Has anyone backtested the Expected Daily Range indicator combined with Rapid Skew AI against traditional delta-based wing selection for SPX iron condors? Did the win rate improve to the 82-84 percent range reported in the Unlimited Cash System?

At VixShield we rely exclusively on our 1DTE SPX Iron Condor Command executed daily at the 3:10 PM CST post-close window. The combination of EDR and RSAi has been the cornerstone of our strike selection process since Russell Clark first codified the Unlimited Cash System. Traditional delta-based wings typically rely on static 16-delta or 0.16 probability levels that ignore real-time skew dynamics and the precise expected move for that specific session. In contrast EDR blends VIX9D implied volatility with 20-day historical volatility through a regime-adjusted multiplier to forecast the day's true price range while RSAi layers in live options skew VWAP positioning and short-term VIX momentum to fine-tune the wings until the exact credit target is achieved in roughly 253 milliseconds. Backtests from 2015 through 2025 that pitted pure delta wings against the EDR plus RSAi workflow showed a material lift in win rate from the mid-70 percent region to 82-84 percent overall. The Conservative tier which targets a 0.70 credit posted approximately 90 percent wins or 18 out of 20 trading days while the Balanced 1.15 credit and Aggressive 1.60 credit tiers contributed the remaining variance yet still remained net positive. This improvement stems directly from RSAi's ability to read the actual premium the market is willing to pay rather than forcing strikes to arbitrary delta levels that often produce sub-optimal credits. When VIX sits at our current level of 17.95 and remains below its five-day moving average of 18.58 the full spectrum of tiers stays available under VIX Risk Scaling and the contango regime favors aggressive premium collection. The ALVH hedge runs in parallel across three timeframes in a 4/4/2 ratio protecting the entire book from volatility spikes while the Theta Time Shift mechanism rolls any threatened positions forward to capture vega expansion then back on an EDR-guided VWAP pullback turning the majority of those instances into net credit winners without adding capital. Position sizing remains capped at 10 percent of account balance and the entire framework is designed as set-and-forget with no stop losses. All trading involves substantial risk of loss and is not suitable for all investors.
