• 13F changes — mode: 13fDiff with managerCiks (e.g. Berkshire 1067983) after each quarter's filing deadline.

FAQ

How fresh is the data?
latest mode reads SEC's current-filings feed, so new Form 4s show up minutes after EDGAR publishes them. Schedule hourly or daily.

Why is userAgent required?
SEC fair-access policy requires automated clients to declare a name and contact email. Use your own.

What do transaction codes mean?
P = open-market purchase, S = sale, A = grant/award, M = option exercise, F = tax withholding, G = gift. Most buy signals use P only.

Is this investment advice?
No. It is a data tool; always check the linked original filing.
