Understanding Slippage in Trading: Causes, Effects, and Prevention

·

Introduction

Slippage occurs when a trade executes at a different price than expected—common during high market volatility or when using market orders. It arises when large orders can't be filled at the desired price due to insufficient liquidity.

What Is Slippage?

Slippage isn’t inherently positive or negative; it simply reflects the discrepancy between the anticipated and actual execution price. Orders are filled at the best available price from exchanges or market makers, leading to three possible outcomes:

  1. No Slippage: Execution matches the expected price.
  2. Positive Slippage: Execution is more favourable (e.g., buying lower or selling higher).
  3. Negative Slippage: Execution is less favourable (e.g., buying higher or selling lower).
