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

Type Description Example
Positive Better price Want 1.0850, get 1.0848
Negative Worse price Want 1.0850, get 1.0852
Zero Exact price Want 1.0850, get 1.0850

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)
