If your stock order didn’t go through, it can feel frustrating—but order rejections are usually caused by specific, preventable conditions related to market rules, account status, or order setup. Below is a clear breakdown of the most common reasons a stock order fails and how to fix them.
1. Insufficient Buying Power or Available Cash
One of the most common reasons for a failed order is not having enough available funds.
Even if your account shows a balance, it may not be “settled” or available for trading.
Common causes:
Funds are still pending deposit settlement
You are trying to buy more than your available cash
You included estimated fees or market fluctuations that exceed your balance
How to fix it:
Check your available buying power, not just your total balance
Wait for deposits to fully settle
Reduce the order size or increase funds
2. Market Is Closed or Trading Is Restricted
Stock markets operate on specific schedules.
U.S. market hours:
9:30 a.m. – 4:00 p.m. ET (regular trading)
Outside these hours:
Orders may be delayed
Some securities may not support extended-hours trading
How to fix it:
Place your order during market hours
Confirm whether the stock supports pre-market or after-hours trading
3. Invalid Order Type or Price Conditions
Order type settings can cause failures if market conditions don’t match your instructions.
Examples:
A limit order set far above or below market price
A limit order that the market never reaches
Attempting to buy fractional shares where not supported
How to fix it:
Adjust your limit price closer to the current market price
Try a market order if immediate execution is acceptable
Confirm fractional share availability for the stock
4. Insufficient Share Quantity (for Sell Orders)
Sell orders fail when the system detects you don’t own enough shares.
Common causes:
Shares are still settling from a recent purchase
Partial fills from previous trades
Incorrect quantity entered
How to fix it:
Review your holdings carefully
Ensure shares are fully settled and available for sale
Enter exact share quantity instead of estimated amounts
5. Account Verification or Compliance Restrictions (KYC)
Regulatory requirements may block trading if your account is not fully verified.
Possible issues:
Incomplete identity verification (KYC)
Pending suitability or brokerage approval
Missing required personal information
How to fix it:
Complete all required KYC steps in the app
Ensure your profile information is accurate and up to date
6. Market or Security-Specific Restrictions
Some stocks or ETFs may have temporary or permanent trading restrictions.
Examples:
Halted trading due to volatility
Limited availability on certain brokerage platforms
Restricted securities due to regulatory rules
How to fix it:
Wait for trading to resume
Confirm the asset is supported on the platform
7. Technical or Connectivity Issues
Occasionally, orders fail due to app or network issues.
Possible causes:
Poor internet connection
Outdated app version
Session timeout or login expiration
How to fix it:
Refresh or restart the app
Update to the latest version
Log out and log back in
Try again on a stable connection
What to Do If Your Order Still Fails
If you’ve checked all the above and your order still does not go through:
Review the specific error message in the app
Verify your available buying power and order details
Try simplifying the order (market order, smaller size)
Contact support through the in-app chat with:
Stock ticker
Order type
Timestamp
Screenshot of the error (if available)
Summary
Stock order failures are typically caused by one of the following:
Insufficient funds or unsettled cash
Market hours restrictions
Order pricing conditions
Account verification status
Security or trading limitations
Temporary technical issues
Understanding these factors helps you quickly identify the issue and successfully place future trades.
