Spot Trading Opening Rules
Order Limits
To mitigate price volatility risks during launch, OKX implements the following restrictions for the first 5 minutes of trading:
- Limit orders must not exceed 10,000 USD in value.
- Restrictions lift automatically after 5 minutes.
Price Limit Rules
For newly listed cryptocurrencies lacking a stable index price, OKX applies closing price-based limits initially. Once an index price stabilizes, index-based rules take effect.
Closing Price-Based Limits

|--------|---------------------|---------------------|
| First 1 minute | Call auction’s execution 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 |
Index-Based Limits
| Phase | Maximum Bid Price | Minimum Ask Price |
|--------|---------------------|---------------------|
| First 10 minutes | Index × (1 + X) | Index × (1 – X) |
| After 10 minutes | Min[Max(Index, Index (1 + Y) + 2-min avg premium), Index × (1 + Z)] | Max[Min(Index, Index × (1 – Y) + 2-min avg premium), Index × (1 – Z)] |
