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.
