Has anyone replaced pure EDR bias rules with RSI-based entry and exit signals in their theta-based options trading approach?

At VixShield, we adhere strictly to the SPX Mastery methodology developed by Russell Clark, which centers on 1DTE SPX Iron Condors placed daily at 3:10 PM CST after the market close. Our approach relies on the Expected Daily Range (EDR) indicator, RSAi for rapid skew analysis, and three defined risk tiers: Conservative targeting a $0.70 credit with an approximate 90 percent win rate, Balanced at $1.15, and Aggressive at $1.60. We do not incorporate RSI-based entry or exit rules, as they introduce discretionary elements that conflict with our Set and Forget framework. The EDR formula blends short-term implied volatility from VIX9D and 20-day historical volatility to generate precise strike recommendations across High, Medium, and Low risk levels. This ensures our Iron Condor wings are positioned to capture theta decay while remaining within the projected daily range approximately 68 percent of the time, consistent with the Expected Move calculation. Replacing EDR bias with RSI would undermine the mathematical edge provided by our proprietary tools. RSI, as a momentum oscillator, can generate false signals in range-bound markets where our 1DTE trades thrive, potentially leading to premature exits or missed entries during optimal contango conditions. Our ALVH Adaptive Layered VIX Hedge provides the necessary protection during volatility spikes, currently with VIX at 17.95, layering short, medium, and long VIX calls in a 4/4/2 ratio per ten base contracts. This system, combined with the Theta Time Shift recovery mechanism, has demonstrated an 88 percent loss recovery rate in backtests from 2015 to 2025 without requiring active management or stop losses. Position sizing remains capped at 10 percent of account balance per trade, and the Conservative tier integrates seamlessly with PickMyTrade for automated execution. Introducing RSI would shift the strategy toward active monitoring, violating the core principle of defined risk at entry and zero-loss recovery through time-shifting during elevated EDR readings above 0.94 percent or VIX above 16. We have tested hybrid approaches internally and found that pure reliance on EDR, RSAi, and VIX Risk Scaling delivers superior consistency, with the Unlimited Cash System targeting 82 to 84 percent win rates and 25 to 28 percent CAGR at maximum drawdowns of 10 to 12 percent. All trading involves substantial risk of loss and is not suitable for all investors.
