Auto trend lines

Auto Trend Lines is an indicator that finds the support and resistance lines in the price action and draws them for you. Where the drawing tools let you mark up structure by hand, this reads the recent swing pivots, fits the strongest lines through them, and extends each one out to the right edge - so the levels the market is actually respecting are on the chart without you placing a single point.

Overview

Section titled “Overview”

The indicator scans the recent bars for swing pivots - the local highs and lows that stand out from their neighbours - and looks for structure in them two ways. It finds horizontal levels by clustering pivots that stack up near the same price (a level tested several times), and angled trendlines by connecting pivots into a sloped line that price never breaks through across its span (a resistance stays above the highs, a support below the lows). Both kinds are pooled per side, ranked by how many pivots they touch and how recent those touches are, and the strongest few drawn - so a repeatedly-tested flat level shows up rather than being passed over for a sloped line.

It is pure geometry over the bars on screen - no model, no forecast. The lines describe the structure that is already there; they don’t predict the next move.

How to use

Section titled “How to use”

  2. Read the lines as levels to watch. A solid segment runs through the touch points; a dashed projection carries the line forward to the current edge, where price is most likely to meet it.

  3. Check the touch tag. Each line is labelled R ·N or S ·N - the number is how many pivots it touches. More touches means a level the market has respected more often.

  4. Tune it from the indicator’s gear icon:

    • Lookback - how many recent bars feed the fit. Shorter reacts to the latest swings; longer favours the bigger, slower structure.
    • Lines / Side - how many lines to keep per side, 1 to 4. Lower keeps only the strongest support and resistance; raise it to surface more secondary levels.
    • Pivot Strength - how many bars on each side a swing must lead to count as a pivot. Higher means fewer, more significant pivots.
