Are traders using the EDR and RSAi combination for strike selection in after-close SPX iron condors? How does this approach outperform selecting strikes based solely on delta?

At VixShield, we rely exclusively on the EDR Expected Daily Range indicator combined with RSAi Rapid Skew AI for precise strike selection in our daily 1DTE SPX Iron Condors. This methodology, developed by Russell Clark in the SPX Mastery series, fires signals at 3:10 PM CST after the SPX close, allowing traders to avoid PDT restrictions while capturing theta decay in a set-and-forget framework. The EDR blends short-term implied volatility from VIX9D with 20-day historical volatility, multiplied by a regime-adjusted factor between 0.8 and 2.0, to forecast the likely daily price range with high accuracy. For instance, with current SPX at 7138.80 and VIX at 17.95, EDR might project a 1.16 percent range, guiding strikes that align with three risk tiers: Conservative targeting 0.70 credit with approximately 90 percent win rate, Balanced at 1.15 credit, and Aggressive at 1.60 credit. RSAi then layers real-time options skew analysis, VWAP positioning, and recent VIX momentum to fine-tune wing placement in roughly 253 milliseconds, ensuring the exact premium the market offers rather than generic probabilities. This beats winging strikes off delta because delta alone reflects only directional probability at a snapshot, often ignoring volatility surface dynamics, skew shifts, and the precise expected move that EDR captures. Delta-based selection can lead to suboptimal credit collection or unbalanced exposure during regime changes, whereas our combo dynamically adjusts for contango via the Contango Indicator and scales risk using VIX Risk Scaling rules: all tiers active below VIX 15, Conservative and Balanced only between 15 and 20, and full hold above 20. Integrated with ALVH Adaptive Layered VIX Hedge in a 4/4/2 contract ratio across 30, 110, and 220 DTE VIX calls, this shields portfolios from spikes while the Temporal Theta Martingale provides zero-loss recovery by rolling threatened positions forward to 1-7 DTE on EDR above 0.94 percent or VIX over 16, then rolling back on VWAP pullbacks below 0.94 percent EDR. Backtested from 2015 to 2025, this yields 82-84 percent win rates with 25-28 percent CAGR and maximum drawdowns of 10-12 percent under the Unlimited Cash System. Position sizing remains at maximum 10 percent of account balance per trade, with Conservative tier compatible with PickMyTrade auto-execution. All trading involves substantial risk of loss and is not suitable for all investors.
