Cboe Silexx is removing nightly restarts — the system will now run 24 hours a day, 6 days a week for uninterrupted access during trading hours. The new maintenance time is Saturday around midnight EST.

Expired orders will be removed from the order manager at 8:00 p.m. EST and will be accessible via order history.

• API | gRPC Reflection

gRPC API users can now access the most up-to-date proto files by using server reflection.

• Risk Radar | Save Step Percent

The percent change between price slices will now persist across sessions, if the workspace is saved.

• Option Chain | Remove Expiration and Underlying from Strike Column

The center strike column in the option chain can now be configured to exclude the expiration and underlying. This setting is in the option chain settings menu.

• Chart | Added Additional Time Frames

2, 4, and 10 minute charts are now available.

• OC | Enhanced UI for Ex-Dividend Dates and Earnings

The highlighting style has been adjusted to make upcoming ex-dividend and earnings dates more noticeable within the option chain.
