The value is in what we do not call a signal.
The SEC XML stores every transaction. Raspberry keeps that evidence, reads the footnotes and separates voluntary open-market activity from vesting, option exercises, gifts, tax withholding, stock purchase and dividend reinvestment plans and pre-programmed 10b5-1 trades.

Represents the number of shares required to be sold by the Reporting Person to cover the tax withholding obligation in connection with the settlement of vested restricted stock units. This sale is mandated by the Issuer's election under its equity incentive plans to require the Reporting Person to fund this tax withholding obligation by completing a "sell to cover" transaction with a brokerage firm designated by the Issuer. This sale does not represent a discretionary trade by the Reporting Person. The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $48.40 - $48.78, inclusive. The Reporting Person undertakes to provide to the Issuer, any security holder of the Issuer, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the range set forth in this footnote to this Form 4.
Raspberry interpretation
Informational — no alert
Reason: tax_withholding. The filing footnotes identify tax withholding. The trade is reported under a Rule 10b5-1 plan.

Voluntary purchases and sales; administrative noise stays hidden.
