Should I adjust position size before Ivey PMI s.a?

Before the Ivey PMI release, reduce your position size by 30-50 percent. This event often triggers sharp SPX moves that can breach iron condor wings within minutes, especially when VIX sits above 15.

Under the ALVH methodology, you only carry full size when implied volatility rank is low and no high-impact data sits inside your 0-5 DTE window. Ivey PMI qualifies as a tier-1 Canadian macro release that reliably spikes VIX and widens SPX bid-ask spreads, so it violates the “avoid large events” rule.

If your current iron condor has 45-50 point wings, cutting size now protects margin and gives you dry powder to roll or defend after the print. Rebuild to full size only once the data is digested and VIX settles. Never add size into the release. Trade smaller, stay mechanical, and let the post-event volatility contraction work in your favor instead of fighting it.
