 Each profile has its own confirm bars, ATR buffer, smoothing, ADX length/min, CHOP length/max, retest window/tolerance, min body fraction, and trend EMA. When profiles are OFF, the single global set of inputs is used.
 
+#### How to use profiles
+1) In the indicator Inputs, enable "Use per-timeframe profiles".
+2) Change the chart timeframe; the active profile is selected automatically:
+  - Intraday: under 60 minutes (e.g., 1, 3, 5, 15, 30, 45).
+  - 1–4h: from 60 to 240 minutes inclusive (1h, 2h, 3h, 4h).
+  - 1D+: daily and above (1D, 2D, 1W, 1M).
+3) Tune the controls in that profile group; they don’t affect the other profiles.
+4) Optional: Save as default or save an Indicator Template in TradingView to reuse your setup.
+5) Turn profiles OFF to revert to one global set of inputs across all timeframes.
+
+Tips
+- Global toggles like "Use ADX/DMI filter", "Use higher timeframe confirmation", "Use EMA trend filter", etc., apply to all profiles. The numeric thresholds/lengths inside each profile are per-profile.
+- For consistent behavior across TFs, start by scaling ATR Period with timeframe and then adjust Confirm bars and Buffer (×ATR) per profile.
+- Triangles, labels, and alerts follow the same gating and will only appear when all enabled filters pass.

 Use these as starting points and adjust per symbol/volatility. Values are for Heikin Ashi unless noted.
