced for the Symbol column in Portfolio, ensuring option contracts are now sorted by underlying, expiry, strike, and call/put type. This improvement resolves previous issues where strikes were listed out of numerical order and provides a more intuitive view by grouping related options with their underlying symbols. Existing groupings have also been updated to support this enhanced sorting method.
