Bid-Ask Spread: The Hidden Fee You Pay Every Trade

Learn what the bid-ask spread is, why it widens, and how spread affects your break-even, win rate, and short-term trading strategies.

The spread is the gap between the highest buyer and lowest seller. You pay it on every round trip.

Bid and ask bands with a highlighted spread gap.

Why spreads widen

Low liquidity, volatility spikes, and off-peak hours all widen spreads.

Spread impact on break-even

If your target is small, spread can consume most of your edge. Costs pile up fast on short-term trades.

How to trade with spread in mind

  • Prefer liquid pairs
  • Avoid dead hours
  • Use limit orders when appropriate
