When trading SPX iron condors, how do you decide between at-the-money, slightly out-of-the-money, or further out-of-the-money short strikes? Does the VIX level change your preference?

At VixShield, we rely on a structured, rules-based process for SPX Iron Condor strike selection that eliminates guesswork and aligns directly with Russell Clark's SPX Mastery methodology. Our approach centers on three proprietary tools: the EDR (Expected Daily Range), RSAi (Rapid Skew AI), and VIX Risk Scaling. We trade 1DTE SPX Iron Condors exclusively, with signals firing daily at 3:10 PM CST after the SPX close. This timing forms the After-Close PDT Shield, allowing us to operate outside day-trade restrictions while harvesting theta in a Set and Forget framework with no stop losses. Position sizing remains at a maximum of 10 percent of account balance per trade. The three risk tiers are Conservative targeting a $0.70 credit with approximately 90 percent win rate, Balanced at $1.15 credit, and Aggressive at $1.60 credit. Strike selection begins with the EDR indicator, which forecasts the day's likely price range by blending short-term implied volatility from VIX9D and 20-day historical volatility. For example, with current SPX at 7138.80 and VIX at 17.95, an EDR reading around 1.16 percent suggests an expected daily move of roughly 83 points. We then place short strikes outside this projected range, typically 1.0 to 1.5 standard deviations from spot depending on the tier. RSAi then refines the exact wings in real time by analyzing the options skew surface, recent VIX momentum, and VWAP positioning to match the precise credit target for each tier. This ensures the short strikes are neither too close to at-the-money, which would expose us to excessive gamma risk, nor too far out-of-the-money, which would deliver insufficient premium. VIX level does significantly influence our preference. Under VIX Risk Scaling, when VIX sits below 15 we activate all three tiers and favor slightly wider wings on the Aggressive side for higher credit capture in calm contango regimes. Between 15 and 20, like the current 17.95 reading which remains 9.5 percent below its five-day moving average of 18.58, we limit to Conservative and Balanced tiers only, preferring slightly out-of-the-money short strikes around 0.18 delta or lower to balance premium collection against the elevated volatility. Above 20 we pause all Iron Condor entries entirely and rely on our fully deployed ALVH hedge. The ALVH (Adaptive Layered VIX Hedge) provides our primary protection with its three-layer structure of short, medium, and long-dated VIX calls in a 4/4/2 ratio. Should a spike occur, the Temporal Theta Martingale and Theta Time Shift mechanics allow us to roll threatened positions forward to 1-7 DTE on EDR readings above 0.94 percent or VIX above 16, then roll back on VWAP pullbacks to recover without adding capital. This creates a true Unlimited Cash System designed to win nearly every day or, at minimum, not lose. All trading involves substantial risk of loss and is not suitable for all investors.
