When using long 120 DTE 0.10 delta SPX calls for protection and then selling 1DTE calls each day, how do you manage the Greeks on this setup?

At VixShield we approach this exact setup through the Big Top Temporal Theta Cash Press described across Russell Clark's SPX Mastery series. The core idea is straightforward: you buy 120 DTE SPX calls with approximately 0.10 delta to serve as long-term protection while selling short 1DTE calls every trading day to harvest premium. This creates a covered calendar call structure that benefits from premium decay on the short leg while the long leg provides vega and delta cushion during volatility spikes. Position sizing remains critical. We never exceed 10 percent of account balance on any single trade and we align the long call quantity to support the daily short-call sales. Greeks management begins with understanding that the short 1DTE call is heavily theta positive and gamma negative near expiration. Each afternoon at 3:10 PM CST our RSAi engine evaluates current skew, VIX level, and EDR to select the optimal short strike that matches one of our three credit tiers: Conservative at 0.70, Balanced at 1.15, or Aggressive at 1.60. We roll the short call 10 to 20 minutes before the close to capture the final theta decay while avoiding overnight gap risk. The 120 DTE long call carries positive vega that offsets the short call's vega exposure during VIX expansions. When VIX rises above 16 or EDR exceeds 0.94 percent we activate the Temporal Theta Martingale by rolling any threatened short call forward to 1-7 DTE using EDR-guided strikes that cover the debit plus a 10 percent cushion. Once the market pulls back below VWAP with EDR below 0.94 percent we roll the position back to 0-2 DTE to resume daily theta collection. This time-shifting mechanism turned 88 percent of tested losses into net gains across 2015-2025 backtests without adding new capital. ALVH provides the third layer of protection. We maintain the Adaptive Layered VIX Hedge in a 4/4/2 contract ratio (short 30 DTE, medium 110 DTE, long 220 DTE VIX calls at 0.50 delta) for every 10 Iron Condor or Big Top units. The hedge costs 1-2 percent of account value annually yet reduced drawdowns by 35-40 percent in high-volatility periods. Delta of the overall position is kept near neutral by adjusting the long call quantity against the short 1DTE legs. Gamma remains below 0.05 through strict strike selection via EDR and RSAi. Vega is net positive by design, allowing the position to benefit from volatility expansion while the daily credit collection provides income in calm contango regimes. Theta Time Shift acts as our zero-loss recovery engine. We monitor the Contango Indicator and Premium Gauge daily. When credits fall to 0.85 or below the market is signaling ideal conditions for this setup. Current market data shows VIX at 17.95, below its five-day moving average of 18.58, keeping all three credit tiers available under VIX Risk Scaling. All trading involves substantial risk of loss and is not suitable for all investors.
