Slippage occurs when your order executes at a different price than expected. It can be positive (better price) or negative (worse price).

Causes

  • High volatility — Prices move rapidly between order and execution
  • Low liquidity — Not enough orders at your expected price
  • News events — NFP, rate decisions cause rapid price changes
  • Gaps — Weekend/holiday openings

Types

How to Minimize Slippage

✅ Use limit orders instead of market orders ✅ Avoid trading during high-impact news ✅ Trade during high-liquidity sessions (London/NY) ✅ Choose brokers with fast execution ✅ Use guaranteed stop losses (if available)

Key Points

  • Some slippage is normal and unavoidable
  • ECN brokers typically have less slippage
  • Slippage can work in your favor too
  • Guaranteed stop losses eliminate slippage risk (for a fee)
