running the same report but on different data ranges give me different results.
from february 2019 onward I get the expected results (see second snapshot), with all the columns like bid price and ask price filled.
before february 2019 I get a duplicated line (which is annoying but not problematic), but I also don't see anymore the bid and ask information (See first snapshot). Do I have to modify my query? Are those fields not available historically before 2019?
