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. 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. 2 trades past the stack height are counted as “+N” at the end of their column rather than drawn. 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.
