AutoTrendline Pro

AutoTrendline Pro automatically detects swing pivots and draws the most valid trendlines directly on your chart. Resistance lines appear as dotted lines and support lines as solid lines, both strictly validated against price action and removed immediately on a breakout, exactly like a professional chartist would draw them by hand. The replay-based algorithm builds every line from confirmed pivots only, so nothing repaints after the fact. You can control the left and right bars for pivot confirmation, the maximum number of active lines per type, and the colors of resistance and support lines to match your trading style.

Key features:

• Automatic pivot high and pivot low detection
• Strict no-intersection validation between pivot points
• Dotted resistance and solid support, extended to the right
• Breakout cleanup removes broken lines instantly
• Configurable max active lines and lookback pivots
• Smart redraw only when the line set changes, no chart flicker

Settings: Left Bars, Right Bars, Lookback Pivot, Max Active Lines, High and Low Colors.

Compatibility: any symbol and timeframe with enough history for pivot confirmation. Install from the Navigator panel as a standard custom indicator.
