The Rolling Window setting on the HIRO chart controls the lookback period used to calculate the HIRO indicator — the same concept as an SMA (Simple Moving Average) applied to a price chart.

How it works

HIRO measures the real-time delta notional hedging pressure from options flow. The rolling window sums those values over a moving time window, smoothing out noise. A shorter window is more reactive to recent flow; a longer window smooths across a wider time range.

Available windows

• 1 min — most reactive, best for fast 0DTE scalping
• 5 min — standard short-term view
• 10 min — moderate smoothing
• 30 min — half-hour trend view
• 1 hour — intraday trend
• 4 hour — broader session-level view
• 1 day — full-day cumulative, useful for multi-day context

Which window to use

Choose the window that matches your trading timeframe — just as you would when selecting an SMA period on a price chart. Short-term traders typically use 1–5 min; swing or position traders may prefer 1h or 4h to filter out intraday noise.
