No span in this chart meets either cluster rule, so nothing is shaded.
Unofficial daily closes (Yahoo), split-adjusted. Trades sit on their trade date: members disclose up to 45 days later and insiders within two business days, so the public could not have acted on a trade on the day it is drawn. A price move after a shaded cluster is not evidence that anyone knew anything — clusters are picked out after the fact, and hindsight makes any pattern look meaningful.
Congressional marks are sized by the bracket floor — the least the disclosed range allows, never the amount traded. Insider marks are sized by shares × reported price; a row with no price, or an as-filed value too large to be real, gets the smallest mark. The two populations share the time axis only: their trades are never counted together.
Shaded spans apply each population’s own cluster rule over a window ending on every trade date, as if every trade had already been disclosed. Members: at least 3 members, each with at least $15k in bracket floors, and an estimated $500k or more (sum of bracket midpoints) in one direction within 90 days, stocks, funds and options only — the cluster alert’s rule. Insiders: at least 3 distinct primary filers in one direction within 30 days.
A trade dated on a weekend or market holiday is drawn on its own date, between the sessions around it; its readout gives the closes on either side. 1 trade is dated far before the rest or after today (a filing typo) and is not drawn here. Every trade is also listed below.
Each mark is one trade, placed on the trade date the filing printed; marks stack where trades collide. Size is the bracket floor — the least the disclosed range allows — not the amount traded. Select a mark to open the member.
The band is the full range these disclosures permit; the tick is the midpoint estimate. Members report brackets, so the true figure lies somewhere in the band.
