Wedge and Flag Finder (Multi - zigzag)

Here is a small attempt to automatically identify wedges and flags.

Tradingview standard wedge checks for only 4 pivots. In this version, I have considered 5 pivots instead - which can help reduce noise as 4 pivots forming wedge can be quite common. In future, will also try to add more pivots in pattern recognition to make the signal more accurate.

If wedge comes with a tail, then it is marked as flag :)
Settings are quite simple and they are as shown below

Versionsinformation:

Few updates

• You can now select wedge based on 5 or 6 pivots (defined in settings)
  
• Theme based colouring option added in the settings. Now users can chose either dark or light theme (Refers to chart background theme).
  
• Option added in settings to hide zigzag lines and labels within wedge.
  
• Angle based logic are refined as well as the settings. Angle restrictions are by default not selected as they often can be unreliable.
