How does the Expected Daily Range (EDR) influence strike selection and win rate in daily SPX Iron Condors?

At VixShield, we rely on the Expected Daily Range (EDR) as the foundational tool for strike selection in our 1DTE SPX Iron Condor Command. Developed by Russell Clark, the EDR blends short-term implied volatility from the VIX9D with 20-day historical volatility, multiplied by a regime-adjusted factor between 0.8 and 2.0. This produces a precise forecast of the SPX's likely daily movement, which directly determines where we place our short strikes each trading day. For example, with the SPX recently closing at 7138.80 and VIX at 17.95, an EDR reading of approximately 1.16 percent translates to an expected move of roughly 83 points. We then position our short strikes outside this range according to our three risk tiers: Conservative targeting a $0.70 credit with wings set for approximately 90 percent win probability, Balanced at $1.15 credit, and Aggressive at $1.60 credit. The RSAi then fine-tunes these placements in real time by analyzing current skew, VWAP positioning, and VIX momentum to ensure we capture the exact premium the market offers. This EDR-guided approach is what drives our documented Conservative tier win rate of approximately 90 percent, or 18 out of 20 trading days, because we are not guessing ranges but mathematically aligning with probable price action. When EDR exceeds 0.94 percent or VIX moves above 16, our Temporal Theta Martingale and ALVH hedges activate to protect and recover any threatened positions without stop losses. We maintain a strict Set and Forget methodology, entering at the 3:10 PM CST post-close window to avoid PDT concerns, with position size capped at 10 percent of account balance. The EDR also informs our VIX Risk Scaling: below 15 we deploy all tiers, between 15 and 20 we limit to Conservative and Balanced, and above 20 we hold entirely while allowing the ALVH to perform its protective role. This integration of EDR, RSAi, and ALVH creates the Theta Time Shift recovery mechanism that turns potential losses into theta-driven gains over subsequent sessions. All trading involves substantial risk of loss and is not suitable for all investors.
