When looking at the linked archives [1] it seems that they sit at around 4GB/day. Is that really all of the data that the US stock market generates a day? I thought it would be at least 10x that. [1] https://iextrading.com/trading/market-data/

#53One file has a size of nearly 5 GB... Every day two of these files get released... So nearly 10 GB every day. So if we download the raw data every day for one year, we would have 3650 GB just for one year... It would be interesting how much reduced the size of the processed data is compared to the raw data. You say that you have 50 GB of data spanning multiple years. How many years exactly?

For anyone who wants the naming backstory, InvestorsExchange.jl was originally IEXTools.jl, but Julia's package registration automatic name checks didn't like it ("Name does not meet all of the following: starts with an uppercase letter, ASCII alphanumerics only, not all letters are uppercase. Name is not at least five characters long") [1]. So to Wikipedia I went to find the non-acronym name of the IEX exchange, which is "Investors Exchange" [2]. Thank you all for helping me understand why IEX goes by IEX in all of their branding.

#57Earlier quoted context omitted.
I too am here for this reason also. I would change the name. It is an issue. Put a dash in it or an underscore... just something.
Underscore is (was?) illegal in domain names.
However, for host names or for a URL's host component, you're limited to hyphens.
In this case though it's just the name of a Julia package[1], which isn't bound by either the rules of domain names or host names as .jl is not a TLD.

Domain names of the old internet: - penisland.net (sells pens) - expertsexchange.com (renamed to experts-exchange.com) - therapistfinder.com (find a therapist) - whorepresents.com
My employer did some work early in Dotcom for a company that owned the domain name "manufacturersexchange", when I pointed out that was a terrible name for a business they said "no business person would notice that". Business never got off the ground.

#59It's good that the actual file is InvestorsExchange.jl, because without the E capitalized, that's definitely not how my brain parses it.
