Swing High/Low Lines (Break Stop)

Swing High/Low Lines (with alerts) – Strategy Description

This indicator automatically identifies market structure using swing highs and swing lows, then plots horizontal levels that extend forward until price breaks them. It is designed to track liquidity levels, highlight potential breakout points, and provide clean, event-based alerts.

Core Functionality
Detects swing highs and swing lows using a configurable strength setting
Plots each swing as a horizontal line starting at the pivot point
Lines extend forward in real time until price interacts with them
Once a level is broken, the line stops extending and is removed from tracking
Swing Detection
Uses ta.pivothigh and ta.pivotlow
The strength input defines how many candles are required on each side of a pivot
Higher strength = fewer, more significant levels
Lower strength = more frequent, sensitive levels
Line Behavior
Each swing level is drawn as an independent horizontal line
Lines extend right automatically as long as they remain unbroken
When price breaks a level:
The line is cut off at the break point
It is removed from active tracking
Prevents clutter by only keeping valid, untested levels active
Break Logic

Configurable via “Break on Wick” option:

Enabled (default):
A level is considered broken when price wicks through it
Disabled:
A level is only broken when price closes beyond it

This allows adaptation for:

Aggressive (wick-based liquidity grabs)
Conservative (confirmed close-based breaks)

1. Swing Creation Alerts

2. Break Alerts
