Deep Signal VPIN – Parameters

This section describes each configurable parameter for the VPIN indicator and how it affects behavior, responsiveness, and visualization.


Overview

Deep Signal VPIN measures order flow toxicity by analyzing the imbalance between buying and selling volume within fixed-size volume buckets.

It produces a value between 0 and 1:

  • 0 → Balanced, low-risk market conditions
  • 1 → High imbalance, elevated risk / informed trading activity


VPIN helps traders identify when the market is becoming:

  • Efficient and stable
  • Unstable, aggressive, or dominated by informed participants



Here is the Properties dialog that contains the VPIN parameters.




Parameters

Bucket Volume Size

Default: 1000
Description:
Defines the total volume required to form a single VPIN bucket.

Instead of using time-based bars, VPIN aggregates trades until this volume threshold is reached.

Usage:

  • Smaller values (e.g., 500–1000):
    • More responsive
    • Better for scalping / fast markets
  • Larger values (e.g., 2000–5000):
    • Smoother signal
    • Better for trend and swing analysis


Lookback Buckets

Default: 20
Description:
Number of completed volume buckets used to calculate the VPIN value.

This determines how much historical imbalance is considered.

Usage:

  • Lower values (10–20):
    • Faster reaction to changes
    • More sensitive but noisier
  • Higher values (30–50):
    • Smoother, more stable signal
    • Slower to react


VPIN Moderate Level

Default: 0.5
Description:
Threshold that defines moderate imbalance / rising market risk.

When VPIN exceeds this level:

  • Market begins transitioning from balanced → imbalanced
  • Early warning of potential instability


VPIN High Level

Default: 0.7
Description:
Threshold that defines high imbalance / elevated toxicity.

When VPIN exceeds this level:

  • Strong indication of informed trading or aggressive order flow
  • Market conditions may become:
    • Volatile
    • Less predictable
    • Prone to sharp moves


Low VPIN Color

Default: DimGray
Description:
Color used when VPIN is below the Moderate Level.

Interpretation:

  • Balanced order flow
  • Lower risk environment
  • More stable price behavior


Moderate VPIN Color

Default: Gold
Description:
Color used when VPIN is between:

  • Moderate Level and High Level

Interpretation:

  • Increasing imbalance
  • Market transitioning into higher risk conditions
  • Traders should become more cautious


High VPIN Color

Default: Crimson
Description:
Color used when VPIN exceeds the High Level.

Interpretation:

  • Strong imbalance
  • Elevated probability of informed or aggressive trading
  • Increased likelihood of:
    • Sharp moves
    • Liquidity gaps
    • Stop runs


Visual Elements

VPIN Plot

Displayed as a histogram:

  • Values range from 0 to 1
  • Color-coded by risk level:
    • Gray → Low risk
    • Gold → Moderate risk
    • Red → High risk


Moderate Line

Horizontal reference line at the VPIN Moderate Level:

  • Indicates transition into rising imbalance


High Line

Horizontal reference line at the VPIN High Level:

  • Marks extreme imbalance conditions


Interpretation Guide

Low VPIN (< 0.5)

  • Balanced buying and selling
  • Efficient market conditions
  • Better for:
    • Trend continuation
    • Structured setups


Moderate VPIN (0.5 – 0.7)

  • Growing imbalance
  • Early signs of stress
  • Watch for:
    • Breakouts
    • Regime shifts


High VPIN (> 0.7)

  • Strong imbalance / informed activity
  • Market may become:
    • Unstable
    • Volatile
    • Reactive


Best Practices

Scalping

  • Use smaller Bucket Volume Size
  • Lower Lookback Buckets
  • Focus on rapid VPIN spikes


Intraday Trading

  • Moderate bucket size and lookback
  • Use VPIN as a risk filter
  • Avoid entering during extreme VPIN unless trading volatility


Swing Trading

  • Larger bucket sizes
  • Higher lookback values
  • Focus on sustained VPIN regimes rather than short-term spikes


Key Insight


VPIN answers a critical question:

👉 “Is the market currently being driven by balanced participation—or informed, aggressive flow?”

High VPIN environments often precede:

  • Breakouts
  • Liquidity shocks
  • Increased volatility









Futures, foreign currency and options trading contains substantial risk and is not for every investor. An investor could potentially lose all or more than the initial investment. Risk capital is money that can be lost without jeopardizing ones financial security or lifestyle. Only risk capital should be used for trading and only those with sufficient risk capital should consider trading. Past performance is not necessarily indicative of future results.
