Should I adjust position size before Gold slips as Iran risks support dollar, keep inflation fears in focus - Reuters?

No. Do not adjust position size based on this headline. SPX iron condors are probability-based trades driven by implied volatility, not geopolitical speculation or dollar strength narratives. Reuters stories like this create short-term noise that frequently reverses within days and has poor predictive value for index path.

Current VIX level remains your primary filter under the ALVH methodology. If VIX is below 20 and the setup meets your defined edge criteria, keep position size consistent. If VIX has already climbed above 22-23 on these tensions, reduce size or stand aside until the spike decays. That is the correct risk adjustment, not reacting to the news itself.

Maintain fixed wing-width rules regardless of headlines. Use 1.5-2.0 times the expected daily move for your short strikes and keep the full spread width at least 40-50 points on SPX to preserve positive theta and limit gamma exposure. Scaling size on macro fear headlines violates the systematic approach and turns a mechanical strategy into discretionary guessing.

Trade the volatility regime, not the news flow. Review your ALVH levels and wing width first, then decide size.
