What it does
Relative Strength Comparison plots the ratio of the chart symbol's price to a comparison symbol (for example a stock divided by its index). A rising line means the chart symbol is outperforming the benchmark; a falling line means it is underperforming. This is relative strength in the ratio sense, not the RSI oscillator.

How traders use it
- Prefer longs in symbols whose ratio line is rising versus the index, and shorts or avoidance where it is falling; leaders tend to keep leading.
- A new high in the ratio before price makes a new high is bullish leadership; a ratio breakdown while price holds flat often precedes price weakness.
- Draw trendlines and support/resistance on the ratio itself; ratio breakouts frequently lead price breakouts.
- Use it for pair selection: within a sector, buy the strongest ratio and avoid or short the weakest.
- Combine with the benchmark's own trend: outperformance in a falling market may only mean 'falling less'.

Tips
- Use Add to favorites in the legend menu; starred studies surface at the top of the picker.
- Reference levels (where the study has them) are editable — tune them to the instrument you're trading.
- Hide the study from the legend eye instead of removing it when you only want it out of the way temporarily.
- This indicator accepts another symbol — leave it empty to use the chart's own symbol.
Watch out for
- A rising ratio does not guarantee rising price; the symbol can outperform simply by declining more slowly than the benchmark.
- The line's meaning depends entirely on the benchmark chosen; a mismatched or illiquid comparison symbol gives misleading readings.
