HH/LL Trendlines [twr]
Automatically detects swing structure (HH/HL/LH/LL) using pivot highs/lows, labels each swing point, and — the key feature — draws trendlines connecting same-type consecutive pivots: LH→LH on the high side, HL→HL on the low side. This visualizes the two "structure lines" traders watch for trend continuation and potential breaks.

Inputs summary
How it works
- Pivot detection & classification
- Uses ta.pivothigh()/ta.pivotlow() with a user-defined Swing Length (fractal-style, symmetric lookback/lookforward)
- Each new swing high is compared to the prior swing high: higher → labeled HH (bullish, green), lower → labeled LH (bearish, red)
- Each new swing low is compared to the prior swing low: lower → labeled LL (bearish, red), higher → labeled HL (bullish, green)
- First pivot on each side gets a neutral "x" label since there's nothing to compare against yet
Trendline logic
- Only connects pivots of the same classification — so a LH connects to the previous LH (skipping over any HH in between), and a HL connects to the previous HL. This produces clean descending-resistance / ascending-support structure lines rather than zigzagging between every pivot.
- Lines are capped per side (Max Trend Lines Shown) using an array-based pool with oldest-first trimming, so the chart doesn't get cluttered over time
Live projection
- If Project Lines Forward is enabled, each line's slope is recalculated every bar and extended to the current bar (getProjectedY()), so the structure line behaves like a live trend channel boundary rather than a static segment frozen at the two pivot points
- Optional Remove Line Once Price Crosses It will auto-delete a line when price closes (or wicks, depending on Cross Source) through the projected level — useful for treating the line as an invalidated trendline break
Inputs summary
- Structure: swing length, label toggle
- Trend Lines: enable high/low connections independently, line width/style, max lines per side
- Projection: forward extension toggle, cross-removal toggle, cross source (Close vs High/Low)
- Colors: bullish/bearish color customization
