How this service works
Insider buy/sell transactions from Form 3/4/5, SEDI and company filings (US, UK, CA, AU, IN and major EU markets). Max 100 transactions per call.
Output
Returns an array of insider transaction records for the specified stock symbol, each including the insider's name, share count, change in shares, filing date, transaction code (e.g. 'S' for sale), transaction date, and transaction price, along with the stock symbol.
Example use cases
Track CEO stock sales signals
“Show me all the insider sell transactions for Tesla over the last three months. I want to know if the executives are dumping shares, which might signal something about the company's outlook.”
Monitor director buying activity
“Pull the insider trading data for Microsoft from the past six months. I'm specifically interested in any buys — when directors or officers are actually putting their own money in, it's usually a good sign.”
Check recent SEC filings for company
“Can you get me the insider transactions for NVIDIA that were filed in the last month? I need to see the transaction dates, share counts, and who made the trades to understand if there's any unusual activity.”
