Swing highs
A swing high is a local price peak surrounded by lower prices according to the chosen pivot definition.
Swing lows
A swing low is a local trough surrounded by higher prices according to the chosen pivot definition.
Building structure from swings
Higher highs and higher lows are commonly associated with upward structure. Lower highs and lower lows are commonly associated with downward structure.
Swing significance depends on scale
A small pivot on a 5-minute chart may be invisible on a 4-hour chart. Traders therefore need a consistent timeframe and pivot definition.
Common mistakes
Changing the pivot definition after the fact
Inconsistent swing selection can make structure subjective.
Treating every tiny turn as structural
Minor fluctuations can obscure the larger market structure.
Swing definitions need explicit rules
A swing high can be defined as a local peak with lower highs on each side, and a swing low as a local trough with higher lows on each side. The number of surrounding bars required is a strategy choice.
Changing that lookback changes which pivots qualify, so two traders can legitimately mark different swings on the same chart.
Confirmed swings use future bars
Many pivot algorithms cannot confirm a swing until one or more later candles have formed. The swing is visually located on an earlier candle, but it was not knowable as a confirmed pivot at that earlier moment.
Backtests must respect this confirmation delay to avoid look-ahead bias.
Minor and major swings can coexist
Small swings occur inside larger swings. A sequence that appears bearish on a short horizon can therefore exist inside a broader bullish structure.
A strategy should define which swing scale controls entries, stops or structural labels instead of switching between scales after the fact.
If later candles are required to confirm a swing, the strategy cannot act as though that confirmation existed on the pivot candle itself.
Key takeaways
- Swing highs and lows are local price pivots.
- Sequences of swings help describe directional structure.
- Pivot significance depends on timeframe and definition.
- Consistency is important when evaluating structure historically.
