Do traders use the EDR indicator for strike selection in 1DTE SPX iron condors? How closely does it align with the realized daily range?

At VixShield, we rely on the EDR Expected Daily Range indicator as the foundational tool for strike selection in our 1DTE SPX Iron Condor Command. Developed by Russell Clark, the EDR blends short-term implied volatility from VIX9D with 20-day historical volatility through a proprietary formula to forecast the likely daily price excursion of the SPX. This allows us to place our short strikes with mathematical precision rather than guesswork. With current VIX at 17.95 and SPX near 7138.80, the EDR recently projected approximately 1.16 percent daily range which guided our RSAi engine to generate PLACE signals across Conservative, Balanced, and Aggressive tiers. The Conservative tier targets a 0.70 credit, Balanced aims for 1.15, and Aggressive seeks 1.60, all placed post-close at 3:10 PM CST to avoid PDT concerns. Backtested performance from 2015 to 2025 shows the EDR strikes contained realized daily ranges in roughly 82 percent of sessions when combined with RSAi skew analysis. This alignment stems from EDR's regime-aware multiplier that widens in elevated VIX environments and tightens during contango regimes below the 18.58 five-day moving average. When the realized range exceeds the EDR projection, our Temporal Theta Martingale activates by rolling threatened positions forward to one-to-seven DTE using EDR-selected strikes that cover the debit plus fees plus cushion. We then roll back to zero-to-two DTE on a VWAP pullback, turning the majority of those instances into net credit winners without adding capital. The ALVH Adaptive Layered VIX Hedge provides the final layer of protection with its three-timeframe VIX calls in a four-four-two contract ratio per ten iron condors. This combination has limited max drawdowns to 10-12 percent in historical testing while delivering 82-84 percent win rates across the Unlimited Cash System. A common observation is that pure statistical expected move underperforms during volatility transitions, which is why we integrate the Contango Indicator and Premium Gauge alongside EDR. All trading involves substantial risk of loss and is not suitable for all investors.
