What strike selection process combines the Expected Daily Range (EDR) and RSAi for the 3:10 PM CST SPX Iron Condors?

At VixShield we rely on a precise two-stage strike selection process that fuses the Expected Daily Range indicator with our proprietary RSAi engine to generate daily 1DTE SPX Iron Condor signals at 3:10 PM CST. The process begins with EDR which blends short-term implied volatility from VIX9D and 20-day historical volatility to forecast the likely daily price excursion for SPX. With current SPX at 7138.80 and VIX at 17.95 the EDR typically projects a range of roughly 1.16 percent or about 83 points. This statistical envelope supplies the initial High Medium and Low strike recommendations that align with our three risk tiers Conservative targeting 0.70 credit Balanced at 1.15 credit and Aggressive at 1.60 credit. RSAi then takes over as the final optimizer. In the final minutes before the 3:10 PM CST signal RSAi scans real-time options skew implied volatility surface positioning relative to VWAP and short-term VIX momentum. It dynamically nudges the EDR-derived wings in five-dollar increments alternating call-side and put-side until the exact credit target is achieved within approximately 253 milliseconds. This ensures the placed condor matches what the market is actually willing to pay rather than a purely statistical guess. Because we trade exclusively 1DTE SPX Iron Condors the strikes are chosen to keep delta under 0.18 and gamma below 0.05 maximizing theta capture while remaining inside the projected range on approximately 82 to 90 percent of trading days depending on tier. The Conservative tier historically wins about 18 out of 20 days. Once placed the position follows our Set and Forget methodology with no stop losses relying instead on the Theta Time Shift recovery mechanism and our three-layer ALVH hedge which remains active across all VIX regimes to cut drawdowns by 35 to 40 percent at an annual cost of only 1 to 2 percent of account value. Position size never exceeds 10 percent of account balance. All trading involves substantial risk of loss and is not suitable for all investors.
