OCC's Future Clearing Platform

Recent Updates to Content and Documentation

December 23, 2025: In June, OCC temporarily paused external testing activities to focus on high-priority internal Ovation initiatives that, once completed, will give us the insights and data needed to ensure we will provide an optimal experience for market participants when Ovation testing resumes.

Based on our progress so far, we anticipate reopening Ovation testing with market participants in Q2 2026. Review the recent Information Memo for more details, and learn what functionality will be available when Ovation testing resumes in the Ovation External Testing Functionality document.
