Heikin-Ashi Bar Color Change Alert

The Heikin-Ashi Bar Color Change Alert indicator is a visualization and notification tool designed to track Heikin-Ashi candle transitions while maintaining a standard candlestick chart for price action analysis.

Usage

This script is designed to be applied to a standard candlestick chart rather than a Heikin-Ashi chart. It calculates Heikin-Ashi values in the background and highlights the current sentiment through visual cues:

• Background Color: The chart background changes color based on the calculated Heikin-Ashi candle state. A green background indicates a bullish Heikin-Ashi bar, while a red background indicates a bearish one.
• Arrows: Green up-arrows appear below the bar when the Heikin-Ashi color shifts from red to green. Red down-arrows appear above the bar when the color shifts from green to red.
• Alerts: Users can set up alerts to be notified immediately when a color change occurs, helping to identify potential trend reversals or momentum shifts.

Details

Heikin-Ashi (HA) candles are a derived candlestick type that aims to filter market noise by averaging price data. The script implements the standard HA OHLC calculations:

• HA-Close: Average of the actual Open, High, Low, and Close.
• HA-Open: Average of the previous HA-Open and previous HA-Close.
• HA-High: Maximum of the actual High, HA-Open, or HA-Close.
• HA-Low: Minimum of the actual Low, HA-Open, or HA-Close.

By monitoring the relationship between the HA-Close and HA-Open, the script identifies transitions in market sentiment.

Settings

As this script is a lightweight utility focused on price action transitions, it utilizes default calculation variables:

• Turn Green Shape: Controls the visual representation of the bullish reversal arrow.
• Turn Red Shape: Controls the visual representation of the bearish reversal arrow.
• Alert Conditions: Users can select "ha_green" or "ha_red" within the TradingView alert menu to trigger notifications on specific color changes.
