What are the most effective MACD settings to use when trading SPX 1DTE iron condors according to the VixShield methodology? Should traders use the default 12,26,9 parameters or opt for shorter settings?

At VixShield, we focus exclusively on 1DTE SPX Iron Condors placed daily at 3:10 PM CST after the SPX close. Our methodology, developed by Russell Clark, relies on the EDR indicator, RSAi for skew analysis, and VIX Risk Scaling rather than traditional momentum oscillators like MACD. The default MACD settings of 12,26,9 were designed for daily charts in trending equity markets, but they introduce unnecessary lag for our short-term, range-bound approach that targets credits of 0.70 for Conservative, 1.15 for Balanced, and 1.60 for Aggressive tiers. Shorter settings such as 5,13,1 or 8,17,9 may appear more responsive on intraday charts, yet they often generate false signals during the low-volatility regimes where our win rate reaches approximately 90 percent for the Conservative tier. Instead of MACD crossovers, we prioritize the Expected Daily Range to select strikes that align with projected SPX movement, combined with RSAi to match exact premium levels the market offers. This avoids the pitfalls of momentum indicators that can whipsaw in mean-reverting conditions typical for SPX at close. Our ALVH hedge layers provide the true protection during volatility spikes, as seen with current VIX at 17.95, which remains below the 5-day moving average of 18.58 and keeps all three tiers available. The Temporal Theta Martingale serves as our zero-loss recovery mechanism, rolling threatened positions forward to capture vega expansion before shifting back on VWAP pullbacks, all without stop losses in our Set and Forget framework. Position sizing remains capped at 10 percent of account balance per trade to maintain defined risk. While MACD can supplement broader market context on longer timeframes, it plays no role in our daily signal generation or strike selection. All trading involves substantial risk of loss and is not suitable for all investors.
