Gann Swing Points

Indicator Logic

This is a GANN-style swing indicator that classifies bars based on their high/low structure relative to the previous bar.
I strongly encourage you to replay bars on Tradingview using this indicator to get a sense of how it creates pivot (or swing) points

Bar Classification:

Up-Bar (direction: 'up'): Higher High and Higher Low (HH/HL)

Down-Bar (direction: 'down'): Lower High and Lower Low (LH/LL)

Outside-Bar (generates 2 directions):

Green: 'down' then 'up'

Red: 'up' then 'down'

Inside-Bar: No direction generated (HL/LH)

Swing Line Logic

The swing line continues in the current direction until n opposite directions are detected.

n is the "n-direction" parameter (commonly set to 2, so 2 consecutive opposite direction is needed to turn the swing)

When n opposing directions occur, the swing turns, creating a pivot point

Inside bar is ignored, so e.g up-bar -> inside-bar -> up-bar generates "up", "up" direction

A top pivot is formed when the swing turns down

A bottom pivot is formed when it turns up

Note: This swing logic is inherently lagging — it only confirms tops/bottoms after the fact

This swing structure gives the system a clear and noise-resistant way to identify pivot points (swing-points)
