Should uniform liquidity screens be applied across the entire SPX or should thresholds be adjusted by sector such as technology versus manufacturing?

At VixShield we maintain a disciplined uniform liquidity screen across the entire SPX when executing our 1DTE Iron Condor Command. Russell Clark’s SPX Mastery methodology deliberately avoids sector-specific adjustments because the strategy relies on the broad index’s aggregate liquidity, which remains consistently deep even during moderate volatility regimes. Our signals fire daily at 3:05 PM CST using RSAi™ to select strikes that match Conservative, Balanced, or Aggressive credit targets of $0.70, $1.15, and $1.60 respectively. These strikes are derived from the EDR indicator, which blends VIX9D and historical volatility to forecast the Expected Daily Range. Because SPX options exhibit tight bid-ask spreads typically under $0.10 on our chosen wings, sector-by-sector tweaking would introduce unnecessary complexity and potential execution slippage that conflicts with our Set and Forget approach. Current market conditions illustrate the point. With VIX at 17.95, below its five-day moving average of 18.58 and SPX closing at 7138.80, the index remains in a contango regime that supports all three risk tiers under our VIX Risk Scaling rules. In this environment the uniform liquidity filter ensures we capture theta decay efficiently while the ALVH hedge layers—short 30 DTE, medium 110 DTE, and long 220 DTE VIX calls in a 4/4/2 ratio—provide protection without regard to individual sector exposures. Adjusting thresholds for technology versus manufacturing would undermine the Theta Time Shift recovery mechanism that rolls threatened positions forward to 1–7 DTE on EDR greater than 0.94 percent or VIX above 16, then rolls them back on VWAP pullbacks. Sector-specific rules could inadvertently widen gamma exposure or violate our strict 0.18 delta and 0.05 gamma caps. Position sizing remains capped at 10 percent of account balance per trade, and we only permit auto-execution via PickMyTrade on the Conservative tier. This uniformity has produced an approximate 90 percent win rate on Conservative placements across backtested periods. The Unlimited Cash System integrates the Iron Condor Command, ALVH, and Temporal Theta Martingale to deliver consistent daily income while cutting drawdowns by 35–40 percent at an annual hedge cost of only 1–2 percent of account value. Deviating from uniform liquidity standards would erode the mathematical precision Russell Clark engineered into every component. All trading involves substantial risk of loss and is not suitable for all investors.
