What is Trendline?
Trendline is a chart annotation or measurement tool used to place a structured reference directly on a price or yield chart. The result depends on the selected anchors and is an analytical overlay rather than a new market observation.
Trendline matters because it gives analysts a consistent way to discuss manual chart annotation and measurement. Drawing tools turn visual observations into explicit levels, slopes, ranges or scenario boundaries.
How to read Trendline
Read Trendline together with trend, timeframe, volatility and market context. Its main role is manual chart annotation and measurement, not replacing the underlying price series.
What Trendline does not tell you
The term should be read as descriptive chart language rather than as a self-contained forecast. Parameter choices, timeframe and data quality can materially change the result.
Use in bonds, rates and macro markets
In rates markets they can be used on yields, spreads and futures, but a drawn level is an analytical annotation rather than an independently observed market variable.
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.
