How exactly does the EDR indicator, which combines VIX9D and 20-day historical volatility, drive iron condor strike selection in the VixShield methodology?

At VixShield, we rely on the EDR Expected Daily Range indicator as the foundational tool for strike selection in our daily 1DTE SPX Iron Condor Command trades. Developed by Russell Clark in the SPX Mastery series, EDR blends short-term implied volatility from VIX9D with 20-day historical volatility using a proprietary formula: EDR equals VIX9D multiplied by 0.1 plus 20-day HV multiplied by 0.5, then scaled by a regime-based multiplier between 0.8 and 2.0. This produces a precise forecast of the SPX's likely daily price excursion, which we use to place our wings at levels that capture the targeted credit while maintaining defined risk. For example, with the current SPX close at 7138.80 and VIX at 17.95, a typical EDR reading around 1.16 percent might suggest an expected daily range of approximately 83 points. We then apply RSAi Rapid Skew AI to fine-tune the exact strikes, adjusting in $5 increments on the call or put side first until we achieve the precise premium for our chosen risk tier. The Conservative tier targets a $0.70 credit with an approximate 90 percent win rate, the Balanced tier aims for $1.15, and the Aggressive tier seeks $1.60, all placed after the 3:09 PM CST SPX close cascade with signals firing at 3:10 PM CST. This process ensures our iron condors are mathematically aligned with current market conditions rather than arbitrary probabilities. The EDR also feeds directly into our Temporal Theta Martingale recovery mechanics and VIX Risk Scaling rules. When EDR exceeds 0.94 percent or VIX rises above 16, we may forward-roll threatened positions to 1-7 DTE to capture vega expansion before rolling back on a VWAP pullback when EDR drops below that threshold. Our ALVH Adaptive Layered VIX Hedge provides additional protection across short, medium, and long timeframes in a 4/4/2 contract ratio, cutting drawdowns by 35-40 percent at an annual cost of only 1-2 percent of account value. Position sizing remains at a maximum of 10 percent of account balance per trade, and we follow a strict Set and Forget approach with no stop losses, relying instead on Theta Time Shift for zero-loss recovery. All trading involves substantial risk of loss and is not suitable for all investors. To master these mechanics, explore the full SPX Mastery book series and join our live sessions at VixShield.com.
