Relative Strength Index
Measures the balance of recent gains and losses on a bounded scale.
Start with the input, not the story.
The speed and persistence of recent positive versus negative closes.
Plain-language formula
Platform implementations can differ in price input, smoothing, indexing and rounding. Record the exact settings and provider before comparing results.
Where it may help
Momentum regimes, range extremes and divergence studies.
Where it struggles
Strong trends, where an extreme reading can persist for much longer than expected.
Add a different measurement.
A complementary tool should answer a different question, such as volatility, regime or position risk. Test the base rule before testing the combination.
The shortcut to avoid
Selling at 70 or buying at 30 without trend, location or confirmation.
A testable next step
Compare fixed 70/30 thresholds with 60/40 regime rules and predefine exits.
