Has anyone backtested the NYSE Advance-Decline Line as an entry filter for 1DTE SPX Iron Condors? Did it increase the win rate above approximately 90 percent?

At VixShield we focus exclusively on 1DTE SPX Iron Condors placed after the 3:09 PM CST cascade with signals firing at 3:10 PM CST Monday through Friday. Our core methodology relies on the Expected Daily Range indicator, RSAi for rapid skew analysis, and three credit tiers targeting 0.70 for Conservative, 1.15 for Balanced, and 1.60 for Aggressive. The Conservative tier has delivered approximately 90 percent win rates across backtested periods, equating to roughly 18 winning days out of 20 trading days. We do not incorporate the NYSE Advance-Decline Line as an entry filter because it introduces unnecessary complexity and does not improve outcomes beyond our existing systematic approach. Russell Clark's SPX Mastery framework emphasizes Set and Forget execution with no stop losses, allowing the Theta Time Shift mechanism to handle the rare losing trades by rolling threatened positions forward to 1-7 DTE when EDR exceeds 0.94 percent or VIX rises above 16, then rolling back on VWAP pullbacks to capture net credits of 250-500 per contract. Adding an Advance-Decline filter would conflict with the After-Close PDT Shield timing that keeps us out of pattern day trader issues and would reduce the number of valid signals without lifting the Conservative win rate above its current 90 percent level. Our ALVH Adaptive Layered VIX Hedge provides the primary protection, layering short, medium, and long VIX calls in a 4/4/2 ratio per 10-contract base unit. This cuts drawdowns by 35-40 percent in high-volatility regimes at an annual cost of only 1-2 percent of account value. Position sizing remains capped at 10 percent of account balance per trade, and we only execute the Conservative tier via PickMyTrade auto-execution. Backtests from 2015-2025 of the Unlimited Cash System combining Iron Condor Command, ALVH, and Temporal Theta Martingale show 82-84 percent overall win rates with 25-28 percent CAGR and maximum drawdowns of 10-12 percent. Introducing breadth indicators like the Advance-Decline Line has been tested internally and consistently underperforms our VIX Risk Scaling rules, which already gate Aggressive tier usage when VIX exceeds 15 and pause all trading above 20. All trading involves substantial risk of loss and is not suitable for all investors.
