Lowest and highest values over a specified period (MINMAX)

Summary

Returns both the lowest and highest values of the input over a rolling window of the last optInTimePeriod bars. An overlap-study companion to MIN and MAX that computes both extrema in one pass.

Formula

outMin[i] = min(inReal[i-optInTimePeriod+1 .. i])
outMax[i] = max(inReal[i-optInTimePeriod+1 .. i])

Inputs

inReal — Values scanned for the window min and max

Outputs

outMin — Lowest value in each rolling window
outMax — Highest value in each rolling window

Parameters

Parameter	Type	Default	Accepted values	Description
`optInTimePeriod`	integer	30	2–100000	Rolling window length

Properties

Numerical Stability: Start-Independent


✅ Overlap Input i
☐ Independent Y-Axis
☐ Candlestick
☐ Can Output NaN or ±Inf
☐ Identity at Period 1
