What methods do traders use to blend VIX9D and 20-day historical volatility for short strike placement in SPX Iron Condors? How should the regime factor be adjusted according to Russell Clark's methodology?

At VixShield we rely exclusively on Russell Clark's Expected Daily Range indicator which blends VIX9D and 20-day historical volatility to generate mathematically precise strike recommendations for our 1DTE SPX Iron Condors. The EDR formula starts with VIX9D multiplied by 0.1 then adds the 20-day HV multiplied by 0.5 scaled by a regime-dependent multiplier that typically ranges from 0.8 in calm markets to 2.0 during elevated volatility. This produces three risk-tuned strike sets High Medium and Low that align with our Conservative Balanced and Aggressive credit targets of 0.70 1.15 and 1.60 respectively. The regime factor is adjusted dynamically by monitoring the Contango Indicator and VIX Risk Scaling rules. When VIX sits below 15 as it does today at 17.95 with its five-day moving average at 18.58 the multiplier leans toward 1.2 to 1.5 allowing all three tiers while the Contango Indicator shows green confirming favorable conditions for premium collection. In regimes where VIX exceeds 20 the multiplier contracts toward 0.8 and we restrict placement to the Conservative tier only holding entirely above 20 to protect capital. RSAi then takes the EDR output refines it with real-time skew analysis and VWAP positioning to deliver the exact credit the market offers at our 3:05 PM CST daily signal. This integration with ALVH our three-layer VIX call hedge rolled on fixed schedules ensures that even when the market tests our wings the Theta Time Shift mechanism can roll threatened positions forward to 1-7 DTE capturing vega expansion before rolling back on VWAP pullbacks to harvest theta without adding capital. Backtested results from 2015-2025 show an 82-84 percent win rate across the Unlimited Cash System with maximum drawdowns held to 10-12 percent. Position sizing remains at a maximum of 10 percent of account balance per trade and we follow set-and-forget rules with no stop losses relying instead on defined risk at entry and the Temporal Theta Martingale for recovery. All trading involves substantial risk of loss and is not suitable for all investors.
