Order failures can be diagnosed by looking at the specific error messages. Open the Binance Official Website and check the trading page for specific prompts. The Official Binance APP also displays detailed error codes. If you need to switch regions, refer to the Binance App Download guide. Below are the categories of common issues.
Category 1: Insufficient Balance
Issue 1: Not Enough USDT
You want to buy 100 USDT worth of BTC, but your Spot Wallet only contains 80 USDT.
How to Fix:
- Check your "Spot Wallet" balance.
- If your USDT is in another wallet (e.g., Futures or Earn), you must "Transfer" it to the Spot Wallet.
- Purchase more USDT via C2C to top up your Spot balance.
Issue 2: Insufficient Trading Fees
If you place an order for exactly 100 USDT and the fee is 0.1 USDT, but your balance is exactly 100.05 USDT, the order might fail because the total required (100.1) exceeds your balance.
How to Fix: Input a slightly lower amount (e.g., 99.9 USDT) to leave room for the transaction fee.
Issue 3: Precision Errors
You entered 0.0000123 BTC, but the market's minimum precision is 0.00001 BTC.
How to Fix: Adjust the value to match the required precision.
Category 2: Network Issues
Issue 1: Network Disconnection
Unstable Wi-Fi or mobile data while placing an order:
- The button keeps spinning without responding.
- The app reports "Network Exception."
How to Fix:
- Check your internet connection.
- Switch between Wi-Fi and 4G/5G data and try again.
- Wait a few seconds and retry.
Issue 2: API Timeout
Binance servers are under high load:
- "Request Timeout."
- "Server Busy."
How to Fix: Wait a few seconds and try again. This occasionally happens during periods of extreme market volatility.
Category 3: Limits
Issue 1: Daily Trading Limits
Unverified users (those who haven't completed KYC) have very low daily trading limits (often just a few hundred USDT).
How to Fix: Complete the Identity Verification (KYC) process.
Issue 2: Per-Order Limits
Certain coins have minimum or maximum order size restrictions:
- Minimum order is often 5 USDT.
- Maximum order depends on your account level.
How to Fix: Ensure your order size is within the allowed range.
Issue 3: Position Limits
Futures trading has position caps. Beginners might occasionally trigger these limits when scaling into a position.
How to Fix: Reduce the position size or adjust your leverage settings.
Category 4: Risk Control
Issue 1: Account Restricted
Please refer to the "Account Restricted" specialized guide for details.
Issue 2: Abnormal Orders
If you try to place a limit order far below the market price:
- e.g., Buying 1 BTC for 50 USDT when the market price is $70,000.
- The system flags this as an "Abnormal Order."
How to Fix: Set a reasonable price relative to the current market.
Issue 3: Price Ceiling/Floor
Some smaller altcoins have daily price movement limits (Circuit Breakers).
How to Fix: Wait until the restriction is lifted or the market stabilizes.
Category 5: Account Verification
Issue 1: KYC Incomplete
Prompt: "Please complete identity verification first."
How to Fix: Go through the KYC process.
Issue 2: Risk Assessment Required
New users may be required to complete a "Risk Assessment Questionnaire" before their first trade.
How to Fix: Complete the 5-minute survey within the App.
Issue 3: Terms of Service Update
Binance occasionally updates its Terms of Service and requires users to re-accept them.
How to Fix: Review and accept the updated terms.
Category 6: Trading Pair Issues
Issue 1: Delisted Trading Pair
Certain small coins are delisted, and their trading pairs disappear.
How to Fix: Immediately sell these assets back to USDT (if still possible) or withdraw them to an external wallet.
Issue 2: System Maintenance
Binance occasionally puts a specific trading pair under maintenance.
How to Fix: Check the official announcements for recovery times.
Troubleshooting Checklist
| Step | Checkpoint |
|---|---|
| 1 | What exactly is the error message? |
| 2 | Is the balance sufficient? |
| 3 | Is the internet connection stable? |
| 4 | Is KYC verification complete? |
| 5 | Is the account restricted? |
| 6 | Is the trading pair active? |
Follow these steps in order.
"The Buy Button Is Greyed Out"
A greyed-out button usually indicates:
- Zero balance.
- Invalid input amount.
- An unsupported or inactive trading pair.
- Account restriction.
- KYC is not yet complete.
- Terms of Service have not been accepted.
Hover your mouse over the button to see the specific reason, or enter a valid amount to activate it.
Common "Beginner Only" Mistakes
Mistake 1: Using Futures Balance for Spot Trading
The Futures and Spot wallets are separate. Transfer your funds first.
Mistake 2: Buying the "Reverse Pair"
Searching for BTC/USDT but accidentally trying to trade a theoretical USDT/BTC pair.
Mistake 3: Invalid Characters
Using full-width characters or non-English commas. Use standard English punctuation.
Mistake 4: Corrupted Browser Cache
Long-term use without clearing cache can lead to JavaScript loading errors. Clear your browser cache.
How to Contact Customer Support
If you have tried all the above and still cannot trade:
- Take a screenshot of the error message.
- Contact the online customer support.
- Provide your UID and the screenshot.
- The support agent will check your account backend.
This usually resolves the issue in 5–10 minutes.
Preventing Order Failures

Mindset
It is perfectly normal for a beginner to fail their first order. Don't get discouraged:

- Fix it and try again.
- The system is not "targeting" you.
- Support is always available to help.
FAQ
Q: Does it mean my order went through if the button keeps spinning?
A: Not necessarily. Check the "Open Orders" or "Trade History" page. It might have been filled, or it might have failed to submit.
Q: Will I be charged twice if I refresh the page?
A: No. Binance has a de-duplication mechanism for order submissions.
Q: What does "Invalid Price" mean?
A: Your limit price is too far from the current market price or exceeds the price filters. Enter a more realistic price.
Q: Can I skip KYC just to test a small trade?
A: No. Identity verification is a mandatory foundation for trading.
