# Trendline Breakout Navigator Trendline Breakout Navigator is an indicator on [Vela](https://vela.luxalgo.com/chart), our next-generation charting platform, written in Pine Script®. Maintains three self-optimizing trendlines at once (long, medium, and short term), each born from swing points and refined against historical closes. Dots mark wick tests that pierced a line without a closing break, bar colors grade every close against all three slopes, and background flips flag breaks of your chosen line. For trend traders who want diagonal structure at three scales. - Indicator in the LuxAlgo Library, by LuxAlgo, published Apr 2, 2025. - Access: free. - Concepts: [Trendline](https://www.luxalgo.com/library/concept/trendline/) (primary), [Breakout](https://www.luxalgo.com/library/concept/breakout/) - Open on Vela: https://vela.luxalgo.com/chart?pineScriptCodeId=cmpwn6nnp009evhsgyc22esvi - Page: https://www.luxalgo.com/library/indicator/trendline-breakout-navigator/ **Trendline Breakout Navigator** keeps three [trendlines](https://www.luxalgo.com/library/concept/trendline/) alive at once: a solid long-term line for overall market direction, a dashed medium-term line for intermediate movement, and a dotted short-term line for immediate fluctuations. Each begins as a horizontal line at a swing point, connects once a new higher low or lower high forms, and then optimizes itself against the historical closes that pierced it. The result is diagonal structure at three scales, maintained without a single manual drawing. ## How to Trade the Trendline Breakout Navigator? - **Blue and orange dots**: a higher low or lower high pierced a bullish (blue) or bearish (orange) trendline without the close breaking it. Tested lines like these can precede continuations or reversals. - **Green background**: price broke above a bearish trendline, or a new higher high printed. - **Red background**: price fell below a bullish trendline, or a lower low appeared. - **Bar colors**: green and red hues deepen according to how the close stacks up against the long, medium, and short-term lines together, a three-layer trend read at a glance. HH/LL labels mark where fresh trendlines are born, and the Period setting can source everything from a higher timeframe, with trendlines spanning up to 5000 bars, so a lower-timeframe chart can trade against bigger structure. ## Trendline Breakout Navigator Settings - **Period**: "chart" for the current timeframe, or a higher timeframe for broader trend recognition. - **Swing Length**: set per trendline; longer values produce longer-term swing levels. - **Term**: choose whether the Long, Medium, or Short-term line drives HH/LL labels and background coloring. - **HH/LL Labeling, Background Coloring, Bar Coloring**: independent visual layers, plus color controls for lines and wick dots. ## Frequently Asked Questions ### What exactly do the dots tell me? They mark the precise point where price exceeded a trendline intrabar while the close held the line, a failed [breakout](https://www.luxalgo.com/library/concept/breakout/) attempt that forces the trendline to update. Repeated tests reveal where the market keeps probing the trend's defense. ### How is this different from Trendlines with Breaks? [Trendlines with Breaks](https://www.luxalgo.com/library/indicator/trendlines-with-breaks/) manages one pivot-anchored pair with configurable slope and flags each break; the Navigator maintains three term-graded lines and scores every close against all of them. One is a lean signal tool, the other a full trend map. ### What does the Trendline Breakout Navigator cost? Nothing. It is free on the LuxAlgo Library.
