Custom ZigZag Indicator

7월 27일

Overview

The Custom ZigZag Indicator is a technical analysis tool built in Pine Script (version 5) for TradingView. It overlays on price charts to visualize market trends by connecting significant swing highs and lows, filtering out minor price noise. This helps identify the overall market direction (uptrends or downtrends), potential reversal points, and key support/resistance levels. Unlike standard price lines, it "zigzags" only between meaningful pivots, making trends clearer.

Core Logic and How It Works

The script uses a state-machine approach to track market direction and pivots:

Initialization

Starts assuming an upward trend on the first bar.
sets initial high/low prices and bar indices based on the current bar's high/low.

Direction Tracking:

Upward Trend (direction = 1):

Monitors for new highs: If the current high exceeds the tracked high, update the high price and bar.

Checks for reversal: If the low drops below the high by the deviation percentage (e.g., high * (1 - 0.05) for 5%), it signals a downtrend reversal.

Draws a green line from the last pivot (low) to the new high.

If labels are enabled, adds a label: "HH" (Higher High if above previous high), "LH" (Lower High if below), or "H" (for the first one).

Updates the last high and switches to downward direction.

Downward Trend (direction = -1):

Monitors for new lows: If the current low is below the tracked low, update the low price and bar.

Checks for reversal: If the high rises above the low by the deviation percentage (e.g., low * (1 + 0.05)), it signals an uptrend reversal.

Draws a red line from the last pivot (high) to the new low.

If labels are enabled, adds a label: "LL" (Lower Low if below previous low), "HL" (Higher Low if above), or "L" (for the first one).
Updates the last low and switches to upward direction.

Overview

The Custom ZigZag Indicator is a technical analysis tool built in Pine Script (version 5) for TradingView. It overlays on price charts to visualize market trends by connecting significant swing highs and lows, filtering out minor price noise. This helps identify the overall market direction (uptrends or downtrends), potential reversal points, and key support/resistance levels. Unlike standard price lines, it "zigzags" only between meaningful pivots, making trends clearer.

The indicator is dynamic and can "repaint" (update past lines) as new price data arrives, which is common for ZigZag tools since they rely on future confirmation of pivots.
Key Inputs and Customization

Users can adjust settings via TradingView's indicator inputs:

Deviation (%): The core sensitivity parameter (default 5%). It determines how much price must reverse (as a percentage) to form a new pivot. Higher values ignore smaller fluctuations for a smoother, longer-term view; lower values capture more short-term swings.
Up Leg Color: Color for lines showing upward moves (default green).
Down Leg Color: Color for downward moves (default red).
Line Width: Thickness of the zigzag lines (default 2, minimum 1).
Line Style: Choose "Solid" (default), "Dashed", or "Dotted" for line appearance.
Show High/Low Labels: Toggle to display labels at pivots (default true).

These allow full customization of appearance without changing the code.
