Just to confirm my understanding, which of the following are correct?
1) Intraday data is in format MSFT.t6. StartDate is defined as 2022. Therefore, the first bar is at the very beginning of 2022 and will be within the lookback period (if there is lookback).
2) Intraday data is in format MSFT_YYYY.t6 and includes 2020, 2021, and 2022. StartDate is defined as 2022. Therefore, the first bar is at the very beginning of 2022 and will be within the lookback period (if there is lookback).
3) Daily data is in format MSFT.t6. StartDate is defined as 2022. Therefore, the first bar is at the very beginning of 2022 and will be within the lookback period (if there is lookback).
