Transient Zones v1.1 ‒ Indikator av Jurij

transient recurrent zones pricechannel volatility

Simple indicator to visualize Transient Zones (TZ) and Potential Transient Zones (PTZ).
The last 3 numbers in the header represent: probability of true TZ (black), probability of PTZ (navy) and probability of PTZ resolving (gray).
Original ForexFactory thread by EURUSDD

Version 1.1:
- Added TZ/PTZ occurrence probability thanks to SPYderCrusher

Todo:
- Mid bar transient zones detection
- Draw rectangles for zones (once rectangle drawing gets implemented in pine script) or use dot/circle lines
- Mark forming PTZs more clearly

Previous version 1.0:
