- Start with one centerline and one clear band set before adding complexity.
Centerlines
The centerline defines what “value” means for the bands. Choose it based on your market and session, not because it looks best after the fact.
| Centerline family | Use case |
|---|---|
| VWAP, NY VWAP, London VWAP, Rolling VWAP | Session-aware value, especially useful for futures intraday work. |
| SMA, EMA, HMA, WMA, DEMA, TEMA | Classic moving-average value references with different smoothness and reaction speeds. |
| Nadaraya-Watson, Savitzky-Golay | Smoother references for traders who want less noise in the value line. |
Deviation methods
- Percentile: default mental model for relative stretch.
- MAD: robust when outliers distort normal bands.
- IQR: robust range reference for non-normal movement.
- StdDev: familiar statistical width for traders used to volatility bands.
Band levels
PDB Pro uses a three-band structure. The 75 band frames context, the 90 band frames meaningful stretch, and the 97 band marks extreme extension. Treat the bands as location and risk context, not automatic entries.
Best practice. Avoid stacking every centerline and method at once. A readable chart beats a “complete” chart you cannot act on.
Mean-reversion return alerts
Create alerts after your centerline, method, band levels, and session choices are saved. If you materially change the PDB configuration, recreate the alert so TradingView uses the current settings.
- Use alerts to know when price returns from extension toward value.
- Filter alert usage by session if you only trade specific hours.
- Test the alert text and frequency before depending on it.
Chart workflow
- Pick the centerline that matches the session value you care about.
- Select the deviation method that handles the current market behavior cleanly.
- Use 75/90/97 bands to classify normal, stretched, and extreme movement.
- Wait for your own confirmation rules before acting on a return-to-value idea.
Troubleshooting
- Bands too wide or too narrow: review lookback, method, and centerline choice.
- Too many touches: use a higher band, longer lookback, or a more robust method.
- Chart is unreadable: remove unused centerlines and reduce labels.
- Script missing: verify the TradingView username used for access.
