How teams use it

  1. Read the day. Pick a session on the chart; the announcement, posts and headlines of that day sit beside it with the return and the volume against normal.
  2. Compare with peers. The same window for your company and the peers you actually get compared to, row by row, every cell naming what it counted.
  3. Prove it. Every observation is a rule with its evidence attached. Paste the link into the pack; the reader can check every line at the source.

What we refuse to do

  • No scores, no sentiment. Counts, returns and timing you can recompute; nothing a model made up.
  • No cause. “Shares closed up 4% that session” is what we say; why is your call.
  • No silent gaps. Data we do not hold is stated as such, never shown as a zero.
  • No unnamed sources. Exchange, regulator, the platform’s API, the press archive: each item links to where it came from.
