Forex Market Structure — Understanding Price Behaviour
Market structure is the foundational language of price action analysis. Before examining momentum indicators, patterns, or volume behaviour, educational analysts begin with the raw structure of price itself — the sequence of highs and lows that define whether a market is trending, ranging, or transitioning between the two.
The Building Blocks: Swing Highs and Swing Lows
Every chart, regardless of timeframe, is composed of a sequence of swing highs (peaks) and swing lows (troughs). The relationship between successive swings defines the structural character of the market:
- **Bullish structure**: A series of Higher Highs (HH) and Higher Lows (HL). Each new swing high exceeds the prior one; each pullback finds support above the previous low. - **Bearish structure**: A series of Lower Lows (LL) and Lower Highs (LH). Each new swing low undercuts the prior one; each relief rally fails below the previous high. - **Ranging structure**: Swing highs and lows form within a defined horizontal range, with neither buyers nor sellers establishing sustained directional control.
Break of Structure (BOS)
A Break of Structure is commonly labeled when price closes beyond a selected prior swing point. Definitions vary; the label describes a historical chart event and does not confirm trend continuation.
A BOS label may distinguish a candle close from an intraday wick through a level. The selected convention is interpretive and does not establish that a move is genuine or will persist.
Change of Character (CHoCH)
A Change of Character is a label sometimes used for a structural break that moves against a selected prevailing trend. In a bullish sequence, an analyst may apply the label to a break below a Higher Low. It does not establish that momentum is exhausting or predict a reversal.
The terms BOS and CHoCH distinguish chart classifications in some frameworks. Subsequent price data can be reviewed retrospectively; neither term confirms continuation or determines whether a move will reverse.
Multi-Timeframe Structure Alignment
No timeframe exists in isolation. Educational market analysts typically read structure from the top down:
1. **Weekly / Daily**: Establish the dominant structural bias — is price in a macro bullish or bearish phase? 2. **4-Hour**: Compare intermediate structure with the selected higher-timeframe example; apparent alignment does not establish probability. 3. **1-Hour / 15-Minute**: Identify the near-term structure for timing context within the higher-timeframe directional bias.
When 4H and Daily labels align, the agreement can be recorded as a historical observation. Alignment does not predict continued price behavior.
Displacement and Imbalance
In some technical-analysis frameworks, rapid price movement is described as displacement and a gap between neighboring candles as an imbalance. These chart labels do not establish institutional activity or show whether two-sided participation was available.
Historical examples can be reviewed for later interaction with a marked imbalance. A revisit or directional continuation is not implied.
