How does the integration of EDR, RSAi, and VIX9D influence strike selection for daily 1DTE SPX Iron Condors?

At VixShield, we rely on a precise integration of EDR, RSAi, and VIX9D to select strikes for our daily 1DTE SPX Iron Condors. The process begins at 3:10 PM CST each market day, immediately following the 3:09 PM SPX close cascade. Russell Clark's SPX Mastery methodology uses EDR as the foundational Expected Daily Range indicator. Built on VIX9D implied volatility blended with 20-day historical volatility and a regime-adjusted multiplier, EDR currently projects a 1.16 percent daily range on an SPX close of 7138.80. This gives us objective outer-wing targets roughly 83 points away from spot under the prevailing VIX of 17.95. RSAi then refines those wings in real time. The Rapid Skew AI scans the live options skew surface, last-four-hour VIX momentum, and SPX position relative to VWAP. It adjusts the call or put side first in five-dollar increments until the exact credit target is reached: 0.70 for Conservative, 1.15 for Balanced, and 1.60 for Aggressive. VIX9D supplies the short-term implied volatility input that keeps EDR responsive; at present VIX9D contributes roughly 60 percent of the EDR calculation, preventing us from placing wings too wide during transitory calm or too narrow during elevated fear. Once RSAi confirms the credit, we enter the four-leg Iron Condor with defined risk and no stop losses. This is our Set and Forget approach. The Conservative tier, which we make available for PickMyTrade auto-execution, has delivered approximately 90 percent wins over multi-year backtests by staying inside the EDR-derived range nearly nine days out of ten. ALVH provides the protective overlay. We maintain the three-layer VIX call hedge in a 4/4/2 ratio per ten Iron Condor contracts, rolled on its own schedule to cut drawdowns by 35 to 40 percent in spikes without exceeding 2 percent annual cost of capital. Should price threaten a wing, the Temporal Theta Martingale and Theta Time Shift mechanics allow us to roll the position forward to 1-7 DTE on an EDR breach above 0.94 percent or VIX above 16, then roll back on a VWAP pullback to harvest additional theta. All position sizing remains at a maximum of 10 percent of account balance. VIX Risk Scaling further governs tier eligibility: with VIX at 17.95 we may use all three tiers, but above 20 we hold and let ALVH work. This disciplined fusion of EDR for range, RSAi for premium precision, and VIX9D for volatility context is what allows us to pursue consistent daily income while keeping maximum portfolio drawdown in the low double digits across 2015-2025 backtests. All trading involves substantial risk of loss and is not suitable for all investors.
