Price Limit Rules
When index prices are unstable, OKX uses a closing-price-based limit mechanism:
| Phase | Buy Order Max Price | Sell Order Min Price |
|-------|----------------------|-----------------------|
| First 1 minute | Call auction price × (1 + H) | No limit |
| Minutes 1–N (pre-index) | Previous minute’s closing price × (1 + H) | No limit |
| Post-N minutes (pre-index) | No limit | No limit |
Once index prices stabilize, index-based limits apply:
| Phase | Buy Order Max Price | Sell Order Min Price |
|-------|----------------------|-----------------------|
| First 10 minutes | Index × (1 + X) | Index × (1 – X) |
| After 10 minutes | Dynamic adjustment based on index and premium averages |
Parameters (N, H, X, Y, Z) are subject to change without prior notice.
