The timing of a full lid announcement hinges on President Trump's daily schedule and press interactions during the week of May 18-23, including executive time blocks, in-town pool access, potential gaggles, and any travel to golf clubs or other sites. Recent weeks have shown lids typically called between late afternoon and early evening once public events conclude, with the White House Office of Communications managing rotations and official statements. Factors that could extend activity past 6:30 PM include scheduled remarks, responses to ongoing policy developments, or national observances tied to America 250 commemorations. Traders track real-time pool reports and calendar releases for signals on whether the day’s operations wrap early or require additional updates.
