BULK Mainnet Upgrade - Sunday, 18 October
We’re preparing the next BULK mainnet upgrade. Bringing improvements to matching, conditional orders, risk calculations and recovery, alongside the infrastructure for BIP-1 markets.
Maintenance schedule - UTC
- 12:00–13:00: Planned maintenance. Trading will pause, and API/WebSocket connections will be interrupted.
- 13:00–13:30: Controlled reopening. Markets will initially accept post-only orders and orders that reduce existing positions.
- 13:30: Target time for unrestricted trading to resume, following final validation.
We’ll share progress during maintenance and confirm when normal trading is available.
Order handling:
The planned startup cleanup will cancel ALO/post-only orders.
What’s changing:
- Matching and collateral budgeting: Improved handling of position reductions and available collateral during execution.
- Conditional-order processing: More consistent routing of generated actions through the normal execution and delay queues, with improved persistence across recovery.
- Risk, liquidation and ADL: Updates to portfolio-risk calculations, recovery accounting and isolated-account handling.
- BIP-1 foundations: Support for provider-backed market configuration, provider-fee accounting and related queries.
Happy trading!
