DATASTREAM IS NOT PERFECT
▸ Datastream has a nice interface
when looking at data, but a bad
one when fetching data with excel.
▸ It is extremely slow when fetching
large amount of data.
▸ Slow is fine, but sometimes it
crashes for fetching too many data.

DATASTREAM IS NOT PERFECT
▸ If I want all stock data from
NASDAQ listing, I can’t select all
symbols, because symbol strings
are too long, it exceeds excel’s limit.
▸ Even if I create my own token for
the list of symbol, Datastream
fetches all data at once, filling up
the entire RAM, causing the
computer to crash.
▸ Slow is fine, but crash is not
acceptable.
