SEC Form 4 Insider Monitor — Transaction Alerts

Monitor recent SEC Form 4 insider transaction filings and receive alerts when new officer, director, or beneficial-owner activity appears. This Actor watches issuers, insiders, or transaction codes, snapshots seen filings, and emits only new transactions in delta mode.

What it does

On each run it pulls recent Form 4 filings using NexGenData's owned sec-form-4-insider-trading-scraper, explodes each filing into its individual insider transactions, labels each transaction code (purchase, sale, grant, option exercise, etc.), records what it has seen, and in delta mode emits only transactions that are new since the last run. It monitors recent filings on a rolling window — it is not a full real-time institutional feed, and it does not provide investment advice.

Who it's for

Equity research, investor relations, event-driven funds, governance and compliance teams tracking insider activity.

Recommended setup

Run once in full mode to baseline, then schedule daily delta runs. The first delta run per watch query records a baseline and emits nothing (expected); after that you get only new transactions.

Transaction labels

P→purchase, S→sale, A→grant / award, M→option exercise / conversion, D→disposition, F→tax withholding / payment, G→gift, J→other transaction; unknown codes are kept as unknown_code.

Outputs

accession_number, change_type, cik, ticker, company, insider_name, insider_role, is_director, is_officer, is_ten_percent_owner, transaction_date, transaction_code, transaction_label, security_title, shares, price, transaction_value, ownership_nature, filing_date, filing_url, matched_watch, detected_at (plus raw when enabled).

Delta mode vs full mode

• full — emits every matching transaction in the window and refreshes the snapshot.
• delta — emits only transactions whose (accession + insider + code + date) has not been seen before. First delta run baselines and emits nothing; later runs emit only new transactions.

Limitations

This is an alerting tool, not investment or legal advice. It monitors recent Form 4 filings on a rolling window via the owned source Actor; it is not a full real-time institutional coverage feed. Coverage and timing follow SEC EDGAR's publication of Form 4 filings. Always confirm against the official filing before acting.
