Range Projection
Weekly Range Projection Calculator
Enter your daily ATR and current price to project an expected weekly trading range. The projection uses the standard square-root-of-time volatility scaling rule (weekly range ≈ daily ATR × √5, for 5 trading days), the same math used to scale daily volatility into longer horizons.

Educational tool only, not financial advice. Square-root-of-time scaling assumes volatility behaves like a random walk and is an approximation, not a guarantee of the week's actual range. Always confirm with your own strategy and risk management rules.
