Smart Money Volume [JoeyWave]
Smart Money Volume highlights statistically abnormal volume bars and quantifies real-time buy/sell pressure using two well-established methods from quantitative finance.
═══════════════════════════════
WHAT IT DOES
═══════════════════════════════
• Volume Panel — amber bars mark statistical outliers detected via Tukey's IQR method
• Pressure HUD (top-right) — shows current dominant side (BUY / SELL), pressure magnitude (%), and strength (WEAK / MODERATE / STRONG)
═══════════════════════════════
METHODOLOGY
═══════════════════════════════
1. Outlier Detection — Tukey's Interquartile Range
threshold = Q3 + k × (Q3 − Q1)
Default k = 2.0 ("extreme outlier" by Tukey's standard). This is robust to skewed volume distributions where mean/std-based methods fail.
2. Buy/Sell Classification — Bulk Volume Classification (BVC)
Based on Easley, López de Prado, O'Hara (2012). Each bar's volume is split into buy/sell proportions using the normalized log-return:
buy_fraction ≈ Φ(log_return / σ)
where Φ is the standard normal CDF, approximated with a logistic function.
3. Aggregated Pressure
Weighted buy and sell volumes are summed over the lookback window (default 20 bars). Pressure = buy_volume / total_volume.
═══════════════════════════════
HOW TO READ
═══════════════════════════════
• Amber bars → unusual volume activity worth investigating
• HUD BUY ▲ → buyers dominant; check % for conviction
• HUD SELL ▼ → sellers dominant
• STRONG ≥ 65% → high conviction
• MODERATE ≥ 55% → moderate
• WEAK < 55% → indecisive, near equilibrium
═══════════════════════════════
HOW TO USE
═══════════════════════════════
• Confluence tool — confirm breakouts, reversals, or trend continuation when an outlier aligns with your setup
• Pressure HUD as a regime filter — only take long setups when HUD shows BUY MODERATE+, shorts when SELL MODERATE+
• Look for divergences — price making new highs while pressure flips to SELL is a classic exhaustion signal
═══════════════════════════════
SETTINGS
═══════════════════════════════
• IQR Lookback — bars used for percentile calculation (default 50)
• IQR Multiplier — 1.5 = standard outlier, 2.0 = extreme (default)
• BVC Sigma Window — return volatility window (default 50)
• Pressure Lookback — bars aggregated for the HUD (default 20)
