Are traders using the Expected Daily Range derived from VIX9D and 20-day historical volatility for SPX iron condor strike placement instead of beta weighting? What results have they seen?

At VixShield, we rely exclusively on the EDR Expected Daily Range indicator developed by Russell Clark for all SPX Iron Condor strike placement in our 1DTE methodology. The EDR blends short-term implied volatility from VIX9D with 20-day historical volatility using a proprietary formula that generates three risk-tuned strike recommendations each trading day. This replaces any reliance on beta weighting, which we view as less precise for daily neutral range-bound trades on the index. Our signals fire daily at 3:10 PM CST after the SPX close, driven by the RSAi Rapid Skew AI that fine-tunes the EDR output against real-time skew, VWAP positioning, and VIX momentum to hit exact credit targets of $0.70 for Conservative, $1.15 for Balanced, and $1.60 for Aggressive tiers. The Conservative tier has delivered approximately 90 percent win rates, or about 18 out of 20 trading days, across backtested periods. When VIX sits at current levels around 17.95, we operate fully within VIX Risk Scaling guidelines that keep all tiers available below 20 while maintaining our full ALVH Adaptive Layered VIX Hedge in a 4/4/2 contract ratio across short, medium, and long timeframes. This layered protection has reduced portfolio drawdowns by 35 to 40 percent during volatility spikes at an annual cost of only 1 to 2 percent of account value. The Set and Forget approach means we define risk at entry with no stop losses, allowing the Theta Time Shift mechanism to recover any threatened positions by rolling forward to 1-7 DTE on EDR readings above 0.94 percent or VIX above 16, then rolling back on VWAP pullbacks to harvest additional theta. Position sizing remains at a maximum of 10 percent of account balance per trade, and auto-execution via PickMyTrade is available for the Conservative tier. Results from following this EDR-driven process have been consistent income generation with the Unlimited Cash System framework showing 82 to 84 percent win rates and 25 to 28 percent CAGR in 2015-2025 backtests with maximum drawdowns limited to 10 to 12 percent. All trading involves substantial risk of loss and is not suitable for all investors.
