How do traders size positions when trading SPX 1DTE iron condors while following the 10 percent account risk rule from Russell Clark?

At VixShield we trade SPX 1DTE iron condors exclusively using the Iron Condor Command placed daily at 3:10 PM CST after the SPX close. This Set and Forget methodology relies on the Expected Daily Range indicator, RSAi for rapid 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 18 out of 20 trading days in extensive backtests. Position sizing follows Russell Clark's strict 10 percent account risk rule to ensure no single trade can threaten more than that portion of total capital. For a $100,000 account this means defining maximum risk at $10,000 per trade. Because SPX iron condors are defined-risk we calculate the width between the short and long strikes minus the credit received to determine the actual dollar risk per contract. If a Conservative tier iron condor has a $5.00 wide spread and we collect $0.70 credit the risk per contract equals $430. We then divide the $10,000 account risk budget by $430 to arrive at roughly 23 contracts. This keeps us inside the 10 percent limit even on a full breach. The ALVH Adaptive Layered VIX Hedge runs in parallel with a 4/4/2 contract ratio across short, medium, and long VIX calls to cut drawdowns by 35 to 40 percent during volatility spikes. When VIX sits at the current level of 17.95 we remain in the Balanced and Conservative tiers only while keeping all three ALVH layers active. The Theta Time Shift mechanism allows any threatened position to roll forward to 1-7 DTE on an EDR reading above 0.94 percent or VIX above 16 then roll back on a VWAP pullback capturing additional premium without adding capital. This temporal recovery has turned 88 percent of historical losses into net gains across 2015-2025 backtests. We never use stop losses. Instead we trust the probabilistic edge of daily theta decay inside the EDR-defined range. Proper sizing combined with ALVH protection and Theta Time Shift creates the foundation of our Unlimited Cash System designed to win nearly every day or at minimum not lose. All trading involves substantial risk of loss and is not suitable for all investors.
