Are Alpaca Historical Tick Data Point-In-Time?

If I use the historical data API to fetch historical SIP trades and quotes, can I assume the data are “point-in-time”, defined as

  1. data are NOT adjusted for subsequent corporate actions (e.g. splits, divs, spin-offs)
  2. data are fetched under the ticker symbol at the time (even if there should be a subsequent symbol change)
  3. data can be fetched for stocks that were subsequently delisted or acquired?

You can find out all about Alpaca’s historical data API here..

I have seen a few cases where data for delisted stocks were not fetched.

Hey :wave:

Actually the question to all 3 of your questions is yes. Trades & quotes are not adjusted, symbol renames are not followed and the delisted symbols remain in the database.
