Nine tabs, one site
The tabs a trader keeps open, and the page here that answers each one. Who we read it from and how old the answer can be come from our sources register, word for word.
| The tab | Here | Read from | How old it can be |
|---|---|---|---|
| A chart Where did it close, and how has it traded? | Charts | Databento | End of day, never intraday. |
| A screener Which companies pass my filters? | Screener | US Securities and Exchange Commission, Databento | Each figure is as of the filing it comes from. |
| Insider trades Who inside the company bought or sold? | Insider trades | US Securities and Exchange Commission | Form 4 is due within two business days of the trade. Our scheduled jobs run every 6 hours on top of that. |
| Fund holdings What do the big funds hold? | Fund holdings (13F) | US Securities and Exchange Commission | Form 13F is due within 45 days after each quarter ends, so a fund's holdings can be four and a half months old by the time its next filing lands. |
| Short interest How much of it is sold short? | Short interest | FINRA | Short positions as of the 15th and the last business day of each month. FINRA publishes each set about seven business days later, so the newest figures are 9 to 26 days old. |
| An options chain Where is max pain for this expiry? | Max pain | Cboe Global Markets | Cboe's delayed quotes, about 15 minutes behind the market, plus our cache. |
| Filing search Which filings mention this? | Filing search | US Securities and Exchange Commission | EDGAR indexes a filing for search after accepting it. |
| An earnings calendar When does it report? | Earnings calendar | US Securities and Exchange Commission | A filing is public the moment EDGAR accepts it. |
| A news feed What has been written about it today? | Headlines | TickerTick | Headlines as the outlets publish them, plus up to 15 minutes of cache. |
