HUY - Williams Structure (MTF)

Description:
This indicator plots the “Williams Structure” as an MTF (multi-timeframe) overlay directly on the chart. It marks confirmed structure highs and lows and can optionally display retrace lines as well as a swing connection (Low→High→Low→…).
In addition, it shows the current break streak (e.g., Long x2 / Short x1) to quickly identify consecutive breaks.
The structure timeframe is freely selectable.
An optional auto-scaling feature can be used if symbol feeds have different price scaling.
All visual elements (lines, colors, styles, labels, swing path) can be toggled on/off individually.

Notes:
No trading signals / no orders: structure visualization only.
Non-repainting in the sense of confirmation (pivots/states are updated only after confirmation).
For very long histories, a line limit can be set to save resources.
