Should I adjust position size before Three dead in fire at shopping centre west of Tehran, Iranian media says - Reuters?
VixShield Answer
No. Do not adjust your SPX iron condor position size based on this news event. It is unrelated to VIX levels, market volatility regime, or the technical setup of your trade.
Stick strictly to the ALVH methodology. Size is determined before entry by your defined risk per trade, account percentage rules, and current VIX environment. Once the iron condor is on, position size remains fixed unless you hit a pre-set wing-width adjustment trigger or your portfolio-level risk limits.
News-driven geopolitical headlines can spike VIX temporarily, but they rarely change the core volatility structure that governs iron condor probability. Monitor the VIX term structure and your short strikes relative to support levels instead. If VIX jumps materially, focus on whether your short deltas have moved beyond your adjustment threshold, not on the headline itself.
Keep position size consistent with your plan. Reacting to random news leads to over-trading and inconsistent results. Trade the iron condor mechanics, not the newspaper.
