ATR Calculator
Calculate Average True Range to measure volatility.
Compute ATR deterministically from provided true-range observations to estimate average movement range.
Results
Average true range
1.9400
ATR from 5 true-range observations is 1.9400.
- TR sum
- 9.7000
- Periods
- 5
- ATR
- 1.9400
Formula
ATR = Average of true range values
Example
- True range 1: 1.8
- True range 2: 2.1
- True range 3: 1.5
- True range 4: 2.4
- True range 5: 1.9
What does this mean?
- •Higher ATR indicates wider average range movement.
- •ATR is non-directional and focuses on movement magnitude.
- •ATR can be used for volatility-aware stops and sizing.
Quantify average range volatility
ATR helps set stop distance and volatility-adjusted expectations.
What is a atr?
Compute ATR deterministically from provided true-range observations to estimate average movement range. In practice, this means you can quantify atr using true range 1, true range 2, true range 3, true range 4, and true range 5 without relying on hidden assumptions or black-box scoring.
Primary input set for this calculator: True range 1, True range 2, True range 3, True range 4, True range 5.
How to calculate atr
- 1.Step 1: Enter true range 1 with the timeframe/context you want to evaluate.
- 2.Step 2: Enter true range 2 with the timeframe/context you want to evaluate.
- 3.Step 3: Enter true range 3 with the timeframe/context you want to evaluate.
- 4.Step 4: Enter true range 4 with the timeframe/context you want to evaluate.
- 5.Step 5: Enter true range 5 with the timeframe/context you want to evaluate.
- 6.Step 6: Apply formula ATR = Average of true range values.
- 7.Step 7: Interpret output together with risk, liquidity, and catalyst context.
Why this metric matters
This metric helps convert raw time-series data into consistent signals for momentum, mean-reversion, and volatility context.
Pair this calculator with catalyst context from headlines, filings, and options flow to avoid relying on isolated numbers.
When to use this calculator
- ✓Before opening a new position where atr impacts sizing or risk.
- ✓After a catalyst to quantify how much conditions changed versus your baseline.
- ✓When comparing setups across multiple tickers with one consistent formula.
- ✓During weekly review to keep decision-making tied to measurable inputs.
Common scenarios
Higher ATR indicates wider average range movement
Use this atr workflow to quantify this scenario with deterministic inputs.
ATR is non-directional and focuses on movement magnitude
Use this atr workflow to quantify this scenario with deterministic inputs.
ATR can be used for volatility-aware stops and sizing
Use this atr workflow to quantify this scenario with deterministic inputs.
Event reaction review
Recalculate atr immediately after earnings, filings, or macro headlines.
Interpretation tips
- •Re-run atr whenever key inputs change materially, not only when price moves.
- •Document assumptions so the same methodology can be repeated across watchlist names.
- •Use this metric as one layer in the decision stack, not as a standalone trade trigger.
Data caveats
- –Outputs are deterministic from your inputs; input quality determines output quality.
- –This page does not auto-adjust for broker fees, taxes, or slippage unless you include them in your assumptions.
- –Validate corporate action details, filing dates, and data freshness before acting on results.
FAQ
How does the atr calculator work?
ATR Calculator is deterministic and uses only your inputs (true range 1, true range 2, true range 3, true range 4, true range 5). Formula: ATR = Average of true range values.
What does this output tell me in practice?
Calculate Average True Range to measure volatility. Technical indicators are context tools, so combine them with trend, liquidity, and catalyst awareness.
Does the atr calculator use real-time market feeds?
No. This page does not auto-pull live data. You control all inputs and can rerun instantly as market conditions change.
Can I use this result directly for trading decisions?
Use it as a planning layer. Combine with position sizing, liquidity, and catalyst context before any execution.
