Summary: This article explores the time restrictions in OKX perpetual contract trading, covering four key aspects: trading hours, order placement windows, position holding periods, and order cancellation deadlines.
1. Trading Hours Limitations
The OKX perpetual contract market operates 24/7, but this doesn't mean completely unrestricted access. To ensure market stability and protect traders, OKX implements specific trading windows:
- Daily Settlement Pause: Trading halts for 10 minutes before a new trading day begins to facilitate settlement. Orders executed during this window count toward the previous day’s activity.
- Timeout Protection: Inactive traders are automatically logged out to prevent unintended positions.

2. Order Placement Rules
OKX enforces dynamic order restrictions to maintain market integrity:
- Volatility Controls: During extreme price swings, OKX may temporarily suspend orders to prevent manipulation or disorderly trading.
- Directional Limits: Example: Pausing long-position orders during sharp downturns.
- Minimum Requirements: Orders must meet set size thresholds and price ranges to ensure fair access.
Example: A $10 BTC order might be rejected if it deviates from the current price band.
3. Position Holding Periods
Perpetual contracts aren’t truly "perpetual" due to:
- Expiry-Based Caps: Each contract has a maximum holding period tied to its settlement cycle.
- Forced Liquidation: Positions exceeding this limit are auto-closed, regardless of profit/loss.
- Market Adjustments: OKX may shorten holding periods during high volatility to mitigate risk.
Pro Tip: Monitor contract details and use stop-loss orders to avoid unwanted liquidations.
4. Order Cancellation Deadlines
- Irreversible Executions: Once filled, orders cannot be canceled.
- Pre-Execution Edits: Modify pending orders if market conditions change.
Why This Matters: Prevents traders from spamming cancellations to exploit price gaps.
