Insider Transactions API: Features

Finnworlds Insider Transactions API provides data on legal insider trading moves as reported to the SEC. Inside trades are reported to SEC via Form 3 (initial filing form that shows the stake in the company), Form 4 (form to disclose the trade of company stock within 2 days of the sale or buy), and Form 5 (form to declare earlier or deferred transactions). Insider transactions can be made by the company executives, directors, or individuals who own at least 10% of the shares of the company. For the insider transaction to be legal, it has to be reported to SEC with the relevant forms and the details of the traded security must be included.

The Insider Transactions API not only provides real-time data as SEC is reported but also stores this and grants access to complete historical insider transactions data based on past forms. The Historical Insider Transactions Database covers thousands of companies and as many transactions in the US.

A standard Insider Trade API output includes both general company and insider identification data, and the corresponding details on the insider transaction. Below is a breakdown of the items included in the insider transactions data.
