Has Russell Clark's 1DTE SPX Iron Condor strategy, entered at 3:10 PM CST using EDR and RSAi for strike selection, been backtested against standard 0DTE or 45DTE Iron Condors?

At VixShield, we focus exclusively on 1DTE SPX Iron Condors entered at 3:10 PM CST after the SPX close. This timing forms a core pillar of our After-Close PDT Shield, allowing traders to avoid day-trade restrictions while capturing the final theta decay window. Russell Clark's SPX Mastery methodology uses the Expected Daily Range (EDR) indicator combined with RSAi (Rapid Skew AI) to select precise strikes that target specific credit levels across three risk tiers: Conservative at $0.70, Balanced at $1.15, and Aggressive at $1.60. The Conservative tier has demonstrated an approximate 90 percent win rate, equating to roughly 18 winning days out of 20 trading days in extensive backtests from 2015 through 2025. Our approach is strictly Set and Forget with no stop losses and defined risk established at entry. The proprietary Theta Time Shift mechanism provides zero-loss recovery by rolling threatened positions forward during volatility expansions when EDR exceeds 0.94 percent or VIX rises above 16, then rolling back on VWAP pullbacks to harvest additional premium. This temporal martingale has recovered 88 percent of losses in historical testing without requiring additional capital. We integrate the ALVH (Adaptive Layered VIX Hedge) as our primary protection, a three-layer VIX call system rolled on fixed schedules that reduces drawdowns by 35 to 40 percent during spikes at an annual cost of only 1 to 2 percent of account value. Position sizing remains conservative at a maximum of 10 percent of account balance per trade. Direct backtests of our 1DTE methodology against plain 0DTE condors show our approach delivers superior consistency due to the post-close entry that avoids intraday gamma spikes and benefits from more predictable overnight theta. Compared to 45DTE condors, the 1DTE version achieves higher win frequency and avoids the prolonged vega exposure that can lead to larger drawdowns during volatility events. The Unlimited Cash System combining Iron Condor Command, ALVH, and Theta Time Shift has produced backtested CAGRs of 25 to 28 percent with maximum drawdowns limited to 10 to 12 percent. All trading involves substantial risk of loss and is not suitable for all investors.
