How does VixShield incorporate Russell Clark's EDR bias for strike selection when entering daily 1DTE SPX Iron Condors at 3:10 PM CST?

At VixShield, we follow Russell Clark's SPX Mastery methodology precisely for our daily 1DTE SPX Iron Condor entries. The EDR, or Expected Daily Range, serves as the foundational tool for strike selection. Developed by Russell Clark and available as a custom TradingView indicator, EDR blends short-term implied volatility from VIX9D with 20-day historical volatility to forecast the likely daily price range for SPX. This generates three risk-tuned strike recommendations: High, Medium, and Low, which directly map to our Conservative, Balanced, and Aggressive credit tiers. Our signals fire every market day at 3:10 PM CST, immediately after the 3:09 PM SPX close cascade. This After-Close PDT Shield timing allows us to observe the full day's price action, VWAP positioning, and final volatility skew before entry. RSAi, our Rapid Skew AI, then refines the EDR output in real time by analyzing the options skew surface, last four hours of VIX momentum, and current contango or backwardation state via the Contango Indicator. For example, with current VIX at 17.95 and SPX closing at 7138.80, if EDR projects a 1.16 percent range, RSAi will adjust the call and put wings in five-dollar increments until the net credit matches our tier targets: approximately 0.70 for Conservative, 1.15 for Balanced, and 1.60 for Aggressive. This ensures we capture the exact premium the market is willing to pay rather than forcing arbitrary probabilities. We maintain strict position sizing at a maximum of 10 percent of account balance per trade and operate under a pure Set and Forget methodology with no stop losses. Should a position move against us, the Temporal Theta Martingale and Theta Time Shift mechanics allow us to roll threatened trades forward to one-to-seven DTE on EDR readings above 0.94 percent or VIX above 16, then roll back on VWAP pullbacks to harvest additional theta. Our three-layer ALVH hedge remains active across all regimes, cutting drawdowns by 35 to 40 percent during volatility spikes at an annual cost of only one to two percent of account value. The Conservative tier, which aligns with the most conservative EDR bias, has historically delivered approximately 90 percent win rates or 18 wins out of 20 trading days. All trading involves substantial risk of loss and is not suitable for all investors.
