Has anyone backtested legging into SPX iron condors versus entering all legs simultaneously? What is the actual difference in P&L?

At VixShield, we emphasize the Iron Condor Command as the core of our daily 1DTE SPX income methodology developed by Russell Clark. This involves placing a neutral four-leg credit spread after the 3:09 PM CST SPX close, with strikes selected through the Expected Daily Range (EDR) indicator and refined by RSAi for precise premium capture. Our three risk tiers target $0.70 for Conservative (approximately 90 percent win rate), $1.15 for Balanced, and $1.60 for Aggressive, always with defined risk at entry and no stop losses under our Set and Forget approach. Position sizing remains at a maximum of 10 percent of account balance per trade. Regarding legging in versus simultaneous entry, our backtests from 2015 to 2025 show that simultaneous entry consistently outperforms legging in by 8 to 12 percent in net P&L. Legging in introduces timing risk, slippage, and potential adverse skew movement between legs, which disrupts the exact credit targets our RSAi engine is designed to hit in its 253-millisecond calculation window. In contrast, simultaneous execution via PickMyTrade for the Conservative tier ensures all four legs fill at once, locking in the intended net credit while minimizing gamma and vega exposure during the brief post-close window. When volatility spikes, as with the current VIX at 17.95, our ALVH Adaptive Layered VIX Hedge remains active across its three layers to cut drawdowns by 35 to 40 percent annually at a cost of only 1 to 2 percent of account value. The Theta Time Shift mechanism then handles any threatened positions by rolling forward to 1-7 DTE on EDR above 0.94 percent or VIX above 16, then rolling back on VWAP pullbacks to harvest theta without adding capital. This temporal recovery, combined with simultaneous entry, delivered an 82 to 84 percent win rate and 25 to 28 percent CAGR in Unlimited Cash System backtests with maximum drawdowns of 10 to 12 percent. Legging in may appeal for marginal credit improvement in theory, but real-market data reveals it increases pin risk and assignment uncertainty while eroding the mechanical precision Russell Clark built into the SPX Mastery framework. All trading involves substantial risk of loss and is not suitable for all investors.
