Build a VRP Dashboard with Python: Volatility Risk Premium Monitor in One API Call

The volatility risk premium is the difference between what options markets price in and what actually happens. Implied volatility is systematically higher than realized volatility because option buyers overpay for protection. This premium is the foundation of every premium-selling strategy.

Building a VRP dashboard from scratch requires sourcing chains, computing ATM IV, calculating realized vol across multiple windows, fitting a term structure, decomposing put vs call premiums, conditioning on dealer positioning, and scoring strategy suitability. That’s 3–6 months of engineering.

One API call replaces all of it.

What You Get

GET /v1/vrp/{symbol} returns the full VRP picture in a single JSON response: VRP spreads across 5d/10d/20d/30d windows with z-score and percentile, directional decomposition (put-side vs call-side premium), term structure by DTE bucket, gamma-conditioned regime analysis with a harvest score (0-1), strategy suitability scores for five structures (short straddle, strangle, iron condor, calendar, jade lizard), macro context (VIX, term slope, yields), and risk flags with warnings.

No manual IV computation. No realized vol calculation. No regime detection logic. Pre-computed and updated throughout the trading day.

Quick Start

from flashalpha import FlashAlpha

fa = FlashAlpha("YOUR_KEY")
vrp = fa.vrp("SPY")

print(f"ATM IV:        {vrp['vrp']['atm_iv']:.1f}%")
print(f"20d RV:        {vrp['vrp']['rv_20d']:.1f}%")
print(f"VRP spread:    {vrp['vrp']['vrp_20d']:.1f}%")
print(f"Z-score:       {vrp['vrp']['z_score']:.2f}")
print(f"Percentile:    {vrp['vrp']['percentile']:.0f}th")
print(f"Harvest score: {vrp['net_harvest_score']:.2f}")

The Dashboard Panels

The VRP gauge. The z-score tells you how many standard deviations the current VRP is from its 252-day mean. Above 1.5 means premium is in the top 7% of historical observations (rich). Below -0.5 means compressed (thin). Display this as the headline number with a traffic-light color scheme.

Multi-window comparison. The response includes realized vol at 5d, 10d, 20d, and 30d alongside VRP for each window. If VRP is rich at 5d but thin at 30d, the premium is driven by recent calm rather than structural richness. Show all four windows so traders can assess consistency.

Directional decomposition. Most VRP analysis treats the premium as symmetric. It isn’t. The directional object splits VRP into put-side and call-side using 25-delta wing IVs. When put-side VRP is 5% and call-side is 1%, selling an iron condor is wrong because the premium is concentrated on one side. This is what separates a useful VRP dashboard from a basic IV-vs-RV chart.

Term structure. VRP by DTE bucket (7d, 14d, 30d) shows which expiration has the richest premium per unit of time. Short-dated options typically have the highest VRP, but this reverses around events. Visualize as a bar chart.

Strategy scores. Five premium-selling structures scored 0–100. Iron condor scores high when VRP is elevated and balanced, gamma is positive, and VIX is in contango. Jade lizard scores high when put-side VRP is disproportionately rich. Calendar spreads score high when the term VRP curve is steep. The API does the scoring. Your dashboard just renders it.

The harvest score. This is the most important number. It combines VRP richness with the gamma regime into a single 0–1 composite. Elevated VRP in a negative gamma environment is a trap. The premium is rich because the risk is real. The harvest score catches this.

TSLA might show a z-score of 2.14 (93rd percentile) but a harvest score of only 0.52 because dealers are short gamma. SPY might show a lower z-score of 1.42 but a harvest score of 0.78 because dealers are long gamma and pinning price. Your dashboard should surface this distinction. Raw VRP richness alone is not a trade signal.

Risk flags. The warnings array flags conditions that make premium selling dangerous: negative gamma, FOMC, earnings, low liquidity. Display prominently. They override any positive VRP signal.

Multi-Symbol Scanner

fa = FlashAlpha("YOUR_KEY")
universe = ["SPY", "QQQ", "IWM", "TSLA", "NVDA", "AAPL", "AMZN", "META"]

results = []
for sym in universe:
    try:
        v = fa.vrp(sym)
        results.append({
            'symbol': sym,
            'z_score': v['vrp']['z_score'],
            'harvest_score': v['net_harvest_score'],
            'best_strategy': max(v['strategy_scores'], key=lambda k: v['strategy_scores'][k] or 0),
            'warnings': v['warnings']
        })
    except Exception as e:
        print(f"Skipping {sym}: {e}")

results.sort(key=lambda r: r['harvest_score'], reverse=True)

for r in results:
    warn = " ⚠" if r['warnings'] else ""
    print(f"{r['symbol']:>5}  harvest={r['harvest_score']:.2f}  z={r['z_score']:+.2f}  {r['best_strategy']}{warn}")

Sort by harvest score, not z-score. The harvest score already factors in the gamma regime.

Why Not Compute VRP Yourself?

You can. It requires: options chain data ($200–2,500/mo), ATM IV calculation with skew handling, realized vol across four windows, rolling z-score and percentile (252-day lookback), directional decomposition with 25-delta wing extraction, term structure fitting, gamma regime conditioning (itself a major project), strategy scoring model, and infrastructure to run intraday. That’s 3–6 months before you display a single number.
