    Did you read the thread?
  5. yes sir, but not much info
  6. You seem to be asking for two things:
    (1) level of data quality?
    (2) how far back in history is it available?
    To answer the first one you'll need a reference in order to determine whether there are deviations or mistakes. What reference do you want to compare the IB historical data to?
    To answer the second one: I guess that the available history depends on the instrument/stock. Tesla does not have a stock price history as long as Ford. If you want to download 1 minute data you'll not be able to to download the entire history in one run. You'll probably have to split it up in multiple runs, each for a different period.
