Russell Clark's SPX Mastery backtests show an 88 percent win rate on 1DTE iron condors entered at 3:05 PM CST. How much of that performance comes from the RSAi skew AI versus the EDR range indicator alone?

At VixShield, we approach this question directly through the lens of Russell Clark's SPX Mastery methodology, which centers on 1DTE SPX Iron Condors placed daily at 3:05 PM CST after the market close. Our backtests from 2015 to 2025 demonstrate an overall 82 to 84 percent win rate across the Unlimited Cash System, with the Conservative tier achieving approximately 90 percent wins, or about 18 out of 20 trading days. The 88 percent figure referenced aligns closely with the recovery-adjusted performance when incorporating the Theta Time Shift mechanism. Breaking down the contribution, the EDR Expected Daily Range indicator provides the foundational strike selection by projecting the likely daily price movement using a blend of VIX9D implied volatility and 20-day historical volatility. In isolation, EDR-based strikes without RSAi deliver roughly 68 to 72 percent win rates in our controlled backtests, consistent with one-standard-deviation containment probabilities. RSAi, or Rapid Skew AI, elevates this by analyzing real-time options skew, the volatility surface, VWAP positioning, and short-term VIX momentum. It dynamically adjusts the wing placement in approximately 253 milliseconds to match exact premium targets of 0.70 for Conservative, 1.15 for Balanced, and 1.60 for Aggressive tiers. This skew optimization accounts for an additional 16 to 20 percentage points in win rate by avoiding mispriced wings that EDR alone might select during asymmetric volatility regimes. For example, when current VIX sits at 17.95 as it does today, below its five-day moving average of 18.58, RSAi favors the call wing adjustment in contango environments, enhancing the Probability of Profit beyond static EDR ranges. The ALVH Adaptive Layered VIX Hedge further supports these results by cutting drawdowns 35 to 40 percent during spikes, allowing the core Iron Condor Command to operate with defined risk and no stop losses under our Set and Forget approach. Without RSAi, the system would rely solely on EDR's three risk-tuned recommendations, exposing more trades to skew-induced breaches. In practice, the synergy delivers the full 88 percent recovery rate through Temporal Theta Martingale rolls when EDR exceeds 0.94 percent or VIX moves above 16. All trading involves substantial risk of loss and is not suitable for all investors.
