The article references rolling the short 1 DTE call 10 to 20 minutes before close using EDR bias. What does that strike selection process look like on a day-to-day basis?

At VixShield, we approach the Big Top Temporal Theta Cash Press as a core component of our daily income generation within the Unlimited Cash System. This covered calendar call strategy on SPX combines a long 120 DTE call purchased at approximately 0.10 delta for structural protection with the sale of a short 1 DTE call rolled 10 to 20 minutes before the close. The roll is guided by EDR projections and RSAi skew analysis to target specific premium tiers while maintaining defined risk parameters. Our methodology emphasizes 1DTE execution aligned with the 3:10 PM CST signal window to harness Theta Time Shift mechanics without active intraday management. Strike selection for the short call roll follows a disciplined process driven by the EDR indicator, which blends VIX9D and 20-day historical volatility to forecast the Expected Daily Range. On a typical trading day with VIX at 17.95 and SPX near 7138.80, the EDR might project a 1.16 percent daily range, equating to roughly 83 points. We begin by identifying the at-the-money strike closest to the current SPX level, then reference the three EDR-derived risk tiers: High, Medium, and Low. For the Conservative tier targeting around 0.70 credit, we favor the Low EDR strike, typically 40 to 50 points out-of-the-money on the call side to balance premium collection against breach probability. The Balanced tier at 1.15 credit shifts to the Medium strike, often 25 to 35 points OTM, while the Aggressive tier seeks 1.60 credit by selling closer to the High EDR boundary, approximately 15 to 25 points OTM. RSAi then applies real-time skew assessment from the options surface and VWAP positioning, adjusting the exact strike in five-point increments until the net credit matches the tier target within a 253-millisecond computation window. This occurs daily in contango regimes where VIX remains below its five-day moving average of 18.58, allowing all three tiers under our VIX Risk Scaling rules. The roll itself is executed 10 to 20 minutes pre-close to capture final theta decay while avoiding assignment risk near the bell. If the position moves against us intraday, the Temporal Theta Martingale activates by rolling the threatened short call forward to 1-7 DTE on EDR exceeding 0.94 percent or VIX above 16, then rolling back to 0-2 DTE on a VWAP pullback to harvest additional premium cycles targeting 250 to 500 dollars net credit per contract. This time-shifting approach, combined with our ALVH three-layer VIX hedge in a 4/4/2 ratio, has demonstrated 88 percent loss recovery in backtests from 2015 to 2025 while keeping maximum drawdowns between 10 and 12 percent. Position sizing remains capped at 10 percent of account balance, and we maintain a set-and-forget discipline with no stop losses. All trading involves substantial risk of loss and is not suitable for all investors.
