Reading Market Structure: Swing Highs and Swing Lows
The alphabet of every chart — swing highs, swing lows, bullish and bearish structure, and how reading structure correctly sets everything else in SMC.
The alphabet of structure
Every chart is a sequence of swing highs and swing lows. When price prints higher highs and higher lows, buyers are in control and structure is bullish. When it prints lower highs and lower lows, sellers dominate. Mixed sequences mean the market is ranging — and ranging markets are where retail accounts go to die.
Structure is the first thing you read because it is the only objective fact on the chart. Indicators repaint; a swing high that has been swept is history that cannot be edited.
Structure sets the context for everything
Structure is the layer beneath all five rules. Rule 1's directional bias is a structure read on the 15-minute; Rule 4's confirmation is a structure break on the 1m/5m. Before you can call a break of structure, you must be able to mark the structure itself — which swing high and which swing low are the current reference points.
Discipline mark-to-market: at any moment you should be able to answer "who is in control right now, and at which level does that change?" If you can't, the chart isn't ready to be traded.
When structure changes, you change
A bullish sequence ends the moment price breaks the swing low that anchored it — that break is a Change of Character, the first crack covered in the next lesson. A bearish sequence ends with the break of its anchoring swing high.
Structure shifts are binary events, not gradual feelings. The discipline edge comes from being wrong quickly: one flip on real evidence costs a fraction of what defending a dead structure costs.
Common questions
What counts as a swing high versus just a bump?+
A swing high is a local peak with at least one clean lower candle on each side. The fewer and cleaner the swings, the more reliable your structure read — most traders mark only the obvious ones.
Which timeframe should I read structure on?+
Intraday SMC reads structure on the 15m for bias and the 1m/5m for confirmation. The daily and weekly set the backdrop but the checklist lives on the lower timeframes.
