## Quantitative Attribution: Partial Derivative Formulas, Scaling Units & Tenor Surface Grid

Evaluating VANNA-CHARM-FLOWS across exact Black-Scholes-Merton analytical derivatives across 0DTE, 7DTE, 30DTE, and 90DTE requires reconciling primary data feeds from Cboe Options Institute against secondary clearing and market-microstructure indicators. At the current print of 6.5 hrs (Intraday Cash Decay Window) (Source: Cboe Options Institute, 2026-10-20), a 100-basis-point or 1-standard-deviation shift alters portfolio capital efficiency by 18.5 to 42.0 basis points across a standard $100,000,000 institutional notional book (Source: Cboe Options Institute Technical Methodology, 2026-10-18).

When cross-checked against OCC STANS 20-Minute Intraday Risk Snapshots & 0DTE Margin Add-On at 20 min (Intraday Monte Carlo Interval) (Source: The Options Clearing Corporation, 2026-10-20), desks isolating exact Black-Scholes-Merton analytical derivatives across 0DTE, 7DTE, 30DTE, and 90DTE capture a measurable structural spread while maintaining full alignment with Cboe Futures Exchange (CFE) guidelines ($1,000 Standard VX Point Multiplier, Source: Cboe Futures Exchange (CFE), 2026-10-18).
