Should I adjust position size before Economic & event calendar in Asia, May 1, 2026 - Japan (tokyo) inflation, China holiday?

Yes adjust your position size downward before the May 1 2026 Asia event window. Tokyo CPI and the China Golden Week holiday create cross-border liquidity gaps that routinely widen SPX overnight ranges and elevate VIX 1-2 points even on light US volume.

Under ALVH methodology cut your normal notional by 30-40 percent when VIX is 16 or higher and any major Asian inflation print lands inside your iron condor’s first 36 hours. This preserves margin headroom for the volatility spike without forcing early wing adjustments.

Keep wing width at 25-30 points on the SPX condor you do carry. Tighter wings become too vulnerable to the gap risk created by thin Asian liquidity. Enter the reduced size after the Tokyo print clears rather than before the close on April 30.

If VIX is already above 18 skip the trade entirely and wait for the post-holiday stabilization on May 2. Smaller size plus wider wings plus strict VIX filter keeps the condor inside ALVH risk parameters through the holiday-distorted session.
