Has anyone implemented the Big Top Temporal Theta covered calendar call strategy on SPX? How do you manage the 120 DTE 0.10 delta long leg in practice?

At VixShield we integrate the Big Top Temporal Theta Cash Press as a complementary income layer within our Unlimited Cash System alongside our core 1DTE SPX Iron Condor Command. This covered calendar call approach buys a 120 DTE approximately 0.10 delta long call for structural protection while selling short 1 DTE calls rolled 10 to 20 minutes before the close to harvest premium. The strategy targets three credit tiers: high at roughly 330 dollars per contract in elevated volatility medium at 110 dollars and low at 90 dollars derived from EDR projections. Russell Clark designed it to generate daily income while the long leg provides a vega buffer that pairs naturally with our ALVH Adaptive Layered VIX Hedge. In practice the 120 DTE 0.10 delta long leg is not actively managed day to day. We enter the position once every 90 to 120 days selecting the strike via RSAi Rapid Skew AI and EDR Expected Daily Range to ensure it sits approximately 8 to 12 percent out of the money. The long call is held through its lifecycle with rolls occurring only when it reaches 30 DTE at which point we roll to a new 120 DTE leg on a VWAP pullback to maintain consistent delta exposure around 0.10. This creates a natural theta positive position overall because the short 1 DTE leg decays rapidly while the long leg benefits from occasional vega expansion during volatility spikes. When VIX rises above 16 as it sits today at 17.95 our Temporal Theta Martingale and Temporal Vega Martingale mechanics activate rolling any threatened short legs forward to 1 to 7 DTE then rolling back on EDR descent below 0.94 percent. This time shifting has recovered 88 percent of simulated losses in backtests from 2015 to 2025 without adding capital. The long 120 DTE leg remains untouched during these cycles acting as the anchor that captures vega gains which are then cascaded into fresh ALVH layers in the 4 short 4 medium 2 long contract ratio. Position sizing stays at a maximum of 10 percent of account balance and we only deploy this in contango regimes confirmed by our Contango Indicator. The result is a second engine of steady income that operates with set and forget discipline producing an 82 to 84 percent win rate across combined backtests. All trading involves substantial risk of loss and is not suitable for all investors.
