Risk Control Measures During Initial Trading
To protect traders from extreme volatility during the first minutes of trading, OKX implements strict risk controls for newly listed assets like SOPH.
Order Restrictions (First 5 Minutes)
During the initial five minutes post-launch, the following rules apply:
- Market orders are disabled — Only limit orders are allowed.
- Maximum order size: $10,000 per limit order.
- Net position cap: Each user’s net long or short exposure cannot exceed $10,000.
These restrictions are automatically lifted after the first five minutes of continuous trading.
Price Capping Mechanisms
To prevent wild price swings, OKX employs dynamic price limits based on two phases: pre-index and index-based pricing.
Phase 1: Pre-Index Price Limits (When Index Is Unavailable)
In the early moments when a stable market index isn't yet established:
- First minute: Buy orders cannot exceed the call auction clearing price × (1 + H). Sell orders have no minimum.
- Minutes 1 to N: Buy orders capped at the previous minute’s closing price × (1 + H).
- After N minutes: No price limits apply until index availability.
Phase 2: Index-Based Price Limits
Once a reliable external index is available:
First 10 minutes after listing:
- Buy cap: Index × (1 + X)
- Sell floor: Index × (1 – X)
After 10 minutes:
- Buy cap: Min[Max(Index, Index × (1 + Y) + average premium over last 2 minutes), Index × (1 + Z)]
- Sell floor: Max[Min(Index, Index × (1 – Y) + average premium over last 2 minutes), Index × (1 – Z)]
Note: Parameters H, X, Y, Z, and N are adjustable by OKX at any time without prior notice to maintain market integrity.
Understanding the Call Auction Mechanism
OKX uses a call auction model to launch new trading pairs like SOPH/USDT. This system collects buy and sell orders over a fixed period (in this case, one hour) and calculates a single opening price that maximizes tradable volume.
Key Rules During Call Auction
- Buy order cap per user: $50,000 total value.
- Final 5 minutes: Only limit orders allowed; no modifications or cancellations permitted.
- Opening price determination: Based on order book equilibrium — not influenced by external inputs.
While OKX displays an “opening price” provided by the Sophon project team for informational purposes, this value is not binding and does not affect the actual auction outcome. It reflects the team's valuation perspective but plays no role in trade execution.

Frequently Asked Questions (FAQ)
Q: What is the purpose of the call auction?
A: The call auction ensures fair price discovery by collecting all buy/sell interest before trading starts. It reduces manipulation risks and creates a balanced starting point for continuous trading.
Q: Can I trade SOPH immediately when deposits open?
A: No. Deposits open on May 23, but trading begins only after the call auction ends on May 28 at 9:00 PM (UTC+8).
Q: Why are market orders disabled at launch?
A: To prevent slippage and flash crashes caused by sudden demand spikes, market orders are restricted initially. This protects traders from unfavorable fills.
Q: Is there a maximum amount I can buy during the call auction?
A: Yes. Each user is limited to a maximum of $50,000 worth of buy orders during the call auction phase.
Q: Does the project team’s suggested opening price affect trading?
