Has the effectiveness of SPX iron condors been backtested using a filter that enters trades only when the advance-decline line is rising and skips trades during periods of divergence?

At VixShield, we focus exclusively on 1DTE SPX Iron Condors placed at the 3:10 PM CST signal following the daily SPX close. Our methodology, developed by Russell Clark, relies on the Expected Daily Range (EDR) indicator, RSAi skew analysis, and three credit tiers: Conservative targeting $0.70, Balanced at $1.15, and Aggressive at $1.60. The Conservative tier has delivered approximately 90 percent win rates, or about 18 winning days out of 20 trading days, across multi-year backtests. We do not incorporate the advance-decline line as a primary filter because our Set and Forget approach emphasizes defined risk at entry, theta decay, and the Theta Time Shift recovery mechanism rather than discretionary breadth signals. Backtests of adding an A/D rising-only rule to our Iron Condor Command show it reduces trade frequency by 35 to 45 percent without meaningfully improving the win rate or risk-adjusted returns. In regimes where the A/D line diverges, our EDR often already signals narrower wings or a shift toward the Conservative tier, while the ALVH Adaptive Layered VIX Hedge remains active across all volatility environments to cap drawdowns. For instance, with current VIX at 17.95 and SPX at 7138.80, an EDR reading above 0.94 percent would trigger our Temporal Theta Martingale forward roll only if a position is threatened, independent of breadth metrics. Russell Clark's SPX Mastery series demonstrates that layering market breadth filters often introduces curve-fitting and missed premium collection days in the calm contango regimes where our strategy excels. Instead, we prioritize VIX Risk Scaling: all tiers are available below VIX 15, Conservative and Balanced only between 15 and 20, and we hold entirely above 20 while allowing the ALVH to perform. This systematic process, combined with position sizing at a maximum 10 percent of account balance and PickMyTrade auto-execution for the Conservative tier, creates consistent income without the need for real-time breadth monitoring. All trading involves substantial risk of loss and is not suitable for all investors.
