How to read this signal
Only open-market P purchases and S sales count toward the signal. Vesting, options, taxes and gifts remain in the source data but do not trigger alerts. Rule 10b5-1 trades are shown as informational.

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.

These shares were sold to cover tax withholding due upon vesting of previously granted restricted stock units ("RSUs"). Such "sale to cover" was automatically effected to satisfy tax withholding obligations and does not represent a discretionary trade by the Reporting Person. The price reported in Column 4 is a weighted average price of all shares sold on the transaction date by the Issuer's broker to cover taxes upon the vesting of RSUs for certain employees of the Issuer, including the Reporting Person. These shares were sold in multiple transactions at prices ranging from $0.783 to $0.825, 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.
Raspberry interpretation
Informational — no alert
Reason: tax_withholding. The filing footnotes identify tax withholding.
Recent transactions
Voluntary purchases and sales; administrative noise stays hidden.
