What this does
Automatically detects and draws a parallel price channel — ascending, descending, or flat — based on real swing pivots, rather than requiring you to draw trendlines by hand.
Methodology

Automatically detects and draws a parallel price channel — ascending, descending, or flat — based on real swing pivots, rather than requiring you to draw trendlines by hand.
Methodology
- Detects alternating swing highs/lows (zigzag pivots), then looks for a same-type → opposite-type → same-type sequence (e.g. low-high-low) to anchor a channel: the base trendline runs through the two same-type pivots, and a parallel line is offset to touch the pivot in between.
- Direction is color-coded from the base trendline's slope: green = ascending, orange = descending, aqua = flat/parallel.
- Once formed, the channel locks in — it won't wobble or refit on every new minor pivot, only when it's actually broken by a decisive close beyond either boundary.
- A built-in sanity check rejects channels whose width is unreasonably large relative to the instrument's recent ATR, so a single outlier wick can't distort the fit.
- Works on any timeframe — tested particularly on 1H/2H/4H for spotting corrective structures, and on Daily/Weekly for larger trend channels.
Settings
- Pivot Left/Right Bars — pivot sensitivity (lower = more, smaller pivots; higher = fewer, larger ones)
- Min Move % Between Pivots — filters out insignificant zigzag noise
- Min Bars Between Anchor Pivots — avoids forming a channel from two anchor points that are too close together
- Max Channel Width (x ATR) — the outlier-rejection sanity check described above
- Break Buffer % — how far price must close beyond the channel before it's considered broken
Alerts
Fires when price breaks the channel upward or downward.
