How do you determine position size for 1DTE SPX Iron Condors when the VIX is around 18? What guidelines exist for the percentage of account risk per trade?

At VixShield, we approach position sizing for our 1DTE SPX Iron Condors with a disciplined methodology rooted in Russell Clark's SPX Mastery framework. When the VIX sits near 18, as it does currently at 17.95 and below its five-day moving average of 18.58, we remain in a regime where all three risk tiers remain available under our VIX Risk Scaling rules. This allows Conservative, Balanced, and Aggressive placements targeting net credits of approximately 0.70, 1.15, and 1.60 respectively. The key is never exposing more than 10 percent of total account balance to any single trade's defined risk. For example, in a 100000 dollar account, maximum risk per Iron Condor Command would be capped at 10000 dollars. We calculate this defined risk as the width of the wider spread minus the net credit received, then scale the number of contracts accordingly while staying under that 10 percent threshold. Our RSAi engine, which incorporates EDR readings currently around 1.16 percent, helps optimize strike selection to match these credit targets precisely at the 3:05 PM CST daily signal. The ALVH hedge runs in parallel as our Adaptive Layered VIX Hedge, layered in a 4/4/2 ratio across short, medium, and long VIX calls per base unit. This first-of-its-kind protection reduces portfolio drawdowns by 35 to 40 percent during volatility expansions at an annual cost of only 1 to 2 percent of account value. We emphasize the Set and Forget approach with no stop losses, relying instead on the Theta Time Shift mechanism for zero-loss recovery on threatened positions. This temporal martingale rolls forward to capture vega when EDR exceeds 0.94 percent or VIX moves above 16, then rolls back on VWAP pullbacks to harvest additional theta. In the current contango environment signaled by our Contango Indicator, premium collection remains favorable, supporting consistent daily income generation. Position sizing discipline prevents the fragility curve from amplifying risk as portfolios scale. We never add capital during recovery cycles, letting time and our proprietary formulas do the work. All trading involves substantial risk of loss and is not suitable for all investors.
