Relative Strength Index (RSI)
Created by J. Welles Wilder, the Relative Strength Index is an oscillator that measures strength of the winning/losing streak over
N lookback periods on a scale of 0 to 100, to depict overbought and oversold conditions.
// usage IEnumerable<RsiResult> results = quotes.GetRsi(lookbackPeriods);
int - Number of periods (
N) in the lookback period. Must be greater than 0. Default is 14.
Historical quotes requirements
You must have at least
N+100 periods of
quotes to cover the convergence periods. Since this uses a smoothing technique, we recommend you use at least
10×N data points prior to the intended usage date for better precision.
quotes is a collection of generic
TQuote historical price quotes. It should have a consistent frequency (day, hour, minute, etc). See the Guide for more information.
- This method returns a time series of all available indicator values for the
- It always returns the same number of elements as there are in the historical quotes.
- It does not return a single incremental indicator value.
- The first
N-1periods will have
nullvalues since there’s not enough data to calculate.
⚞ Convergence warning: The first
10×Nperiods will have decreasing magnitude, convergence-related precision errors that can be as high as ~5% deviation in indicator values for earlier periods.
DateTime - Date from evaluated
double - Relative Strength Index

This indicator may be generated from any chain-enabled indicator or method.
// example var results = quotes .Use(CandlePart.HL2) .GetRsi(..);
Results can be further processed on
Rsi with additional chain-enabled indicators.
// example var results = quotes .GetRsi(..) .GetSlope(..);
