Legend
Everything on the site comes from SEC Forms 4 and 4/A, the reports company insiders must file within two business days of trading their own company's stock.
Row colors

| Red | Open-market sale (code S). |
| Yellow | Sale after option exercise (S - Sale+OE): the same filing reports an option exercise (code M or X) and a sale, so the shares sold were typically just acquired by exercising options. |
| None | Everything else: grants, tax withholding, gifts, exercises without a sale, and so on. |
Columns
| X | Flags for the filing. D derivative transaction in the filing (usually an option exercise).

Cluster buys
A cluster is two or more distinct insiders buying the same company's stock on the open market within a rolling two-week window. Several insiders committing their own money at once is one of the stronger signals in insider data, which is why it gets its own list.
Aggregation
A filing often reports many small trades. Lists show one row per insider, transaction code and security table (common stock or derivatives) per filing, with quantities summed and price volume-weighted, the same convention openinsider uses. The filing page shows every underlying transaction.
