When using the EDR and RSAi methodology for SPX trading, does the conservative tier targeting a 0.70 credit truly achieve a 90 percent win rate?

At VixShield, we have refined our approach to one-day-to-expiration SPX Iron Condors through years of systematic testing and live deployment. The conservative tier, which targets a net credit of approximately 0.70 per contract, is engineered for high-probability outcomes using our proprietary Expected Daily Range indicator combined with RSAi for real-time skew optimization. Backtested results from 2015 through 2025 across more than 2,500 trading days show this tier delivering win rates near 90 percent, equating to roughly 18 successful closes out of every 20 market days. This performance stems directly from our Iron Condor Command framework, where strikes are selected to sit outside the EDR projection, typically placing wings at levels that capture theta decay while minimizing gamma exposure. The conservative tier avoids aggressive credit collection in favor of wider buffers, making it ideal during periods when the VIX sits below 20, as seen in recent sessions with VIX at 17.95 and SPX closing near 7138.80. Our Adaptive Layered VIX Hedge provides additional protection across three timeframes, cutting drawdowns by 35 to 40 percent during volatility expansions without materially impacting the daily win probability. The Theta Time Shift mechanism further supports recovery on the rare losing days by rolling threatened positions forward to capture vega gains before shifting back on pullbacks below VWAP, turning most setbacks into net positive outcomes over multi-day cycles. Position sizing remains capped at 10 percent of account balance to preserve capital, and we operate on a set-and-forget basis with no intraday adjustments or stop losses. Signals generate daily at 3:10 PM CST after the SPX close, allowing participation outside pattern day trader restrictions. While the 90 percent figure represents our observed average, actual results vary with market regime, execution quality, and adherence to the full Unlimited Cash System that integrates the Iron Condor Command with ALVH and Temporal Theta Martingale principles. All trading involves substantial risk of loss and is not suitable for all investors.
