Slippage in trading is when your order executes at a different price than you intended, usually due to fast market movements, low liquidity, or large order sizes, resulting in a worse (negative) or sometimes better (positive) price than quoted
common in volatile markets like forex or during major news events. It's the difference between the expected price and the actual execution price, a normal part of dynamic markets that can be managed by using limit orders or trading during active hours.
Why Slippage Happens
- Volatility: Rapid price changes mean the quoted price is stale by the time your order reaches the market.
- Low Liquidity: Insufficient buyers or sellers at your desired price level, especially in thinly traded assets or off-hours.
- Large Orders: Big market orders can absorb available volume at one price, forcing the rest to fill at progressively worse prices (stacking).
- Market Gaps: Prices jump from one level to another (e.g., overnight), bypassing your requested price entirely.
Types of Slippage
- Negative: You get a worse price (e.g., buy higher, sell lower than intended).
- Positive: You get a better price (e.g., buy lower, sell higher) – less common but possible.
- Zero: Order fills exactly as requested (no slippage).
How to Reduce Slippage
- Use Limit Orders: Specify the maximum price you'll pay (buy) or minimum you'll accept (sell).
- Trade Liquid Assets: Focus on high-volume stocks, major currency pairs (Majors in Forex).
- Trade During Peak Hours: Volatile times (news) increase risk; calm, active hours reduce it.
- Avoid Gaps: Be cautious with orders held overnight or during major news.
