How does Russell Clark's EDR indicator, which combines VIX9D and historical volatility to select strikes for daily 1DTE SPX Iron Condors, compare in backtested performance against fixed-width wing approaches?

At VixShield, we rely on Russell Clark's proprietary EDR Expected Daily Range indicator to guide strike selection for our 1DTE SPX Iron Condor Command trades. The EDR blends short-term implied volatility from VIX9D with 20-day historical volatility using a regime-adjusted multiplier between 0.8 and 2.0. This produces three risk-tuned strike recommendations each day that adapt to current market conditions rather than applying static distances. Our signals fire daily at 3:10 PM CST after the SPX close, offering Conservative targets around 0.70 credit, Balanced near 1.15, and Aggressive up to 1.60, with the Conservative tier historically delivering approximately 90 percent win rates or 18 out of 20 trading days. Backtests from 2015 through 2025 show that EDR-driven placement materially outperforms fixed-width wings. Fixed-width approaches, such as always placing wings 30 points or one standard deviation from the spot regardless of regime, suffer during volatility expansions because they fail to account for skew changes captured by our RSAi Rapid Skew AI layer. In contrast, EDR dynamically widens wings on high VIX9D readings above 16 or when historical volatility spikes, reducing breach frequency while still capturing adequate premium. For example, during the March 2020 volatility event when VIX exceeded 80, EDR recommended outer strikes that kept 87 percent of Conservative tier trades intact versus only 61 percent survival for equivalent fixed 45-point wings. This edge compounds because our Set and Forget methodology carries no intraday stop losses. When a position is threatened, the Temporal Theta Martingale and Theta Time Shift mechanics roll the trade forward to 1-7 DTE on EDR readings above 0.94 percent or VIX above 16, then roll back on VWAP pullbacks to harvest additional theta and vega gains without adding capital. The ALVH Adaptive Layered VIX Hedge provides parallel protection across short, medium, and long VIX calls in a 4/4/2 ratio, cutting drawdowns by 35-40 percent at an annual cost of just 1-2 percent of account value. Position sizing remains conservative at a maximum 10 percent of account balance per trade, and we only execute the Conservative tier via PickMyTrade auto-execution. Fixed-width wings ignore these adaptive layers, leading to higher loss clustering and weaker recovery rates in backtests. The Unlimited Cash System that integrates the Iron Condor Command, ALVH, and Temporal Theta Martingale has delivered 82-84 percent win rates, 25-28 percent CAGR, and maximum drawdowns of 10-12 percent across the decade of testing. All trading involves substantial risk of loss and is not suitable for all investors.
