Understanding the New Listing Risk Control Measures
To safeguard users from the high volatility often associated with new token listings, OKX will implement several protective measures during the initial trading period.
Initial Order Restrictions
For the first five minutes after trading begins, the following restriction will be in place:
- A maximum limit order value of $10,000 per order.
This restriction will be automatically lifted five minutes after the trading session starts.
Dynamic Price Limit Rules
The platform employs a dynamic system of price limits to maintain market stability. The mechanism used depends on the availability of a stable index price for the asset.
When a Stable Index Price is Not Available:
Initially, the system will use a limit mechanism based on the closing price.
| Phase | Buy Order Upper Limit | Sell Order Lower Limit |
|---|---|---|
| First minute after listing | Auction Price × (1 + H) | No limit |
| Minutes 1 to N (before index is available) | Previous minute's closing price × (1 + H) | No limit |
| After minute N (before index is available) | No limit | No limit |
When a Stable Index Price Becomes Available:
Once a reliable index price is established, the system will switch to an index-based limit rule.
| Phase | Buy Order Upper Limit | Sell Order Lower Limit |
|---|---|---|
| First 10 minutes after listing | Index × (1 + X) | Index × (1 – X) |
| 10+ minutes after listing | Complex formula based on Index, a percentage band (Y, Z), and a 2-minute premium average. | Complex formula based on Index, a percentage band (Y, Z), and a 2-minute premium average. |
Please note: The parameters (N, H, X, Y, Z) and the active limit rule are subject to change based on real-time market conditions without prior notice. For the most current details, we recommend you 👉 view the real-time trading rules.
