VWAP Deviation Oscillator

The VWAP Deviation Oscillator indicator transforms VWAP context into a clean, tradeable oscillator that measures price distance from various VWAP anchors across multiple assets and sessions. It enables traders to identify polarity shifts, overbought/oversold conditions, and the strength of price extensions through a standardized visual framework.

Usage

The Usage section highlights how to interpret the oscillator for different trading styles:

• Trend Following: Traders can use the zero line to determine bias. Positive values indicate a bullish bias, while negative values indicate a bearish bias. Support or resistance at the +1 or +2 sigma tiers during pullbacks often signals trend continuation.
• Mean Reversion: By using the Z-Score mode, traders can identify statistical extremes at ±2 to ±3 sigma levels. When the price fails to progress beyond these bands and the oscillator rolls back toward zero, it may signal a mean reversion opportunity.
• Session Context: Use "Daily" or "Weekly" modes for intraday or swing trading context. "Rolling" modes are effective for assets without clear session boundaries or for maintaining a continuous anchor that adapts to liquidity shifts.

Details

The script measures the gap between the price and a selected VWAP anchor, expressing it in three distinct ways: Percent, Absolute price units, or a standardized Z-Score.

To ensure the signal remains relevant during changing market conditions, the tool includes volatility guards that compute mode-specific sigma thresholds. The visual encoding uses a 10-zone color palette to grade the magnitude of deviation, helping traders quickly distinguish between mild rotational movements and decisive institutional imbalances.

Settings

Calculation Settings

• VWAP Mode: Choose between fixed session resets (4 Hours, Daily, Weekly) or dynamic trailing windows (Rolling Bars or Days).
• Rolling Lookbacks: Defines the trailing bar count or day count for the rolling VWAP calculation.
• Use Close instead of HLC3: Switches the price reference from the typical average (HLC3) to the closing price.

Deviation Mode

• Deviation Mode: Selects the measurement lens (Percent, Absolute, or Z-Score).
• Z/Std Window: Sets the lookback period for calculating the mean and standard deviation specifically for the Z-Score mode.

Volatility Controls

• Percent/Absolute Volatility Lookback: Sets the window used to estimate sigma for the respective modes.
• Minimum Sigma Guard: Prevents the sigma thresholds from collapsing during extremely low volatility periods in Percent mode.

Visual Settings

• Plot Type: Toggle between a Histogram (best for impulse) or a Line (best for trend waves).
• Show Standard Deviations: Displays symmetric ±1, ±2, and ±3 sigma rails.
• Fill Line Oscillator/Opacity: Controls the background fill for the line plot.

FAQ

How do I use the different deviation modes?

Percent mode is best for comparing stretches across different price levels, Absolute is used when raw price units matter for risk, and Z-Score is ideal for standardized, scale-invariant research.

What do the different colors represent?

The colors represent the magnitude of deviation. Deeper greens/reds indicate price is significantly far from the VWAP (beyond 2 or 3 sigma), while lighter shades suggest price is rotating near "fair value."
