How do you determine position sizing and establish risk rules when trading 1DTE SPX iron condors across full market cycles?

At VixShield, we approach position sizing and risk rules for our 1DTE SPX Iron Condor Command with a disciplined framework rooted in Russell Clark's SPX Mastery methodology. Our core rule is to never allocate more than 10 percent of total account balance to any single trade. This keeps drawdowns manageable even during periods of elevated volatility. For a $100,000 account, that means a maximum notional risk of $10,000 per trade, typically achieved by trading between 5 and 20 contracts depending on the credit received and chosen tier. We offer three risk tiers that fire daily at 3:10 PM CST after the SPX close: Conservative targeting $0.70 credit with an approximate 90 percent win rate, Balanced at $1.15 credit, and Aggressive at $1.60 credit. Strike selection relies on our proprietary EDR (Expected Daily Range) indicator combined with RSAi (Rapid Skew AI) to optimize wings that match current market willingness to pay the target premium. This ensures we stay within the statistically probable range on most days. Risk management follows our Set and Forget philosophy with no stop losses and no active intraday adjustments. Defined risk is established at entry, and we rely on the Theta Time Shift mechanism to recover from the roughly 10 percent of trades that move against us. When EDR exceeds 0.94 percent or VIX rises above 16, the Temporal Theta Martingale rolls threatened positions forward to 1-7 DTE to capture vega expansion, then rolls them back on a VWAP pullback when conditions calm. Our ALVH (Adaptive Layered VIX Hedge) provides the ultimate backstop, layering VIX calls across short, medium, and long timeframes in a 4/4/2 ratio per 10 Iron Condor contracts. This hedge reduces portfolio drawdowns by 35-40 percent during spikes at an annual cost of only 1-2 percent of account value. VIX Risk Scaling further refines exposure: below 15 we deploy all tiers, 15-20 limits us to Conservative and Balanced, and above 20 we hold entirely while allowing ALVH to work. Through full market cycles this combination has delivered backtested win rates of 82-84 percent, a 25-28 percent CAGR, and maximum drawdowns of 10-12 percent with an 88 percent recovery rate on losing positions. All trading involves substantial risk of loss and is not suitable for all investors.
