Descriptive, not a guaranteed forecast

What is Relative Strength Index?

The Relative Strength Index is a bounded momentum oscillator that compares the magnitude of recent gains with recent losses, conventionally on a 0–100 scale.

Relative Strength Index matters because it gives analysts a consistent way to discuss momentum and oscillator analysis. Oscillators translate recent price behavior into bounded or comparative measures that can help identify acceleration, deceleration or stretched conditions.

How to read Relative Strength Index

Read Relative Strength Index together with trend, timeframe, volatility and market context. Its main role is momentum and oscillator analysis, not replacing the underlying price series.

What Relative Strength Index 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

They should be interpreted with the underlying instrument, liquidity and macro regime in mind rather than used as isolated bond-market forecasts.

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.
