Weren't you having an issue with other sites going down? @Sentdex

you say tomato, i say... alphavantager. It helps with JSON too which will take a little more code. 😉

like the call to fread(). is there a speed improvement over read_csv? will become important in scaling to multiple equities.

Thanks that's what I thought. Will do some microbenchmarking since output needs to be tibble.

Data.table seems to be the preference for performance. I'm tidyverse all the way bc of readability & intuitive syntax. Both have merit.

Wow! 50 to 12 sec on 4 cores. Impressive and likely faster in 8 and so on.

How come your Sys.time() shows nanoseconds?
