Dear OKX Users,
To enhance trading system stability and provide a faster, more efficient trading experience, OKX will adjust the pending order limit for trading symbols starting August 14, 2023, at 4:00 PM (UTC+8). After this update, each trading symbol will support a maximum of 500 pending orders.
Key Adjustments:
- Per-Symbol Limit: 500 pending orders (e.g., BTC-USDT-SWAP perpetual contracts, BTC-USDT-230707 futures contracts, and BTC-USDT spot trading will each have separate limits).
- Existing Orders: Current orders exceeding the limit remain active but must be filled or canceled before new orders for the same symbol can be placed.
- Unchanged Rules: Options trading limits remain unaffected.
Order Types Included in the Limit:
- Limit orders
- Market orders
- Post-only orders
- FOK (Fill-or-Kill)
- IOC (Immediate-or-Cancel)
- Optimal limit IOC
- Take-profit/Stop-loss (TP/SL)
Orders triggered by:
- Trigger orders
- Trailing stops
- Arbitrage strategies
- Iceberg orders
- TWAP (Time-Weighted Average Price)
