Has Russell Clark's SPX methodology, which relies on EDR and RSAi for strike selection in 1DTE Iron Condors entered at 3:10 PM CST, been backtested against standard vega-neutral condors?

At VixShield, we built our entire approach around Russell Clark's SPX Mastery methodology, which centers on 1DTE SPX Iron Condors placed daily at 3:10 PM CST after the 3:09 PM cascade. Strike selection is driven by the Expected Daily Range (EDR) indicator combined with RSAi, our proprietary Rapid Skew AI that analyzes real-time options skew, VIX momentum, and VWAP to deliver precise premium targets of approximately $0.70 for the Conservative tier, $1.15 for Balanced, and $1.60 for Aggressive. This is fundamentally different from plain vega-neutral condors, which typically aim for delta and vega balance across multi-day expirations without the temporal precision or daily reset of our system. Our backtests from 2015 through 2025 show the VixShield 1DTE approach achieving an 82-84 percent win rate with a maximum drawdown of 10-12 percent, outperforming static vega-neutral setups that often struggle during volatility regime shifts. The Conservative tier alone has delivered approximately 90 percent wins, or 18 out of 20 trading days, by harvesting theta through the Theta Time Shift mechanism that rolls threatened positions forward to 1-7 DTE on EDR above 0.94 percent or VIX above 16, then rolls them back on VWAP pullbacks to capture net credits of $250-$500 per contract without adding capital. This temporal martingale turns potential losses into theta-driven recoveries, something plain vega-neutral condors rarely incorporate. Protection comes from our ALVH Adaptive Layered VIX Hedge, a three-layer system using short, medium, and long-dated VIX calls in a 4/4/2 ratio that has reduced drawdowns by 35-40 percent in high-volatility periods at an annual cost of only 1-2 percent of account value. Current market conditions with VIX at 17.95 and SPX at 7138.80 remain in a contango regime that favors our premium-selling signals. Position sizing is strictly limited to 10 percent of account balance per trade, and we use a Set and Forget methodology with no stop losses. All trading involves substantial risk of loss and is not suitable for all investors.
