Announcement
To provide a more seamless trading experience and allow for earlier contract rollovers, we are pleased to announce an enhancement to our Futures Contract Transition Logic starting March 2026.
What is Changing: We are introducing an earlier opening date for new contracts and a concurrent “Close Only” period for expiring contracts. This allows clients to transition to the next contract month with greater flexibility before the final expiry.
New Transition Logic:
| Product Category | New Trading Session From | “Close Only” for Expiring Contract | Expiry Time |
| Index Futures | 2 Days prior to expiry | Set when new contract opens | At contract expiry |
| Energy Futures | 7 Days prior to expiry | Set when new contract opens | At contract expiry |
Close Only Phase: Once the new contract is launched, the expiring/old contract will be set to “Close Only” at the same time. No new positions can be opened on the old contract
Below is an illustration of how this new logic applies to upcoming contract cycles:
| Trading Product Name / Instrument | Expiring Symbol | New Symbol | New Trading Session Starts | Close Only Time (Expiring Symbol) | Expiry Time |
| US30 (futures) | US30_H6 | US30_M6 | 16/03/2026, 23:01 | 16/03/2026, 21:55 | 18/03/2026, 21:55 |
| WTI Oil (futures) | USOIL_J6 | USOIL_K6 | 06/03/2026, 23:01 | 06/03/2026, 21:55 | 13/03/2026, 21:55 |
Clients are encouraged to monitor their positions and utilize the earlier opening of new contracts to manage their exposure effectively. Should you have any questions regarding these changes, please contact our support team.
Best Regards,
ZFX Team
