- Bar timestamp
- Each bar is stamped with the START of its interval — the 09:30:00 one-minute bar covers 09:30:00–09:30:59.
- Sessions
- Pre-market 04:00–09:30, regular 09:30–16:00, after-hours 16:00–20:00 (Eastern). Half-day sessions close the regular session at 13:00.
- Gaps
- A bar is written only when at least one trade printed in that interval; minutes without trades are omitted, never forward-filled. Expect fewer than 960 one-minute bars per day for most tickers.
- 5-minute and hourly bars
- Built from the 1-minute bars (open = first open, high = max high, low = min low, close = last close, volume = sum); clock-aligned bins (09:30, 09:35 … / 09:00, 10:00 …) stamped with the bin start; the 09:00 hourly bar therefore contains 09:00–09:29 pre-market plus the first 30 regular-session minutes.
- Files
- Plain CSV, comma separated, one header row, UTF-8,
"\n"line endings; each zip also contains README.txt and {SYMBOL}_corporate_actions.csv (date,type,value).
How adjustment works
Unadjusted files hold prices and volume exactly as traded. Adjusted files are back-adjusted for splits and cash dividends:
- Split ratio r with ex-date D: prices before D ÷ r, volume before D × r.
- Cash dividend d with ex-date D: prices before D ×
1 - d / C, where C is the regular-session close of the session before D. - Factors compound backwards in time, so adjusted history changes whenever a new split or dividend goes ex. Dividend amounts in the corporate actions file are as declared (not split-adjusted).
Dividend $0.27, prior close $313.30 → factor 1 − 0.27 / 313.30 = 0.999138; a $285.52 bar before the ex-date becomes $285.27.
