How it works
From the official filing to your pocket, in three steps.
No guesses, no rumours. Only the document the investor filed under their own signature.
01
The investor files with the SEC
In the US, when a company executive or a holder of more than 10% buys or sells shares, they must disclose it on Form 4 within two business days. Large funds disclose their entire portfolio every quarter on Form 13F.

You get a plain table
Who, which stock, which day, how many shares, at what price. If the stock is in your watchlist, you also get a notification. The decision is still yours; we only make the data readable.

No. TradingScope organises and displays public data; it does not recommend buying or selling any stock. Decisions are yours alone.
Trade data comes from the US Securities and Exchange Commission's EDGAR system; Form 4 and 13F filings are read directly from there. Prices and news come from licensed providers and may be delayed.
Form 4 trades must legally be filed within two business days; the app scans filings every 30 minutes. 13F portfolio disclosures arrive up to 45 days after quarter end, which is why the answer to "when did they buy" is in Form 4.
Currently free, with no ads and no data selling. If a paid tier is ever introduced, it will be announced without restricting existing features.
