Enhanced Trading Access and Features
Following the launch of the SPK/USD orderbook, core functionalities including Buy/Sell and Convert will become available approximately two hours later. This brief delay ensures market stability and allows for sufficient liquidity buildup during the initial phase of trading.
The introduction of SPK aligns with OKX’s ongoing commitment to expanding access to innovative blockchain projects that drive utility in decentralized finance. As part of this effort, users gain early exposure to high-potential assets integrated within scalable financial frameworks.
Spot Market Opening Risk Control Measures
To safeguard traders from excessive volatility during the launch window, OKX has implemented temporary risk control protocols that apply during the first minutes of trading.
Order Value Limits
For the first five minutes after trading commences:
- Each limit order is capped at a maximum value of 10,000 USD.
- These restrictions are automatically lifted after the initial 5-minute period, allowing unrestricted order sizes thereafter.
This measure helps prevent sudden price swings caused by oversized trades and promotes a more balanced market entry for all participants.
Price Limit Mechanisms
Due to the absence of an established market equilibrium at launch, OKX employs dynamic price control rules based on either closing prices or index prices, depending on data availability.
Closing Price-Based Limits (Initial Phase)
When no stable index price is available, the system uses recent transaction data to calculate allowable bid and ask ranges:
- First minute of listing:
Maximum bid price = Call auction execution price × (1 + H)
Minimum ask price = No restriction - From minute 1 to N (until index stabilizes):
Maximum bid price = Previous minute’s closing price × (1 + H)
Minimum ask price = No restriction - After minute N:
No limits applied on either side
Index-Based Limits (Stabilized Phase)
Once a reliable index price is established, the platform transitions to index-referenced controls:
- First 10 minutes after index availability:
Maximum bid = Index × (1 + X)
Minimum ask = Index × (1 – X) - Beyond 10 minutes:
Bid cap adjusts dynamically using:Min[Max(Index, Index × (1 + Y) + Avg premium over last 2 mins), Index × (1 + Z)]
Ask floor adjusts using:Max[Min(Index, Index × (1 – Y) + Avg premium over last 2 mins), Index × (1 – Z)]
OKX reserves the right to modify parameters (N, H, X, Y, Z) or change calculation methodologies in response to real-time market conditions without prior notice. Users are encouraged to monitor live rules via the platform’s official risk information page.
