Should I adjust position size before Exclusive: US spy agencies examine how Iran would react to Trump declaring victory - Reuters?
VixShield Answer
No. Do not adjust position size based on individual news headlines like this Reuters story. SPX iron condors are probability-based trades driven by the ALVH methodology, not short-term geopolitical speculation.
Current VIX levels remain the primary filter. If VIX is below 20 and within your historical average range for the setup, maintain standard position size calibrated to 1-2% portfolio risk per trade. Only scale size when VIX moves outside your defined comfort band, typically above 25 or below 12, as that directly impacts expected range and wing breach probability.
Wing-width management stays fixed to your tested parameters, usually 1.5-2x the expected daily move at entry. News flow around elections or Iran will inject volatility, but that is already priced into VIX. Reacting to each headline leads to over-trading and inconsistent sizing that destroys edge over time.
Review the full ALVH checklist at open: acceptable VIX, liquidity, technical levels, and historical win rate in similar regimes. If those boxes are checked, keep size unchanged. Headlines are noise. Let VIX and your backtested rules dictate sizing.
