RSI Explained: Momentum and Limits
Read RSI as bounded recent momentum rather than an automatic reversal command.
Key takeaways
- Specify calculation details.
- Treat thresholds as context.
- Test divergences without hindsight.
RSI Explained: Momentum and Limits: the decision context
RSI compares smoothed upward and downward changes on a zero-to-100 scale. Match period, smoothing, initialization, input, and warmup across implementations.
High or low readings describe lookback momentum but do not establish imminent reversal. Review every qualifying observation, including continuations.
What evidence deserves attention
Thresholds such as 70 and 30 are conventions whose behavior changes by regime and period. Test parameter sensitivity prospectively.
A repeatable review workflow
Using completed closes, calculate average gains and losses over the declared lookback, derive relative strength, and transform it to the 0-100 RSI scale. Inspect one rising market where RSI remains above 70 for several bars to test whether an immediate reversal interpretation would have failed.
Limits, failure modes, and risk
Divergence rules require pivot definitions that are often known only later. Delay signals until pivots are identifiable and count failed cases.
Initialization method, zero-loss handling, candle source, and smoothing convention can make platforms disagree. Threshold crossings are not probabilities, divergence pivots may be known late, and strong trends can keep RSI extreme while price continues moving.
