insider.company

Net insider activity for one company over a window: open-market buy vs sell value/shares and distinct buyer/seller counts. Answers 'are insiders net buying or selling this name right now?' The ticker resolves to ONE issuer, the SEC CIK with the newest Form 4 under that symbol, and the window covers every filing by that issuer whatever symbol the filer typed; `issuer_resolution` names it and any other issuer whose rows share the symbol. Pass `issuer_cik` to pin a specific issuer. Cost: 3 credits per call.
