What is Break of Structure?

A break of structure is a price move through a previously important swing high or swing low that changes the observed sequence of market structure.

Break of Structure matters because it gives analysts a consistent way to discuss price-structure interpretation. Market-structure terms describe how successive highs, lows, ranges and breaks relate to one another without requiring a separate indicator.

How to read Break of Structure

Read Break of Structure together with trend, timeframe, volatility and market context. Its main role is price-structure interpretation, not replacing the underlying price series.

What Break of Structure does not tell you

The key distinction is whether the move is sustained beyond the prior boundary rather than merely touching or briefly crossing it. Parameter choices, timeframe and data quality can materially change the result.

Use in bonds, rates and macro markets

A yield breakout and a bond-price breakout have opposite directional implications for rates, so the charted variable must always be identified.

BondStats interpretation rule

Technical chart structures are context, not certainty. BondStats does not present a candlestick, drawing tool, indicator reading or chart pattern as a standalone investment recommendation. Where a concept depends on discretionary anchors or parameter choices, those choices should be made explicit.
