insidePitchfork

Draw a classic Pitchfork (Inside) using three anchors: a main pivot and two side points. It’s great for spotting trend paths, bounce zones, and where price might “walk” inside the three rails (upper, median, lower). Think of it as a guided channel with a centerline to keep you oriented.

Syntax

insidePitchfork(pivot, left, right, styles?)

Parameters

• pivot: The main anchor of the pitchfork. Build it with newPoint(time, price).

• left: The first side anchor. Also created with newPoint(time, price).

• right: The second side anchor. Same builder: newPoint(time, price).

• styles (optional) Visual options you can pass as an object:

  • linecolor: color of fork lines (e.g., color.aqua)

  • medianColor: color for the center (median) line

  • linewidth: thickness of lines

  • linestyle: solid, dashed, dotted

  • showLabel: show a small label if the tool supports it

  • textcolor: color of the label text

Return Value

• string — Unique drawing id so you can later update or delete the pitchfork.

Example

This script draws one inside pitchfork every 24 candles to keep the chart tidy. We pick three meaningful pivots: a main pivot (older swing), and two side points (more recent swings). Lots of comments are included for clarity.

//@version=1
init = () => {
    // Put drawings on the main price chart and inherit its format (price/percent)
    indicator({ onMainPanel: true, format: 'inherit' });
};

onTick = () => {
    // Every 24 candles, draw a new Inside Pitchfork
    if (index % 100

 === 0) {
        // 1) Choose the three anchors as time/price points.
        //    Use swing lows/highs so the fork lines feel natural to the trend.

        // Main pivot (the “handle”): 20 candles ago at its LOW
        const pivot = newPoint(time(20), low(20));

        // Left side point: 10 candles ago at its HIGH (helps define direction)
        const left  = newPoint(time(10), high(10));

        // Right side point: 8 candles ago at its LOW (sets the other side)
        const right = newPoint(time(8),  low(8));

        // 2) Draw the Inside Pitchfork:
        //    - linecolor: aqua to stand out
        //    - linewidth: 2 for good visibility
        //    - Optional: you can add medianColor or linestyle if you want
        insidePitchfork(
            pivot,
            left,
            right,
            { linecolor: color.aqua, linewidth: 2 }
        );
    }
};

Result

Tips

• Use obvious swing points for pivot, left, and right. The cleaner the anchors, the more meaningful the fork.

• Try mixing high/low combinations that reflect the current trend direction (e.g., low→high→low in an uptrend).

• If you want the fork to adjust over time without clutter, save the returned id once and call updateDrawingById(id, [pivot, left, right]) instead of creating new ones.

Warning

• If any of your points are missing time or price (for example, you passed NaN), nothing will be drawn.

• Extremely close anchors can produce near‑overlapping lines, making the fork hard to read.

• Drawing too many forks too often (like index % 1) will clutter the chart quickly.

Good Practice

• Keep a consistent color scheme for pitchfork tools (e.g., aqua for Inside Pitchforks) so users recognize them instantly.

• Space out creation (e.g., index % 24, index % 36) to avoid stacking many forks.

• Combine a pitchfork with a horizontalRay or trendLine to mark key reactions along the median or outer rails.
