Connors RSI

Install and import

bash

npm install fintech-algorithms

import { connors_rsi } from "fintech-algorithms/technical-indicators/momentum/connors-rsi";

Signature

connors_rsi(close, pp, sp, rp)

The average of three components: RSI of price, RSI of the up/down streak length, and the percentile rank of the latest return. Designed for short-horizon mean reversion rather than trend.

Parameters

Name	Type	Notes
`close`	`number[]`	Per-bar closing prices, chronological.
`pp`	`number`	RSI period applied to price. min: 1 · integer: true
`sp`	`number`	RSI period applied to the streak-length series. min: 1 · integer: true
`rp`	`number`	Lookback for the percentile rank of the most recent return. min: 1 · integer: true

Returns

Record<string, (number | null)[]> · length same-as-input

Parallel series: price_rsi, streak, streak_rsi, percent_rank and connors_rsi.

Warm-up

The first the longest of the three components positions are null.

Errors

When any period is < 1 or is not an integer — throws RangeError

Complexity: time O(n × rp), space O(n).

Worked example

executed Captured by running this function on the input its own test provides. Real output of real code — but not asserted against a published figure.
