Why did my contract order fail?

In contract trading, orders may fail for the following reasons:

1、 Insufficient Margin Balance

Your margin may be occupied by other pending orders, or the order amount exceeds the position limit.

Lower leverage requires higher margin. Suggestion: Try increasing margin or reducing leverage before placing orders.

2、 Order Exceeds Position Size Limit

Each currency has a maximum openable quantity and available leverage. Orders exceeding this range will be rejected.

Position limits vary by currency and leverage. Please ensure orders do not exceed the maximum position limit when placing orders.

3、 Order Does Not Meet Minimum Notional Value

Each currency has minimum trading amount requirements. Please refer to the actual amount prompted on the trading interface.

4、 Order Type Causes Order Failure

FOK (Fill or Kill) orders failed to execute immediately, resulting in failure.

Maker orders failed to execute as pending orders, resulting in failure.

5、 Too Many Pending Orders, Exceeding Limit

Single U-margined contract currency: Maximum 200 orders can be placed simultaneously (including open conditional orders).

All U-margined contracts combined: A single user can place a maximum of 10,000 orders simultaneously.

Solution: If orders exceed the limit, please cancel some pending orders before attempting to place new orders.

6、Too Many Open Conditional Orders

Each U-margined contract can have a maximum of 10 conditional orders (including stop loss orders, take profit orders, etc.).

Solution: If the limit is reached, please cancel some conditional orders before placing new orders.

7、Insufficient Market Liquidity, Market Orders Cannot Fully Execute

When market liquidity is low, market orders may not fully execute, or their prices exceed the system’s allowed market price upper/lower limit ratio (PERCENT_PRICE filter limit), causing order failure.

Solution: Please check market depth, or try using limit orders.

8、 Order Price Exceeds Market Range

Limit buy orders: Price cannot be higher than (1 + upper limit ratio) × current mark price.

Limit sell orders: Price cannot be lower than (1 - lower limit ratio) × current mark price.

Solution: Please adjust the order price to meet market range requirements.

9、Order Price Differs Too Much from Market Price

Order price is too high or too low, cannot find matching counterparties in the market depth pool, or position is too large, can only partially execute.

Solution: Adjust the order price to be closer to the market price to improve execution probability.

10、Failed Margin Check (Applicable to Limit Stop Loss Orders & Market Stop Loss Orders)

When placing limit stop loss orders or market stop loss orders, the system performs two margin checks:

Check available margin in the account when placing the order.

Check available margin again when the order is triggered.

If the account margin is insufficient after triggering (such as transferring funds from the contract account), the order will fail and be cancelled.

Summary: How to Avoid Contract Order Failure?

Check margin balance to ensure sufficient funds to support trading.
Confirm position size and leverage limits to avoid exceeding exchange-set ranges.
Ensure order amounts meet minimum trading requirements.
Choose appropriate order types to avoid FOK or Maker order execution failures.
Avoid placing too many orders and reduce open conditional orders.
Use limit orders when liquidity is low to improve execution rate.
Adjust order prices to meet market range requirements.
Maintain sufficient account margin to avoid failure due to insufficient margin when stop loss orders are triggered.
