Users are encouraged to deposit their funds ahead of the call auction to participate fully in the price discovery process. The phased rollout ensures a smooth transition into open market trading while minimizing volatility risks.
Understanding the Call Auction Mechanism
To promote fair pricing and reduce manipulation during the initial trading phase, OKX employs a call auction mechanism for new token listings. For SPK/USDT, this one-hour session allows traders to place limit orders before the official market open.
During the call auction:
- Orders are collected but not executed.
- A reference opening price is calculated based on supply and demand.
- The final price aims to maximize tradable volume at a single equilibrium point.
This system benefits all participants by reducing slippage and preventing sudden price spikes caused by market rushes.
Key Rules During Call Auction
- Buy Order Cap: Each user can place up to $50,000 worth of buy orders.
- Final 5 Minutes Restrictions: No order modifications or cancellations are allowed in the last five minutes—only new limit orders permitted.
These safeguards help maintain order integrity and discourage speculative behavior. After the auction concludes, trading commences at the determined opening price.
Risk Management at Launch
Given the inherent volatility associated with newly listed tokens, OKX implements temporary risk controls during the first five minutes of live spot trading.
Order Restrictions
- No Market Orders: To prevent excessive slippage, market orders are disabled.
- Maximum Limit Order Size: Each order capped at $10,000.
- Net Position Limit: Individual net long position limited to $10,000.
These measures will be automatically lifted after five minutes, allowing unrestricted trading thereafter.
Price Band Controls
In cases where real-time index data isn’t yet stable, OKX applies dynamic price limits based on either:
Pre-Index Phase (Using Closing Price)
| Timeframe | Buy Order Cap | Sell Order Floor |
|---|---|---|
| First minute | Auction close × (1 + H) | No restriction |
| Minutes 1–N (index pending) | Prior minute close × (1 + H) | No restriction |
| After N minutes | No restriction | No restriction |
Post-Index Phase (Using Index Price)
| Timeframe | Buy Order Cap | Sell Order Floor |
|---|---|---|
| First 10 minutes | Index × (1 + X) | Index × (1 – X) |
| After 10 minutes | Min[Max(Index, Index×(1+Y)+avg premium), Index×(1+Z)] | Max[Min(Index, Index×(1–Y)+avg premium), Index×(1–Z)] |
Note: Parameters H, X, Y, Z, and N may be adjusted dynamically by OKX without prior notice based on market conditions.
This layered approach ensures price stability during critical early moments while adapting to evolving market data.
