ATR Calculator — Volatility-Based Stop Loss & Position Sizing
Calculate Average True Range (ATR) to measure market volatility. Use ATR for setting stop losses and identifying volatility breakouts.
True Range Calculator (1-Period ATR)
💡 Why Use This ATR Calculator?
ATR is the professional's volatility ruler. It tells you how much an asset typically moves per period — critical for setting stop losses that aren't too tight (always triggered) or too wide (excessive risk). Used by the world's best trend followers including the Turtle Traders.
Pro Tip: Multiply ATR by 2-3 for stop placement in trending crypto markets; use 1-1.5× ATR for tighter range-bound conditions.
Frequently Asked Questions
How do I use ATR for stop losses in crypto trading?›
ATR-based stop = Entry − (ATR × multiplier) for longs. If Bitcoin's 14-day ATR is $2,000, a 2× ATR stop sits $4,000 below entry. This adjusts automatically to current volatility rather than using arbitrary percentages.
What ATR period works best for crypto trading?›
14-period ATR (Wilder's default) works well for swing trading on daily charts. For intraday crypto trading, 14-period ATR on 1H or 4H charts gives volatility-adjusted stop levels for the specific session.
