Why Is My Binance Fill Price Different from the Displayed Price?

Why Prices Do Not Match

Many users on the Binance Official Website or Binance Official App notice that their fill price differs from what they saw on screen. This is not platform manipulation - it is a universal market phenomenon called slippage. Apple users see the iOS Installation Guide.

What Is Slippage?

Slippage is the difference between the expected price and the actual execution price. Between clicking "Buy" and order execution (milliseconds to seconds), the market price may have moved. Example: you see BTC at 60,000, but your fill is 60,050 - that 50 USD gap is slippage.

Causes

Market volatility: Crypto prices can move tens or hundreds of dollars per second. Market orders: "Buy at any price now" means your order eats through multiple price levels in the order book if volume at the best price is insufficient. Thin order books: Low-volume altcoins have wide spreads and less depth, amplifying slippage even for small trades. Network latency: Delay between your device and the server allows price changes.

How to Reduce Slippage

Use limit orders: Set your maximum acceptable price - you will never fill worse than your limit. Downside: may not fill at all if price moves away. Split large orders: Break big trades into smaller pieces to reduce market impact. Trade liquid pairs: BTC/USDT and ETH/USDT have deep books and minimal slippage. Avoid extreme volatility periods: Order books are unstable during crashes/pumps. Set slippage tolerance: Some features like Convert offer slippage protection - orders cancel if slippage exceeds your threshold.

Slippage Across Trading Methods

Spot: Limit orders eliminate slippage entirely. Market orders on major pairs have minimal slippage. Futures: Generally good liquidity, but extreme conditions amplify slippage (affecting stop-loss execution). Convert: Price is locked at quote time (within the validity window), so no additional slippage beyond the built-in spread.

Summary

Price display vs. fill price differences are caused by slippage - a normal market phenomenon. Use limit orders, trade liquid pairs, and avoid market orders during extreme volatility. For everyday small trades, slippage is typically negligible.
