Binance Futures error codes explained

What Are Binance Futures Error Codes?

When trading on Binance Futures, users may encounter various error codes that prevent their orders from executing. These codes are standardized messages from Binance’s API or web interface designed to inform traders about the exact reason an action failed. Understanding these codes is essential to avoid repeated mistakes and maintain smooth trading operations. Each code corresponds to a specific issue, such as insufficient margin, invalid parameters, or rate limiting. Recognizing the meaning behind codes like -4001, -2010, or -1102 helps traders resolve issues quickly without contacting support.

Common Binance Futures Error Codes and Their Meanings

Some of the most frequently seen error codes include:

• -4001: 'Order would trigger immediately.' This occurs when your stop-loss or take-profit order price is set at a level that would execute instantly based on current market conditions.
• -2010: 'Account has insufficient balance for requested action.' This means your available margin is too low to open or maintain a position.
• -1102: 'A mandatory parameter was not sent, or a parameter was not valid.' This happens when a required field like quantity, symbol, or side is missing or incorrectly formatted.
• -1121: 'Invalid symbol.' This indicates the trading pair (e.g., BTCUSDT) doesn’t exist or is misspelled in the request.
• -2021: 'Order would immediately match and take.' This appears when placing a limit order that would execute against existing orders in the order book immediately—common in high-frequency trading bots.

  How to Fix Error Code -2010: Insufficient Balance

  This error means your cross or isolated margin account lacks the necessary funds to open or adjust a position. To resolve it:
• Check your Available Balance in the Futures wallet under “Assets.”
• Ensure you’re not using leverage that exceeds your margin capacity—use the Margin Calculator in Binance’s interface.
• If using isolated margin, verify that the selected symbol has enough allocated margin—go to “Position” > select symbol > click “Edit Margin.”
• Transfer more funds from your spot wallet to Futures if needed via the Internal Transfer tab.

  Step-by-Step Guide to Resolve Error -1102: Missing or Invalid Parameter

  This error typically appears in API-based trading. Follow these steps to fix it:
• Review your API request payload—ensure all required fields like symbol, side, type, and quantity are present.
• Confirm that symbol uses uppercase (e.g., BTCUSDT, not btcusdt).
• Validate side is either BUY or SELL—not lowercase or misspelled.
• Check quantity format—it must be a string or float with correct precision (e.g., 0.001 for BTC, not 0.00123456).
• Use Binance’s API Test Endpoint (https://testnet.binance.vision) to simulate requests before going live.

  Understanding Rate Limit Errors Like -2014 and -2015

  These codes appear when you exceed Binance’s API call limits:
• -2014: 'API key not found.' Your API key is either invalid or not properly attached in the request header (X-MBX-APIKEY).
• -2015: 'Invalid API-key, IP, or permissions for action.' This means your IP is not whitelisted (if enabled), or the API key lacks Futures trading permissions.To fix:
• Regenerate your API key in Binance Settings if it’s corrupted.
• Enable 'Enable Futures' permission when creating the key.
• Whitelist your IP address in the API management panel if IP restriction is active.

  How to Prevent Order Rejection Due to Price Filters (-1111)

  Error -1111: 'Price * QTY is zero or less' or 'Price is too small' means your limit price violates the symbol’s price filter. Each futures contract has a minimum price precision (e.g., 0.1 for BTCUSDT). To avoid this:
• Fetch the symbol’s filters via Binance’s Exchange Information endpoint (/fapi/v1/exchangeInfo).
• Look for priceFilter in the JSON response—it shows minPrice, maxPrice, and tickSize.
• Ensure your limit price is a multiple of tickSize (e.g., 60000.1, 60000.2 for BTCUSDT if tickSize is 0.1).
• Round your price using Math.floor(price / tickSize) * tickSize in your code to comply automatically.

  Frequently Asked Questions

  Q: Why do I get error -1100: 'Illegal characters found in a parameter'?This occurs when your request includes non-numeric characters in numeric fields like quantity or price. For example, sending '1.0abc' instead of '1.0'. Always validate input types—use string-to-float conversion only after sanitizing the input.

  Q: What does error -4061 mean in Binance Futures?-4061 means 'Order's notional must be greater than X and less than Y.' Each symbol has a minimum and maximum notional value (price × quantity). For BTCUSDT, the minimum might be $5. Adjust your order size to stay within these bounds.

  Q: Can I get error -1121 even if the symbol is correct?Yes—if the symbol is correct but the contract type is wrong. For example, using 'BTCUSDT_210625' (delivery futures) instead of 'BTCUSDT' (perpetual). Always confirm you’re trading the correct contract type in your API or UI.

  Q: How do I know if my API key is restricted from Futures?Check your API key permissions in Binance under “API Management.” If “Futures” is unchecked, you’ll see -2015 when placing orders. Enable it, save, and wait 5 minutes for propagation.
