Swing Levels is a technical indicator that automatically identifies key support and resistance levels on trading charts by detecting "swings" or pivot points—significant highs and lows. It analyzes a specified number of bars to the left and right of each candle to determine swing highs and lows, then draws lines or rectangular zones representing these levels. These levels serve as important references for price action analysis and trading decisions.

Key features include:
- Identification of recent swing highs and lows, which often act as future support or resistance.
- Visualization of market structure by highlighting patterns of higher highs and lows (bullish) or lower highs and lows (bearish), aiding trend recognition and reversal detection.
- A decision-making tool for traders to set entry points, stop-losses, and take-profit zones based on dynamic support and resistance.

Swing highs indicate potential resistance zones where price may reject or break out, while swing lows indicate potential support zones where price may bounce or break down. This indicator supports analysis across various markets and timeframes by providing clear visual cues of market turning points.
