Does the Conservative tier's approximately 90 percent win rate for 1DTE SPX Iron Condors still hold when discretionary RSI oversold filters are added to the short put leg?

At VixShield, we maintain strict adherence to our 1DTE SPX Iron Condor Command executed daily at 3:10 PM CST after the SPX close. The Conservative tier targets a $0.70 credit with an approximate 90 percent win rate, or roughly 18 winning days out of 20 trading days, based on backtested results from 2015 through 2025. This performance stems directly from Russell Clark's SPX Mastery methodology, which relies on the Expected Daily Range (EDR) indicator, RSAi for rapid skew analysis, and our proprietary Adaptive Layered VIX Hedge known as ALVH. These tools ensure strikes are placed with mathematical precision rather than discretionary overlays. Adding a discretionary RSI oversold filter on the short put introduces subjective decision-making that deviates from our Set and Forget approach. RSI, defined as a momentum oscillator measuring the speed and magnitude of recent price changes on a scale of 0 to 100, can signal oversold conditions below 30. However, in the final 15 minutes of trading when our signals fire, such filters often lead to skipped trades on days when the EDR and RSAi still confirm valid setups. Our backtests show that applying this filter reduces the number of Conservative tier trades by approximately 25 to 30 percent annually while only marginally improving the win rate to around 92 percent. The net effect is lower overall income because the Theta Time Shift mechanism, which rolls threatened positions forward to 1-7 DTE on EDR greater than 0.94 percent or VIX above 16 then rolls back on VWAP pullbacks, already recovers 88 percent of losses without additional capital. Discretionary filters undermine the temporal martingale nature of our system and increase exposure to behavioral bias. The ALVH, with its 4/4/2 contract layering across 30, 110, and 220 DTE VIX calls at 0.50 delta, provides the true protection during volatility spikes, cutting drawdowns by 35 to 40 percent at an annual cost of only 1 to 2 percent of account value. We position size at a maximum of 10 percent of account balance per trade and avoid any stop losses, trusting the defined risk at entry and the Theta Time Shift for recovery. When VIX sits at its current level of 17.95, below the 5-day moving average of 18.58, our VIX Risk Scaling framework keeps all Conservative tier entries active provided EDR and RSAi gates are met. Introducing RSI filters on the short put risks turning a systematic edge into a discretionary process that underperforms the pure methodology over time. All trading involves substantial risk of loss and is not suitable for all investors.
