Splits, dividends and ticker changes
The adjusted data already accounts for every event below, so there is nothing left for you to fix.
Splits 0
No splits or reverse splits in the data period (2024-05-10 to today).
Dividends 0
No cash dividends in the data period, so the adjustment covers splits only.
Ticker changes 0
Traded as OKLO throughout the data period, so there is nothing to stitch.
Year by year
Computed from adjusted daily bars. The table also lists estimated 1-minute rows per year, to help size a download.
OKLO data FAQ
Do you have overnight (20:00–4:00 ET) data?
Not yet. The data comes from the consolidated tape (SIP), which covers 4:00–20:00 ET. US exchanges plan to add overnight trading to the SIP from 2026-12-06, and we will follow.
Can I keep the download up to date with the API?
Yes. Downloads and the market data API share the same data and the same adjustment. Download the history once, then pull each new day from the /v2/aggs endpoint.
