What is swing point?

What it means

The definition requires a lookback parameter — commonly two or three bars either side. That parameter is not cosmetic: a two-bar swing identifies many minor turns, while a five-bar swing identifies only major ones, and the same chart produces completely different structure depending on which you choose.

Why it matters

Swing points are where stops go, which is why they are also where liquidity pools. Placing your own stop at the obvious swing point puts it exactly where everyone else's is, and a few points beyond it is meaningfully safer for the cost of slightly wider risk.

What this changes in practice

They also carry a confirmation delay that is easy to overlook in a backtest. A swing high is not confirmed until the required number of bars has closed after it, so a system trading swing points is always acting on information that is several bars old. A replay that treats the swing as known at the moment it formed is measuring a strategy nobody can trade.
