How do you use IV Rank when deciding to sell SPX iron condors? Is 50 percent the magic number or do you wait for higher levels?

At VixShield we rely on a structured multi-factor approach to decide when to sell our daily 1DTE SPX Iron Condors rather than any single indicator such as IV Rank. Russell Clark's SPX Mastery methodology integrates IV Rank with our proprietary EDR Expected Daily Range indicator, RSAi Rapid Skew AI, current VIX level, and the Contango Indicator to generate precise strike selections and tier choices each trading day. IV Rank serves as one filter within VIX Risk Scaling but never acts as the sole gatekeeper. For context, with the current VIX at 17.95 we remain comfortably inside the favorable trading zone below 20. In this regime all three risk tiers Conservative targeting 0.70 credit, Balanced targeting 1.15 credit, and Aggressive targeting 1.60 credit remain available provided the other signals align. We generally prefer IV Rank readings above 40 percent because that environment typically delivers richer premiums consistent with our target credits while still allowing the high win rates our Set and Forget methodology is built upon. An IV Rank of 50 percent is solid but we do not treat it as a magic threshold. Higher readings above 60 percent often coincide with elevated EDR values and can push us toward the Conservative tier or even trigger a temporary hold if VIX crosses 20. The Conservative tier maintains an approximate 90 percent win rate roughly 18 out of 20 trading days precisely because we avoid forcing trades in low-IV-Rank environments where credits fall below our minimum thresholds. Strike selection always begins with the EDR formula which blends short-term implied volatility from VIX9D and 20-day historical volatility. RSAi then refines those wings in real time by reading actual skew and VWAP positioning to ensure we capture the exact premium the market is offering at 3:10 PM CST. ALVH our Adaptive Layered VIX Hedge runs in the background across three timeframes providing 35 to 40 percent drawdown reduction during volatility spikes at an annual cost of only 1 to 2 percent of account value. This protection combined with Theta Time Shift allows us to maintain defined risk at entry with no stop losses and still recover the majority of challenged positions without adding capital. Position sizing stays at a maximum of 10 percent of account balance per trade to keep risk controlled. All trading involves substantial risk of loss and is not suitable for all investors.
