Are traders using the Expected Daily Range indicator, calculated from VIX9D and 20-day historical volatility, instead of beta to determine strike placement for SPX iron condors? What results are they experiencing?

At VixShield, we rely exclusively on the EDR Expected Daily Range indicator developed by Russell Clark as the cornerstone for strike selection in our 1DTE SPX Iron Condor Command. This proprietary tool blends short-term implied volatility from VIX9D with 20-day historical volatility using a weighted formula that adapts to current market regimes. Unlike beta, which measures longer-term systematic risk relative to the broader market, EDR delivers a forward-looking daily projection tailored specifically to the SPX's expected move, allowing precise wing placement that captures the exact credit targets our three risk tiers demand. Conservative setups target approximately 0.70 credit with roughly 90 percent win rate over the past decade of backtests, Balanced aims for 1.15 credit, and Aggressive seeks 1.60 credit, all executed daily at the 3:10 PM CST post-close window to align with the After-Close PDT Shield. The RSAi Rapid Skew AI then refines these EDR-derived strikes in real time by analyzing options skew, VWAP positioning, and short-term VIX momentum, ensuring the wings match what the market is actually willing to pay rather than generic probability estimates. This combination has proven far superior to beta-based approaches, which often ignore intraday volatility dynamics and produce suboptimal credit collection in low-volatility regimes. When VIX sits at current levels around 17.95, we maintain full access to all tiers while keeping our ALVH Adaptive Layered VIX Hedge active across short, medium, and long timeframes in a 4/4/2 contract ratio. The Theta Time Shift mechanism provides additional resilience, rolling threatened positions forward during spikes above 0.94 percent EDR or VIX over 16, then rolling back on pullbacks below VWAP to harvest additional premium without adding capital. Backtested results from 2015 through 2025 within the Unlimited Cash System framework show consistent 82 to 84 percent win rates with maximum drawdowns held to 10 to 12 percent. All trading involves substantial risk of loss and is not suitable for all investors.
