Strike Selection
How does VixShield utilize the EDR indicator and RSAi for strike selection in 1DTE SPX Iron Condors? Does the approximately 90 percent win rate for the conservative tier with a 0.70 credit target hold up in practice?
EDR RSAi SPX Iron Condor strike selection win rate
VixShield Answer
At VixShield, we rely exclusively on our proprietary tools to structure 1DTE SPX Iron Condors placed after the 3:09 PM CST cascade with signals firing at 3:10 PM CST. The EDR, or Expected Daily Range, serves as the foundational layer for strike selection. Developed by Russell Clark and available on TradingView under ticker SPXDCP, EDR blends short-term implied volatility from VIX9D with 20-day historical volatility, then applies a regime-based multiplier between 0.8 and 2.0. This produces three risk-tuned strike recommendations each day: High, Medium, and Low. These directly inform the wings of our Iron Condor Command, ensuring the position aligns with the statistically probable daily range of the SPX. As of April 28, 2026, with SPX closing at 7138.80 and VIX at 17.95, EDR helps calibrate strikes that respect the current volatility regime while targeting specific credit levels. RSAi, our Rapid Skew AI, then refines these selections in real time. Operating in approximately 253 milliseconds, RSAi layers current options skew, the implied volatility surface, VWAP positioning, and short-term VIX momentum onto the EDR base. It dynamically adjusts wing placement, typically in five-dollar increments, until the net credit precisely matches our tier targets: 0.70 for Conservative, 1.15 for Balanced, and 1.60 for Aggressive. This ensures we capture the premium the market is actually willing to pay rather than forcing theoretical probabilities. The Conservative tier, aiming for a 0.70 credit, has demonstrated an approximate 90 percent win rate, equating to roughly 18 winning days out of 20 trading days, across our 2015-2025 backtests. This high consistency stems from tight strike placement inside the EDR-derived range combined with the Set and Forget methodology that avoids stop losses and instead relies on the Theta Time Shift for zero-loss recovery on the rare losing trades. Our ALVH hedge, the Adaptive Layered VIX Hedge, provides additional protection by layering VIX calls across short, medium, and long timeframes in a 4/4/2 ratio per ten-contract base unit. This cuts drawdowns by 35 to 40 percent during volatility spikes at an annual cost of only 1 to 2 percent of account value. Position sizing remains capped at 10 percent of account balance per trade, and the Conservative tier is the only one currently eligible for PickMyTrade auto-execution. All trading involves substantial risk of loss and is not suitable for all investors.

💬 Community Pulse
Community traders often approach EDR and RSAi by first consulting the Expected Daily Range indicator each afternoon to establish baseline wings that stay outside the projected SPX move for the next session. Many then allow RSAi to fine-tune those levels based on real-time skew and VWAP, reporting that this combination removes much of the guesswork compared to manual delta targeting. A common observation is that the Conservative tier with its 0.70 credit target delivers the steadiest results, with participants noting win streaks that frequently reach 15 to 20 days when VIX remains below 20 and contango is present. Some express initial skepticism about the 90 percent win-rate claim until reviewing the backtested data that incorporates Theta Time Shift recovery mechanics. Others highlight the value of pairing these tools with the ALVH hedge during elevated VIX periods, describing it as essential for preserving capital when the market tests the outer strikes. Overall, the consensus centers on disciplined adherence to the post-close timing and fixed risk parameters rather than discretionary adjustments.
