Definitions
In plain terms
Prior observations equal to the current return receive no partial or full lower-rank credit under this package.
Technical
The comparator, floating-point tolerance, window population, denominator, and missing values must be frozen.
Scope
Different midrank or less-than-or-equal conventions can produce different Connors RSI values.
Formula
Strict-lower percent rank = 100 * count(prior values < current) / NPR_t=100\frac{\#\{r_i<r_t\}}{N}| Symbol | Meaning | Unit |
|---|---|---|
r_i | prior reference return | percent |
r_t | current return | percent |
N | number of prior reference returns | observations |
Output unit: percent
Examples
- A governed lesson calculates or identifies Strict-Lower Rank only after its inputs, window, state, scale, and edge cases are declared.
Common misconceptions
- Different midrank or less-than-or-equal conventions can produce different Connors RSI values.

Supports: preferred label, short definition, technical definition, formula
Limits: The moving branch can change; exact parity requires a pinned revision and an explicit tie and ranking-window contract.
