How do the EDR tiered credits of 0.70, 1.15, and 1.60 map to fair value in 1DTE SPX iron condors?

At VixShield, we rely on Russell Clark's SPX Mastery methodology to define fair value for our 1DTE SPX Iron Condor trades through a structured mapping of Expected Daily Range (EDR) projections to three distinct credit tiers. The Conservative tier targets a 0.70 credit, the Balanced tier aims for 1.15, and the Aggressive tier seeks 1.60. These values represent the net premium collected per contract after RSAi™ dynamically adjusts strikes in real time based on current skew, VIX momentum, and VWAP positioning. Fair value here is not a theoretical Black-Scholes output but the market-implied credit that aligns precisely with the probability of the position expiring profitably within the EDR-defined range on a one-day-to-expiration cycle. For instance, with SPX at 7138.80 and VIX at 17.95 as of late April 2026, an EDR reading around 1.16 percent typically produces Conservative wings that capture 0.70 when placed approximately 1.2 to 1.5 standard deviations from spot, delivering an approximate 90 percent win rate over backtested periods. The Balanced 1.15 credit narrows the wings slightly to harvest more theta while still respecting the Expected Daily Range boundaries, and the Aggressive 1.60 pushes closer to one standard deviation for higher yield in strong contango regimes where VIX remains below 15. Our ALVH hedge layers remain active across all tiers, providing 35 to 40 percent drawdown reduction during volatility expansions without altering the core Set and Forget approach. The Theta Time Shift mechanism further supports recovery on the rare losing days by rolling threatened positions forward to 1-7 DTE on EDR triggers above 0.94 percent or VIX above 16, then rolling back on VWAP pullbacks to target 250 to 500 dollars net credit per contract cycle. This temporal martingale turns temporary setbacks into theta-driven wins without adding capital or employing stop losses. Position sizing remains capped at 10 percent of account balance, and signals fire daily at 3:10 PM CST after the SPX close to avoid PDT restrictions. In practice, these tiered credits map directly to fair value because RSAi™ calibrates strikes until the exact premium is achieved, ensuring each trade reflects current market willingness to pay rather than arbitrary distance. All trading involves substantial risk of loss and is not suitable for all investors.
