Summary

Joyride runs on a 24/7 schedule.
  • Trading rounds are 24 hours
  • Settlement happens at 08:00 UTC
  • All timing in this guide is UTC
Joyride currently lists same-day (0DTE) instruments. At each daily rollover, the expiring round is settled and the next round is bootstrapped.

​
Daily schedule

​
Round duration

Each trading round lasts 24 hours. The public market config endpoint exposes the same policy in machine-readable form:
  • GET /v1/market/config
Key fields:
  • round_duration_hours
  • round_epoch

​
Settlement time

Options settle at 08:00 UTC on the expiration date encoded in the instrument ID. Example:
  • SOL_USDC-12MAR26-150-C settles at 08:00 UTC on March 12, 2026

​
TWAP window

The settlement TWAP window begins 30 minutes before settlement. For the standard 24-hour round:
  • TWAP window start: 07:30 UTC
  • Settlement: 08:00 UTC
The oracle settlement endpoint exposes the live countdown:
  • GET /v1/oracle/settlement
Key fields:
  • next_settlement
  • twap_window_start
  • seconds_to_twap_window
  • seconds_to_settlement
  • in_twap_window

​
What happens at rollover

When a round expires:
  • expired instruments stop trading
  • open orders on expired instruments are cancelled
  • positions in the expired round are settled
  • next-round instruments are created and broadcast
For client behavior, assume rollover can change the available instrument list immediately around settlement.

​
What traders and agents should expect

​
Before settlement

  • instruments for the current round remain tradable until expiry
  • agents should prefer live instrument discovery over cached IDs
  • settlement countdown data comes from GET /v1/oracle/settlement

​
At settlement

  • requests against expired instruments can fail with 1009 (Market closed or instrument expired)
  • authenticated sessions can receive settlement updates on the settlement channel
  • authenticated clients can receive a settlement_complete event when the round finishes

​
After settlement

  • the previous round is no longer tradable
  • the next round’s instruments are available after bootstrap
  • clients should refresh instrument lists instead of assuming the previous set is still valid
  • Treat instrument IDs as short-lived for 0DTE workflows.
  • Query live instruments at the start of each session.
  • Refresh instruments again if you are near 08:00 UTC.
  • Use UTC consistently in logs, prompts, and dashboards.
For most agents, the safe pattern is:
  1. list_instruments
  2. pick a current instrument ID
  3. trade or quote it
  4. re-check instruments if settlement is approaching
