How much does strictly following the EDR Expected Daily Range and RSAi skew signals improve the win rate of 1DTE SPX iron condors compared to discretionary strike selection?

At VixShield, we have found that strictly following the EDR Expected Daily Range and RSAi skew signals dramatically improves the win rate of our 1DTE SPX iron condors compared to discretionary strike selection. Russell Clark's SPX Mastery methodology centers on these two proprietary tools to remove emotion and optimize for the precise premium the market offers each day. The EDR indicator blends short-term implied volatility from VIX9D with 20-day historical volatility to forecast the day's likely range, generating High, Medium, and Low strike recommendations that align with our three risk tiers: Conservative targeting $0.70 credit, Balanced at $1.15, and Aggressive at $1.60. RSAi then layers real-time skew analysis, VWAP positioning, and recent VIX momentum to fine-tune wing placement, ensuring we capture the exact credit without guessing. Backtested results from 2015 to 2025 show the Conservative tier achieving approximately 90 percent wins, or about 18 out of 20 trading days, when signals are followed precisely. In contrast, discretionary approaches that ignore EDR often result in strikes too close to the current price, leading to win rates dropping into the 65-75 percent range as gamma risk increases near expiration. Our signals fire daily at 3:10 PM CST after the SPX close, allowing the After-Close PDT Shield to keep us out of day-trading limitations while theta works overnight. This Set and Forget methodology incorporates no stop losses; instead, the Theta Time Shift mechanism rolls threatened positions forward to 1-7 DTE when EDR exceeds 0.94 percent or VIX rises above 16, then rolls back on VWAP pullbacks to harvest recovery credits of $250-$500 per contract. The ALVH Adaptive Layered VIX Hedge provides additional protection across three timeframes, cutting drawdowns by 35-40 percent during spikes at an annual cost of only 1-2 percent of account value. Position sizing remains at a maximum of 10 percent of balance per trade to maintain consistency. With current VIX at 17.95, we remain in a regime where all tiers are available, though we monitor the Contango Indicator closely. All trading involves substantial risk of loss and is not suitable for all investors.
