The function STOCK("WTR")
in numbers 6.2.1 works well, it returns as a value today 51.94US$ and it returns also an overview window.
However, when I use STOCKH("WTR",0,"29 Mar 2020")
it returns "The requested historical date is invalid or is in the future".
a) I am assuming the abbreviation "WTR" is correct, as it works with the STOCK
function. Is there a list of available options? -- I guess it is powered by yahoo, and there is a "WTR" in yahoo
b) Would "WTR.N" specify the stock exchange in New York City?
c) I've tried various flavours of the date string. However, it either tells me it's an invalid string or the above error message.
(d) for other stocks this works well, e.g., for "APC.F"
