Darvas Box Theory

The Darvas Box Theory tool identifies price consolidation ranges and trend-continuation setups using Nicolas Darvas’ classic box theory enhanced with modern volatility filters and automated trade management. This script provides a structured framework for trading momentum expansion by validating breakouts through volume, trend alignment, and adaptive risk protocols.

Usage

The Usage section describes how the script can be used to identify tradable market structures. The indicator continuously scans for consolidation periods, defining a "Box" when price remains within a specific range for a user-defined number of bars.

• Breakout Identification: Traders can choose between "Close" (candle must close outside the box) or "Wick" (any price touch outside the box) confirmation. A green signal indicates a bullish breakout, while red markers indicate bearish breakdowns.
• Trend & Volume Filters: To improve signal quality, users can enable an EMA trend filter to ensure they only take long trades during bullish regimes. The volume filter requires the breakout bar to exceed a specific multiplier of the average volume, filtering out low-participation "fakeouts."
• Trade Management: When a breakout is validated, the tool tracks the "trade state." It can signal "Add" opportunities if price breaks into a new, higher box while a trade is active.
• Visual Interpretation: Forming boxes are highlighted in blue. Once a breakout occurs, the box turns green (bullish) or red (bearish). A real-time dashboard provides data on the current box height, volume ratio, and open R-multiple.

Details

The script implements a dynamic construction model where the box ceiling and floor are defined by the highest high and lowest low of the "Confirmation Bars" period.

• Volatility Adjustment: To ensure boxes represent meaningful consolidation, the system checks the box height against the Average True Range (ATR). If the range is too narrow (controlled by the "Minimum Box Height" setting), the box is considered noise and is not validated.
• Rising Box Logic: Following classic Darvas principles, an optional filter requires each new box ceiling to be higher than the previous one, ensuring the system only focuses on progressive bullish momentum.
• Automated Trailing: The script manages exits using three modes: the Box Floor, the Breached Ceiling, or an ATR-based trailing stop. If "Trail Stop to Higher Boxes" is enabled, the protection level automatically advances as new structural floors are established.

Settings

Darvas Engine

• Source: The price source used for calculations (default is Close).
• Box Confirmation Bars: The number of bars required to define a new consolidation range.
• Minimum Box Height (ATR): Filters out boxes that are too small relative to market volatility.
• Require Rising Boxes: When enabled, only identifies new boxes with a ceiling higher than the previous one.
• Breakout Method: Determines if a breakout is triggered by a candle close or a wick touch.
• Historical Boxes: The maximum number of boxes displayed on the chart.

Filters (Volume & Trend)

• Use Volume Confirmation: Requires breakout volume to be higher than average.
• Volume Multiplier: The sensitivity for volume validation (e.g., 1.5x average volume).
• Use Trend Filter: Filters long signals based on an EMA (e.g., 200 EMA).

Risk & Display

• Stop Mode: Selection between Box Floor, Breached Ceiling, or ATR-based trailing stops.
• Trail To Higher Boxes: Automatically moves the stop loss up as new boxes form.
• Show Status Table: Toggles the real-time information dashboard.
• Candle Color: Overlays price with a neutral color to highlight the Darvas Box structures.

FAQ

How does the indicator define a completed box? A box is validated once price remains within the high/low range for the specified "Confirmation Bars" and meets the minimum ATR height requirement. It remains "active" until price breaks out of the ceiling or floor.

Can this indicator be used for shorting? While the tool identifies bearish breakdowns (displayed as red boxes/markers), the "Trade State" engine and trailing stop logic are optimized for long-side momentum trading in alignment with the original Darvas Theory.
