Understanding the Opening Risk Control Measures
To protect investors from extreme volatility during the initial trading phase, OKX implements specific order and price limits for the first five minutes after spot trading begins.
Order Restrictions
- Market orders are disabled.
- The maximum amount per limit order is $10,000.
- The maximum net position per user is $10,000.
These restrictions are automatically lifted five minutes after trading commences.
Price Limit Rules
The platform uses two methods to calculate price limits, depending on market stability.
Closing Price-Based Limits: Applied when a stable index price is not yet available.
- First minute: Maximum bid price is the call auction’s execution price × (1 + H); no limit on the minimum ask.
- First to Nth minute: Maximum bid becomes the previous minute’s closing price × (1 + H); no limit on ask.
- After Nth minute: No limits on bid or ask prices.
Index-Based Limits: Applied once a stable index is established.
- First 10 minutes: Bid and ask prices are bounded by Index × (1 + X) and Index × (1 – X).
- After 10 minutes: A more complex formula using parameters Y and Z and the average premium from the last two minutes is used.
OKX may adjust parameters (N, H, X, Y, Z) or change calculation methods based on market conditions without prior notice. 👉 View real-time trading rules and updates
The Call Auction Process Explained
The USDG/USDT pair will utilize a call auction mechanism for one hour before continuous trading begins. This process helps discover a fair opening price by collecting buy and sell orders.
Key rules for the call auction:
- The total value of buy orders per user must not exceed $50,000.
- During the final five minutes of the auction, orders can be placed but cannot be canceled or modified.
Following the auction, OKX will display a "project team’s opening price" on the trading chart. This price, provided by the token's project team for informational purposes, does not affect the execution prices determined by the auction.
