In futures trading, order failures or unexecuted trades can occur. Understanding the reasons behind these failures helps traders adjust strategies and improve success rates. This article summarizes the primary causes of order failures in futures trading and provides solutions.

Insufficient Margin

Insufficient available margin is a common cause of order failure, which may result from:

  1. Other pending orders occupying available margin, preventing execution of the current order.

  2. Order amount exceeding the maximum position size.

  3. Low-leverage trades requiring higher margin balances.

💡Solution: Increase margin or adjust leverage to ensure sufficient funds.

Position Limits

Orders may fail due to exceeding position limits, caused by:

  1. Take-profit/stop-loss orders or reverse position openings requiring excessive margin for net exposure.

  2. Order notional value exceeding the maximum limit for the trading pair (varies by leverage and trading pair).

💡Solution: Verify position limits for the trading pair to ensure compliance. Refer to 「 LBank Trading Rules」.

Below Minimum Order Requirements

Each futures contract type has minimum order quantity or amount requirements. Orders below these thresholds cannot be submitted.

Reduce-Only Order Restrictions

When the “Reduce-Only” option is selected, orders may be rejected due to:

  1. Order direction matching the existing position.

  2. Order direction being opposite but exceeding the current position size.

💡Solution: Confirm the position’s direction and size before placing the order.

FOK Order Non-Execution

Fill-or-Kill (FOK) orders require immediate full execution, or they are canceled. If market conditions cannot fulfill the order, it is rejected and not recorded in order history.

💡Solution: Use limit or market orders to increase execution likelihood.

Price Matching Failure

Orders may fail due to unmet price conditions, including:

  1. Market price not reaching the set take-profit/stop-loss trigger price.

  2. Order price deviating significantly from market price, failing to match market depth.

  3. Large positions resulting in partial fills.

💡Solution：Set more reasonable trigger prices or use market take-profit/stop-loss orders.

Margin Review Failure

Take-profit/stop-loss orders undergo two margin reviews (before placement and execution). If available margin is insufficient at execution (e.g., due to losses or withdrawals), the order will show as “expired.”

💡Solution：Ensure sufficient margin is available at execution.
