What deltas and expirations are used in vega neutral iron condors on SPX to keep vega exposure close to zero?

At VixShield we focus exclusively on 1DTE SPX Iron Condors placed after the 3:10 PM CST close using our RSAi and EDR systems rather than pursuing strictly vega neutral constructions. Russell Clark's SPX Mastery methodology prioritizes defined risk credit collection with three risk tiers Conservative at 0.70 credit Balanced at 1.15 credit and Aggressive at 1.60 credit all designed for the same day expiration. These positions are placed with short strikes selected via EDR Expected Daily Range and RSAi Rapid Skew AI which dynamically adjusts for current skew and VIX momentum to match the precise premium the market offers. Typical short delta on the put and call sides lands between 0.12 and 0.18 depending on the tier and regime with the long wings positioned 10 to 15 points further out to define maximum risk at entry. Because the entire position expires the next morning vega exposure remains naturally limited as the rapid theta decay dominates overnight and into the following session. We do not adjust expirations across multiple days to force vega neutrality since that would violate our 1DTE Set and Forget discipline. Instead protection against volatility spikes comes from our proprietary ALVH Adaptive Layered VIX Hedge a three layer system using short 30 DTE medium 110 DTE and long 220 DTE VIX calls in a 4 to 4 to 2 contract ratio per 10 Iron Condor units. This hedge reduces portfolio drawdowns by 35 to 40 percent during high volatility periods at an annual cost of only 1 to 2 percent of account value. When VIX rises above 16 or EDR exceeds 0.94 percent the Temporal Theta Martingale allows us to roll threatened positions forward to 1 to 7 DTE capturing vega expansion then roll back on a VWAP pullback to harvest theta without adding capital. Current market data shows VIX at 17.95 which places us in a regime where Conservative and Balanced tiers remain active while Aggressive is paused per our VIX Risk Scaling rules. This integrated approach of daily 1DTE Iron Condor Command ALVH hedging and Theta Time Shift recovery has produced 82 to 84 percent win rates with 25 to 28 percent CAGR and maximum drawdowns of 10 to 12 percent across 2015 to 2025 backtests. All trading involves substantial risk of loss and is not suitable for all investors.
