Why MAIN filings on EdgarKit beat the alternatives

Real-time, not batched. Yahoo Finance and most aggregators batch the SEC daily index. EdgarKit polls EDGAR every 30 seconds, so new MAIN filings appear here within a minute of SEC acceptance.
Developer-ready JSON. Whalewisdom and OpenInsider give you HTML tables you can read but not parse cleanly. Every transaction shown above is also available as structured JSON via the API.
Full transaction codes. Yahoo collapses Form 4 lines into 'Buy' / 'Sell'. We keep the raw transaction code (P, S, A, M, F, etc.) so you can filter compensation noise out of trading signal.
Footnote text preserved. Rule 10b5-1 plan references, indirect ownership disclosures, and gift transfers are all retained in the API response, not stripped.
Free tier covers it. 1,000 API calls/month, no credit card. Most ticker-specific workflows fit comfortably in free.

What insider trading data covers for MAIN

Main Street Capital Corporation (CIK 1396440) reports Section 16 insider transactions on Form 4 within two business days. Each filing carries the transaction date, transaction code (P for open-market purchase, S for sale, M for option exercise, F for tax withholding), shares, price, and post-transaction holdings. Optional footnotes disclose Rule 10b5-1 plan references and indirect ownership relationships.

How to interpret MAIN insider activity

Treat each filing line through three filters: the transaction code, the role of the filer (officer carries more signal than director), and the dollar value relative to the company's market cap. Open-market purchases (P) by C-suite officers carry the strongest bullish signal. Sales (S) referencing a Rule 10b5-1 plan in the footnotes are pre-arranged and should be discounted. See how to read a Form 4 for the full walkthrough.
