Index of lowest value over a specified period (MININDEX)

Summary

Returns the absolute index of the lowest value within a rolling window of the given period. Same scan as MIN but outputs the position of the minimum rather than its value.

Formula

outInteger[i] = index of min(inReal[i-optInTimePeriod+1 .. i])

Notes

When several bars in a window share the lowest value, the index of the most recent of them is returned.

Inputs

inReal — Series to scan for its minimum

Outputs

outInteger — Absolute index in inReal of the lowest value in each window

Parameters

Parameter	Type	Default	Accepted values	Description
`optInTimePeriod`	integer	30	2–100000	Window length over which the minimum is located
