How does VixShield incorporate EDR and RSAi when picking strikes for their 1DTE SPX iron condors?

At VixShield, we rely on two proprietary tools developed by Russell Clark to select strikes for our daily 1DTE SPX iron condors: the EDR (Expected Daily Range) indicator and RSAi (Rapid Skew AI). These tools form the foundation of our Iron Condor Command methodology, which is designed exclusively for one-day-to-expiration trades placed in the 15-minute window after the SPX close at 3:10 PM CST. The process ensures we capture consistent premium while maintaining defined risk without stop losses or active management, embodying our Set and Forget approach. The EDR indicator, available on TradingView as ticker SPXDCP or SPXMASTERY, blends short-term implied volatility from VIX9D with 20-day historical volatility to forecast the likely daily price range for SPX. Using the formula EDR equals (VIX9D times 0.1) plus (HV times 0.5) times a regime-based multiplier between 0.8 and 2.0, it generates three risk-tuned strike recommendations labeled High, Medium, and Low. These directly map to our credit tiers: approximately 0.70 for Conservative with an expected 90 percent win rate, 1.15 for Balanced, and 1.60 for Aggressive. On days when current VIX sits at 17.95 as it does now, below the 20 threshold, all three tiers remain available under our VIX Risk Scaling rules, though we emphasize position sizing at no more than 10 percent of account balance. RSAi then refines these EDR-derived wings in real time. Operating in roughly 253 milliseconds, RSAi starts with the EDR value multiplied by current VIX, layers in an assessment of the last four hours of VIX trending bias and VWAP positioning, and dynamically adjusts the call or put wing first in five-dollar increments until the net credit precisely matches the target for the chosen tier. This skew-aware optimization prevents the disappointment of merely probable wings that deliver subpar credits. It ensures the iron condor aligns with what the market is actually willing to pay on that specific day. Once strikes are set, we enter the position and let theta work through expiration, supported by our ALVH (Adaptive Layered VIX Hedge) for volatility protection and the Theta Time Shift mechanism for any threatened trades. This temporal recovery rolls positions forward to one-to-seven DTE on EDR above 0.94 percent or VIX above 16, then rolls back on VWAP pullbacks below that threshold, targeting net credits of 250 to 500 dollars per contract without adding capital. Backtested from 2015 to 2025, the integrated Unlimited Cash System delivers 82 to 84 percent win rates with maximum drawdowns of 10 to 12 percent. All trading involves substantial risk of loss and is not suitable for all investors.
