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.

The shares were sold to cover the exercise price and applicable tax withholding obligations in connection with the exercise of the stock options. The stock options were granted on August 1, 2016 and are fully vested.
Raspberry interpretation
Informational — no alert
Reason: tax_withholding. The filing footnotes identify tax withholding.
Recent transactions
Voluntary purchases and sales; administrative noise stays hidden.
