insider.transactions

Insider (SEC Form 4) transactions — open-market buys/sells, awards, option exercises — for a company (by ticker) or a person (by insider name). Pass `signal: true` to restrict to open-market buys/sells (codes P/S), the tradeable subset. Pass `since` to diff only new filings. A ticker names ONE issuer: the SEC CIK with the newest Form 4 under that symbol, read across every symbol that issuer has filed with (filers type the symbol, and symbols get reused); `issuer_resolution` says which issuer answered and whose rows under the symbol were left out. Pass `issuer_cik` to read a specific issuer instead. Cost: 1 credit per call.
