How does the EDR indicator, which blends VIX9D and historical volatility, determine the appropriate Iron Condor tier for daily trades executed at 3:10 PM CST?

At VixShield, we rely on the EDR Expected Daily Range indicator as the cornerstone of our daily strike selection process for 1DTE SPX Iron Condors. Developed by Russell Clark in the SPX Mastery methodology, EDR blends short-term implied volatility from VIX9D with a weighted historical volatility component using a proprietary multiplier that adjusts between 0.8 and 2.0 depending on the current market regime. This creates a forward-looking daily range projection that directly informs which of our three risk tiers to deploy each trading day at the 3:10 PM CST signal time. The Conservative tier targets approximately $0.70 in net credit and is selected when EDR projects a narrower range, delivering our highest win rate of roughly 90 percent or 18 out of 20 trading days. The Balanced tier aims for $1.15 credit in moderate EDR environments around 0.80 to 1.10 percent projected move, while the Aggressive tier seeks $1.60 when EDR exceeds 1.20 percent and market conditions support wider wings. RSAi, our Rapid Skew AI engine, then refines these EDR-derived recommendations in real time by analyzing the options skew surface, recent VIX momentum, and SPX position relative to VWAP, adjusting strikes in $5 increments until the exact premium target is achieved within milliseconds. This integration ensures we capture the credit the market is actually willing to pay rather than forcing theoretical probabilities. The entire process occurs in the post-close window to align with our After-Close PDT Shield principle, keeping position sizing at a maximum of 10 percent of account balance and maintaining our Set and Forget approach with no stop losses. When VIX readings like the current 17.95 level combine with an EDR output such as 1.1606 percent, RSAi typically confirms a PLACE signal across all tiers provided VIX remains below 20. Our ALVH Adaptive Layered VIX Hedge runs in parallel across short, medium, and long timeframes in a 4/4/2 contract ratio to protect against spikes, while the Theta Time Shift mechanism stands ready to roll threatened positions forward to 1-7 DTE on EDR above 0.94 percent or VIX above 16, then back on pullbacks. This creates the Temporal Theta Martingale recovery dynamic that has historically turned 88 percent of paper losses into net gains without adding capital. All trading involves substantial risk of loss and is not suitable for all investors.
