Risk Management: Spot Trading Controls at Launch
To safeguard users from extreme volatility during the initial trading phase, OKX will enforce temporary risk control measures for the first five minutes after SPK/USDT spot trading begins.
Order Restrictions (First 5 Minutes)
- No Market Orders Allowed
Only limit orders will be accepted to prevent slippage and erratic price movements. - Maximum Limit Order Size: $10,000 per order
This cap ensures no single large trade dominates the order book. - User Net Position Limit: $10,000 maximum
Individual traders cannot hold a net long or short position exceeding this threshold during the cooling period.
These restrictions will be automatically lifted five minutes after market open, allowing full trading functionality.
Price Capping Mechanism: Ensuring Market Stability
Given the potential for price instability when a new token launches, OKX employs a dynamic price capping system that adapts based on market data availability.
Phase 1: Based on Closing Price (When Index Is Unavailable)
During the earliest moments of trading — when a reliable external price index isn’t yet established — OKX uses recent closing prices to determine valid price bands:
- First Minute: Buy orders capped at auction clearing price × (1 + H); sell orders have no lower bound.
- Minutes 1 to N: Buy limit = previous minute’s close × (1 + H); sell orders remain uncapped.
- After Minute N: No price limits apply once sufficient data stabilizes the market.
Phase 2: Index-Based Price Capping (When Stable Index Available)
Once a reliable market index is established (typically within minutes), OKX switches to an index-driven model:
First 10 Minutes Post-Launch:
- Maximum buy price: Index × (1 + X)
- Minimum sell price: Index × (1 – X)
After 10 Minutes:
- Buy cap adjusts dynamically using:
Min[Max(Index, Index × (1 + Y) + avg premium over last 2 min), Index × (1 + Z)] - Sell floor uses:
Max[Min(Index, Index × (1 – Y) + avg premium over last 2 min), Index × (1 – Z)]
- Buy cap adjusts dynamically using:
⚠️ Note: Parameters H, X, Y, and Z are adjustable at OKX’s discretion based on real-time market conditions. Updates will be applied without prior notice to maintain platform integrity.
Understanding the Auction Mechanism
OKX will use a one-hour centralized auction prior to official trading to establish fair initial pricing and reduce manipulation risks.
How It Works
During the auction window:
- Users submit buy and sell orders at their desired prices.
- The system aggregates all orders and calculates a reference opening price that maximizes tradable volume.
- This process promotes price discovery while minimizing front-running and spoofing.
Key Auction Rules
- Buy Order Cap: Each user limited to a maximum of $50,000 in total buy orders.
Final 5 Minutes:
- Only limit orders allowed.
- No modifications or cancellations permitted.
This lock-in period ensures order integrity and prevents last-second manipulative behavior.
It’s important to note: The final opening price used by OKX may be influenced by the project team’s suggested valuation based on USDS ecosystem metrics. While this value serves as a benchmark, it does not override the auction-determined equilibrium price.
