Volatility Regime Indicators: VTR & VRT

BigDipper includes two volatility regime indicators to help you answer a critical question before making a trade:
“Is the current market environment suitable for the strategy I’m about to use?”
These tools do not predict direction or guarantee profit. Their purpose is to help you avoid trading in unfavorable conditions and align the right strategy to the right environment.

​
VTR vs VRT Overview

Think of it as two questions:
  • VTR: What has volatility been doing lately?
  • VRT: What kind of risk environment am I trading in right now?
Both indicators use only price movement over the last ~3 months.

​
VTR — Volatility Trend Regime

What does VTR tell you? VTR measures whether recent price volatility is increasing, decreasing, or stable compared to normal. It answers:
“Is this a calm market where option selling usually works, or is volatility waking up?”

​
VTR Outputs

​
VTR Regime: One of Three States

​
VTR Ratio

Numeric comparison of short-term vs. longer-term volatility:
  • < 1.0 — Volatility is compressing
  • ≈ 1.0 — Volatility is stable
  • > 1.0 — Volatility is expanding
Note: You don’t need to trade based on this value — it supports the regime label.

​
VTR Score: 0–100

Higher score = calmer environment.

​
How to Use VTR

Use VTR as a strategy filter:
  • ✅ High VTR score — Short premium is structurally safer
  • ⚠️ Low VTR score — Risk for premium sellers rises
  • ❌ Expansion regime — Avoid aggressive theta trades
VTR does not tell you direction — it just says whether volatility conditions support your strategy.

​
VRT — Volatility Risk Regime

What does VRT tell you? VRT describes the market’s current risk character, not just volatility:
  • Market shocks
  • Instability
  • Tight squeezes
  • Trending vs. ranging behavior
It answers:
“Is this a stable environment, or is risk elevated even if price seems calm?”

​
VRT Regimes

​
VRT Bias (Action Hint)

Each regime gives a bias to guide risk posture: Tip: This is not a trade signal — it guides your risk posture.

​
VRT Score (0–1)

Confidence in current regime:
  • 0.8–1.0: Clear regime
  • 0.4–0.8: Mixed conditions
  • < 0.4: Unstable/unclear
Lower confidence: Trade less or reduce size.

​
How VTR and VRT Work Together

  • VTR explains volatility conditions
  • VRT explains risk conditions
You need both for optimal trading context.

​
How BigDipper Uses VTR & VRT

They are used to:
  • Cap or scale trade scores
  • Flag dangerous environments
  • Encourage less, not more, trading
  • Help match strategies to context
Think of them as guardrails, not predictions.

​
How to Use VTR & VRT in Your Trading

Follow these practical steps to leverage the VTR and VRT indicators and keep your trading aligned with current volatility and risk conditions:

​
Step 1: Check VTR First (Volatility Trend Regime)

  • Look at the vtr_ratio.
    Example: vtr_ratio = 0.80
    Interpretation: Short-term realized volatility is lower than long-term realized volatility.
    👉 This signals volatility is compressing, not expanding.
  • What it means:
    Compressing volatility regimes typically favor short-premium or income-oriented strategies.
  • Check the vtr_regime.
    Example: vtr_regime = "Stable"
    Interpretation: The market isn’t actively expanding or contracting in volatility—neutral for most strategies.
  • Review the vtr_score.
    Example: vtr_score_0_100 = 100
    Interpretation: Very calm; lowest perceived volatility risk.
    👉 “Recent movement is quieter than usual.”
Summary:
If VTR is calm/compressing with a high score, it’s a backdrop where short premium trades generally thrive.

​
Step 2: Scan the ATR Ratio (Range Stress Assessment)

  • Check the atr_ratio.
    Example: atr_ratio = 1.13
    Interpretation: Short-term trading ranges are expanding compared to the long term, even if closes are staying calm.
  • What it means:
    👉 Intraday volatility is picking up—occasional sharp moves can happen.
    It’s a caution flag: not panic, but reason to pay close attention.
  • Trading thought:
    “Closes are tame, but price action is becoming choppier under the surface.”

​
Step 3: Evaluate VRT (Risk Overlay & Shock Detector)

  • Look at the vrt_regime.
    Example: vrt_regime = "shock"
    Interpretation: The market environment is under stress (even if overall volatility is calm).
  • Does it clash with VTR?
    No—VRT gives extra context. For example, even in calm conditions, stress can build up beneath the surface (e.g., before news or during macro events).
  • When does this happen?
    • Before major catalysts or announcements
    • During transitionary periods
    • When ranges widen but there’s uncertain direction
  • Check the vrt_bias.
    Example: vrt_bias = "avoid/hedge"
    Guidance: Don’t aggressively sell naked premium. If you do trade, hedge carefully or reduce position size.
  • Review the vrt_score.
    Example: vrt_score ≈ 0.48
    Interpretation: Confidence is mid-to-low. This signals market instability—not full-blown chaos, but not safe either.

​
Putting It All Together

  1. Start with VTR to gauge underlying volatility trends—calm, stable, or expanding.
  2. Cross-check ATR ratio for sudden range expansion—a heads-up that things may be getting choppier intraday.
  3. Use VRT to overlay the risk environment—detecting hidden risks or market stress even if VTR says things are calm.
Final Guidance:
If VTR says “calm” but VRT is flashing “shock,” play defense: trade smaller or hedge, and never force a trade just because volatility is low.
Use these steps before every major trading decision—think of VTR and VRT as your “market weather report” for volatility and risk!

​
What VTR & VRT Do Not Do

They do not:
  • Predict price direction
  • Guarantee profit
  • Detect “smart money”
  • Replace risk management
Their sole purpose: Help you avoid mismatched strategies.

​
Summary

VTR tells you how volatility is changing.
VRT tells you how risky the market feels.
**Together, they help you trade only when conditions make sense.
