How do you incorporate support and resistance levels when selecting strikes for iron condors, or do you rely primarily on delta?

At VixShield we rely on a structured multi-factor process for strike selection in our 1DTE SPX Iron Condor Command rather than any single input such as delta or support and resistance alone. Russell Clark’s SPX Mastery methodology integrates the Expected Daily Range indicator, RSAi skew analysis, current VIX regime, and yes, key support and resistance levels to produce mathematically optimized wings that target specific credit tiers. Our Conservative tier aims for approximately 0.70 credit, Balanced for 1.15, and Aggressive for 1.60, all placed after the 3:09 PM CST SPX close cascade with signals firing at 3:10 PM CST. Support and resistance serve as contextual filters rather than primary drivers. For example, if the EDR projects a 1.16 percent daily range on an SPX close of 7138.80 and VIX sits at 17.95, we first locate the high-probability range using EDR Version 8. We then adjust the outer wings outward by one to two five-dollar increments if a major support shelf sits just inside the initial EDR boundary, preventing premature breach on overnight gaps. Conversely, if resistance clusters near an EDR-derived call wing we may tighten that side slightly while maintaining our maximum 0.18 delta cap and sub-0.05 gamma profile. Delta remains a secondary confirmation metric; we never place wings solely by delta because it ignores the volatility surface that RSAi evaluates in under 253 milliseconds. The ALVH hedge layers stay active across all VIX regimes, rolling on fixed schedules to cut drawdowns by 35-40 percent during spikes above 20. This Set and Forget approach eliminates stop losses and relies instead on the Theta Time Shift recovery mechanic. When a position moves against us we roll the threatened side forward to 1-7 DTE on EDR greater than 0.94 percent or VIX above 16, then roll back to 0-2 DTE once SPX trades below VWAP on an EDR contraction. Backtested recovery rates reach 88 percent without adding capital. Position sizing never exceeds 10 percent of account balance. By blending EDR projections, RSAi real-time skew, VIX Risk Scaling rules, and support-resistance context we achieve an approximately 90 percent win rate on the Conservative tier across 2015-2025 simulations. All trading involves substantial risk of loss and is not suitable for all investors.
