# Where the data comes from

Your own records, official filings and market data — what each feature reads, how fresh it is, and what it covers.

Source: https://360marketview.com/docs/reference/data-sources/

360marketview shows three kinds of data. **Your records** — the trades and cash you enter or import — are the only source of your own figures. **Official public filings** are read straight from the government sources that publish them. **Market data** — prices, company details, analyst ratings, calendars — comes from established market-data providers.

## Coverage

US-listed **stocks and ETFs**: Nasdaq, NYSE, NYSE American, NYSE Arca, Cboe BZX and IEX, from Nasdaq’s official symbol directory, refreshed every night. No crypto or bonds.

## Things worth knowing

- **Prices can be delayed.** When the price source can’t be reached, the last price from the past day is shown and marked **Prices delayed** rather than nothing.
- **Congress trades are weeks old.** Members must report each trade within 45 days, so a trade appears when its report is filed. Amounts are the ranges the reports give, not exact figures. The Senate isn’t covered yet.
- **Insider buying and selling** means trades on the open market (Form 4 codes P and S). Grants, option exercises, shares withheld for tax and gifts are listed but not counted as buying or selling.
- **A multiple that can’t be calculated honestly isn’t shown.** A company that lost money has no P/E, not a huge one; the page says why.
- **Index lines** are price returns, without dividends.

360marketview shows information for your own research. It doesn’t tell you what to buy or sell, and it can’t place a trade.
