Does the RSAi skew analysis combined with the EDR filter truly maintain positions inside the expected daily range approximately 90 percent of the time on these 1DTE SPX iron condors?

At VixShield, we rely on the precise integration of RSAi and EDR to guide our 1DTE SPX Iron Condor Command entries each trading day. Russell Clark developed these tools within the SPX Mastery methodology to address the core challenge of short-term premium selling: capturing theta while staying within the Expected Daily Range the vast majority of sessions. The Conservative tier, targeting a 0.70 credit, has delivered an approximate 90 percent win rate, equating to roughly 18 successful days out of every 20 trading days across our 2015-2025 backtests. RSAi, or Rapid Skew AI, functions as our real-time signal engine. It analyzes current options skew, the implied volatility surface, VWAP positioning, and short-term VIX momentum to optimize strike selection in approximately 253 milliseconds. Rather than relying solely on statistical probabilities, RSAi dynamically adjusts wing placement to match the exact premium the market offers, typically landing at 0.65 to 0.75 for Conservative setups. This skew-aware approach helps avoid one-sided breaches that plague generic iron condor models. EDR, the Expected Daily Range indicator, complements RSAi by blending VIX9D implied volatility with 20-day historical volatility through a proprietary formula. It projects the day's likely price excursion and recommends High, Medium, or Low risk-tuned strikes. When combined, these filters ensure our short strikes are positioned beyond the projected one-standard-deviation move in most environments. For instance, with the current SPX close near 7138.80 and VIX at 17.95, EDR readings around 1.16 percent guide us to place wings that have historically contained price action on 82 to 90 percent of days depending on the tier. This framework operates under our Set and Forget discipline with no stop losses or intraday management. The Theta Time Shift mechanism provides zero-loss recovery by rolling threatened positions forward to 1-7 DTE during volatility expansions when EDR exceeds 0.94 percent or VIX rises above 16, then rolling back on VWAP pullbacks to harvest additional theta. Our ALVH Adaptive Layered VIX Hedge adds further protection, layering VIX calls across short, medium, and long tenors in a 4/4/2 ratio to cut drawdowns by 35-40 percent during spikes, all at an annual cost of just 1-2 percent of account value. VIX Risk Scaling further refines execution: with the current VIX at 17.95 below 20, all three tiers remain available, though we favor Conservative in moderate regimes. The Premium Gauge confirms calm conditions when credits stay near 0.70-0.85. These layered tools explain why our daily signals, fired at 3:05 PM CST after the SPX close, consistently align with the statistical edge of 1DTE premium decay. Position sizing remains at a maximum of 10 percent of account balance per trade to preserve capital through any outlier sessions. All trading involves substantial risk of loss and is not suitable for all investors.
