Index of highest value over a specified period (MAXINDEX)

Summary

Returns the index of the highest input value within a rolling window of optInTimePeriod bars. Same as MAX but outputs the location instead of the value.

Formula

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

Notes

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

Inputs

inReal — Input series to scan

Outputs

outInteger — Absolute index (into inReal) of the highest value in each window

Parameters

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