🎁 <174> 25_0825 ATR Pips — Zero-Centered BB2

ATR (Average True Range) is a volatility indicator that measures how much price typically moves per period—not direction, just magnitude.

Calculation:
True Range (TR) = max( high–low, |high–prev close|, |low–prev close| ).
ATR = a moving average (Wilder’s smoothing by default) of TR over N periods (commonly 14).

What it tells you: Bigger ATR ⇒ higher volatility; smaller ATR ⇒ quieter market.

Common uses:
• Position sizing (risk per trade)
• Volatility-based stops/targets (e.g., stop = entry − 1.5×ATR)
• Breakout filters and trailing stops (Chandelier Exit, Supertrend).

Notes: ATR is in price units; to compare across assets or time, use ATR% = ATR / price. It spikes on gaps and doesn’t predict direction.
