Darvas box (with alerts)

The Darvas box (with alerts) indicator identifies consolidated price ranges based on the Darvas Box theory to highlight potential breakout opportunities. This tool automates the detection of price boxes and provides visual alerts when the price breaches the established boundaries, helping traders identify momentum shifts.

Usage

The Usage section describes how the script can be used to identify trend continuations or reversals. Traders typically look for the price to break above the top of a Darvas box as a bullish signal, or below the bottom of a box as a bearish signal.

For example, if the price is trending upward and forms a Darvas box, a breakout above the top boundary suggests the trend is resuming. Conversely, a break below the box might indicate a trend reversal or a deeper correction. This script utilizes the box.new() function to clearly visualize these ranges directly on the chart, changing color based on the price relation to the boundaries (green for bullish breakouts, red for bearish breakdowns).

Details

The indicator is based on the methodology developed by Nicolas Darvas. It calculates the boxes by identifying recent highs and lows over a specific lookback period. A box is formed when the price fails to make a new high for a set number of bars, establishing a "ceiling" and a "floor."

This specific implementation refines the logic to ensure boxes are drawn accurately using modern Pine Script drawing objects. It monitors for instances where the current high exceeds the highest high of the previous bars to reset the box formation process, ensuring the levels remain relevant to current market volatility.

Settings

• Box Length: Determines the number of bars used to calculate the highest highs and lowest lows for box formation. A higher value results in larger, more significant boxes, while a lower value makes the indicator more sensitive to short-term price fluctuations.
