Starting June 17, 2025, at 8:00 PM (UTC+8), OKX will introduce the SPK/USD trading pair in its spot market under the USD trading zone. This strategic addition aims to support the expanding USD-pegged ecosystem and meet growing user demand for diversified digital asset trading options.
The new trading pair will be accessible via Buy/Sell and Convert functions approximately two hours after the orderbook goes live. This phased rollout ensures system stability and provides users with a seamless onboarding experience for this emerging DeFi asset.
Enhanced Risk Management for New Listings
To safeguard traders during the initial volatility phase of new token launches, OKX has implemented a comprehensive risk control framework for SPK/USD spot trading.
Order Amount Limits
For the first five minutes after market opening, all limit orders will be capped at a maximum of $10,000 per order. This restriction helps prevent large, potentially manipulative trades from destabilizing the price during early trading. After this brief period, the cap will be lifted, allowing full trading flexibility.

Dynamic Price Capping Mechanism
OKX employs a two-stage price limiting system to ensure orderly trading, especially when market data is still stabilizing.
Phase 1: Based on Closing Price (When Index Is Unavailable)
During the initial phase—when a reliable index price isn't yet available—OKX uses historical closing prices to determine valid bid and ask ranges:
- First minute after launch: Buy orders cannot exceed the auction clearing price multiplied by (1 + H). Sell orders face no minimum restrictions.
- Minutes 1 to N (before stable index): Buy limits are set at the previous minute’s closing price × (1 + H). Selling remains unrestricted.
- After minute N: Both buying and selling are fully unrestricted.
Phase 2: Index-Based Pricing (When Index Becomes Available)
Once a stable index price is established, OKX switches to an advanced index-based mechanism:
First 10 minutes after launch:
- Maximum buy price = Index × (1 + X)
- Minimum sell price = 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)]
These dynamic parameters (N, H, X, Y, Z) may be adjusted in real time based on market conditions. OKX reserves the right to modify these settings without prior notice to maintain market integrity.
