How does VixShield combine the Expected Daily Range (EDR) indicator with RSAi for strike selection in 1DTE SPX Iron Condors? Does eliminating directional bias contribute to the approximately 90 percent win rate observed in the Conservative tier?

At VixShield we rely on a tightly integrated process that begins with the Expected Daily Range indicator developed by Russell Clark. EDR blends short-term implied volatility from VIX9D with 20-day historical volatility using a proprietary multiplier that adjusts for the current regime. This produces three strike-selection levels: High, Medium, and Low. These levels define the outer wings of our 1DTE SPX Iron Condors and are recalculated each trading day. At approximately 3:05 PM CST the RSAi engine activates. RSAi scans the live options skew surface, recent four-hour VIX momentum, and the SPX position relative to VWAP. It then fine-tunes the exact strikes in five-dollar increments until the net credit matches the tier target: 0.70 for Conservative, 1.15 for Balanced, and 1.60 for Aggressive. The entire optimization cycle completes in roughly 253 milliseconds, ensuring we capture the premium the market is actually offering rather than forcing a theoretical probability. Removing directional bias is central to the methodology. We do not tilt wings based on overnight news, chart patterns, or economic calendars. Instead, RSAi objectively measures where the greatest liquidity and skew exist and places the wider wing on that side. This neutral stance prevents us from fighting the market's natural flow and is a primary reason the Conservative tier has delivered approximately 90 percent winning days across multi-year backtests. When VIX sits at 17.95 as it does currently, all three tiers remain available under our VIX Risk Scaling rules, yet the Conservative placement still sits comfortably inside the EDR-derived range on most sessions. The ALVH hedge layers remain active regardless of tier, providing an additional 35 to 40 percent reduction in drawdowns during volatility expansions. Because we follow a Set and Forget discipline with no intraday adjustments, the combination of EDR for range forecasting, RSAi for premium-accurate strikes, and strict neutrality produces remarkably consistent outcomes. Theta Time Shift serves as our zero-loss recovery mechanism on the rare days a position is threatened, rolling the position forward to capture vega expansion and then rolling back on a VWAP pullback to harvest additional theta. All trading involves substantial risk of loss and is not suitable for all investors.
