# Summary of Failed Orders in Futures Trading
When trading in the crypto futures market, there are several reasons why your order may fail to be placed or remain unfilled. Here are some possible reasons to consider:
Reasons for Failed Orders:
* Insufficient Margin Balance: Your margin balance may need to be more to open the position due to other open orders using the margin or the order amount exceeding the position amount. Adjusting the leverage or closing other positions could solve this issue.
* Limited Position: For stop-limit orders, the margin balance of the net position may not be enough due to the exceeded amount of the reverse position.
* Minimum Contract Quantity: Some contracts have specific minimum contract quantities.
* \[Reduce-only] Order: You cannot place a reduce-only order if there is no reverse position.
Reasons for Unfilled Orders:
* No Matching Price: The market price may not meet your set price, particularly in Stop-limit orders.
* Deviating from Market Price: The order may deviate significantly from the market price, resulting in no matching orders in the market depth pool.
* Margin Check Failure: The system will conduct double margin checks before placing and filling the order for Stop Limit and Stop Market orders. If there is a loss or inadequate margin balance, the order status will be shown as expired.
