Math by Thomas Swing Range

Math by Thomas Swing Range is a simple yet powerful tool designed to visually highlight key swing levels in the market based on a user-defined lookback period. It identifies the highest high, lowest low, and calculates the midpoint between them — creating a clear range for swing trading strategies.

These levels can help traders:

Spot potential support and resistance zones

Analyze price rejection near range boundaries

Frame mean-reversion or breakout setups

The indicator continuously updates and extends these lines into the future, making it easier to plan and manage trades with visual clarity.

🛠️ How to Use
Add to Chart:

Apply the indicator on any timeframe and asset (works best on higher timeframes like 1H, 4H, or Daily).

Configure Parameters:

Lookback Period: Number of candles used to detect the highest high and lowest low. Default is 20.

Extend Lines by N Bars: Number of future bars the levels should be projected to the right.

Interpret Lines:

🔴 Red Line: Swing High (Resistance)

🟢 Green Line: Swing Low (Support)

🔵 Blue Line: Midpoint (Mean level — useful for equilibrium-based strategies)

Trade Ideas:

Bounce trades from swing high/low zones.

Breakout confirmation if price closes strongly outside the range.

Reversion trades if price moves toward the midpoint after extreme moves.
