How should traders adjust Iron Condor position size or strike selection when the VIX is around 18? Is the Conservative tier the only appropriate choice, or is the Balanced tier still viable?

When the VIX sits near 18, as it does today at 17.95 with its five-day moving average at 18.58, position sizing and strike selection for 1DTE SPX Iron Condors require disciplined application of VIX Risk Scaling rules from Russell Clark's SPX Mastery methodology. At this level, which falls in the 15-20 range, Aggressive tier trades are blocked while both Conservative and Balanced remain available. The Conservative tier, targeting a 0.70 credit, maintains its approximately 90 percent win rate across roughly 18 out of 20 trading days by placing wider strikes guided by the EDR indicator and RSAi. The Balanced tier, aiming for a 1.15 credit, stays executable but demands stricter adherence to current contango signals and lower overall position sizing. Position sizing remains capped at a maximum of 10 percent of account balance per trade regardless of tier. With SPX closing recently near 7138.80, the Expected Daily Range formula blends short-term VIX9D and 20-day historical volatility to recommend precise strikes that match the premium target without chasing excessive credit. RSAi then refines these in real time by analyzing skew, VWAP positioning, and four-hour VIX momentum, adjusting wings in five-dollar increments until the exact credit is achieved in under 253 milliseconds. This prevents the common error of forcing Balanced credits when market conditions favor more conservative wings. The ALVH hedge stays fully layered across short, medium, and long VIX calls in a four-four-two contract ratio per ten Iron Condor units, cutting potential drawdowns by 35 to 40 percent at an annual cost of only one to two percent of account value. Because the strategy is strictly Set and Forget with no stop losses, the Theta Time Shift mechanism provides zero-loss recovery by rolling threatened positions forward to one-to-seven DTE on EDR above 0.94 percent or VIX above 16, then rolling back on VWAP pullbacks below that threshold. At VIX 17.95 the system remains in a workable regime that favors premium collection, yet prudence suggests many traders default to Conservative to preserve capital until VIX drops below 15 and all three tiers reopen. This approach aligns with the Unlimited Cash System's goal of winning nearly every day or at minimum not losing. All trading involves substantial risk of loss and is not suitable for all investors.
