[R-SIG-Finance] Interaction with Alpha Vantage?

[Duncan Murdoch]

The quantmod package added support for queries to Alpha Vantage in the 
summer.  According to their website www.alphavantage.co:  "Composed of a 
tight-knit community of researchers, engineers, and business 
professionals, Alpha Vantage Inc. is a leading provider of free APIs for 
realtime and historical data on stocks, physical currencies, and 
digital/crypto currencies."

Has anyone had any interaction with Alpha Vantage other than the one 
comment on the quantmod github site 
https://github.com/joshuaulrich/quantmod/issues/176 on Aug 17? They 
offer support by email on their web site. I wrote them a while ago, but 
haven't had a reply.

My question was about support for the TSX. By trial and error, requests 
like TSX:POT will get intraday quotes for regular stocks. I haven't 
found how to get current quotes for ETFs or REITs.
