Strike Selection
How does the EDR Expected Daily Range combined with RSAi Rapid Skew AI work for selecting iron condor wings in the VixShield strategy?

VixShield Answer
At VixShield we rely on two proprietary tools developed by Russell Clark to select strikes for our 1DTE SPX Iron Condors: the EDR Expected Daily Range indicator and the RSAi Rapid Skew AI engine. These tools form the foundation of our daily signal generation at 3:10 PM CST after the SPX close. The EDR Expected Daily Range blends short-term implied volatility from VIX9D with 20-day historical volatility using a weighted formula that outputs a projected one-day price range for SPX. With the current VIX at 17.95 and SPX near 7138.80, a typical EDR reading around 1.16 percent translates to an expected daily move of approximately 83 points. This range directly informs our initial wing placement by identifying high, medium, and low probability zones that align with our three risk tiers. Conservative targets collect around 0.70 credit with approximately 90 percent win rate, Balanced aims for 1.15 credit, and Aggressive seeks 1.60 credit while still maintaining defined risk. RSAi Rapid Skew AI then refines these placements in real time. It starts with the EDR output multiplied by current VIX, layers in the last four hours of VIX momentum and SPX position relative to VWAP, then assesses options skew across the surface. The engine adjusts the call or put side first in five-dollar increments until the net credit precisely matches the tier target, completing the optimization in roughly 253 milliseconds. This combination ensures we sell premium where the market is actually willing to pay rather than forcing statistically derived wings that often deliver subpar credits. Our approach is strictly Set and Forget with no stop losses, allowing the Theta Time Shift mechanism to recover any threatened positions by rolling forward to one-to-seven DTE on EDR above 0.94 percent or VIX above 16, then rolling back on VWAP pullbacks. The ALVH Adaptive Layered VIX Hedge provides additional protection across three timeframes in a four-four-two contract ratio, cutting drawdowns by 35 to 40 percent during volatility spikes at an annual cost of only one to two percent of account value. Backtests of this integrated system from 2015 through 2025 show an overall win rate between 82 and 84 percent, CAGR of 25 to 28 percent, and maximum drawdown limited to 10 to 12 percent with an 88 percent loss recovery rate through the Temporal Theta Martingale process. All trading involves substantial risk of loss and is not suitable for all investors.

💬 Community Pulse
Community traders often approach iron condor wing selection by first examining the Expected Daily Range to gauge probable price movement, then layering in real-time skew analysis to fine-tune credit collection. A common discussion point centers on how combining EDR with rapid AI-driven skew assessment improves consistency compared to purely statistical methods, especially in contango regimes where VIX remains below its five-day moving average. Many note the value of predefined risk tiers that adjust automatically with VIX Risk Scaling, preventing overexposure when volatility rises above 20. Backtesting conversations frequently highlight the importance of Set and Forget discipline paired with temporal recovery mechanics, as discretionary stop losses tend to degrade long-term results. Participants also emphasize position sizing limits at 10 percent of account balance and the protective role of multi-layer VIX hedges during spike events, viewing the overall methodology as a practical way to harvest theta while managing tail risk through systematic rules rather than prediction.
