Request for enhancement

[vsoler]

Dear Elias,

This a request for enhancement rather than an issue.

Is it possible that you accept an arbitrary range in your get_prices function? for example, 10d, 15y ... and so on? If it is possible, it would help me a lot.

Thank you.

Hey currently not planned. I just expose the ranges that are supported by Yahoo internally (i.e. I send the range and interval as a query parameter and these are the only ones Yahoo accepts).

I generally always use the startdt and enddt parameters myself as they allow for this flexibility.

You could for example do the following:

using YFinance
using Dates

function get_prices_r(ticker::String,range::Union{TimePeriod,DatePeriod};args...)
    startdt,enddt = now()-range, now()
    get_prices(ticker; startdt=startdt,enddt=enddt,args...)
end

get_prices_r("AMD",Day(10))

get_prices_r("AMD",Minutes(5)) # This will error when markets are closed (more info below)

Minute(5) should work once the markets are open - can't test it now.
It will error now because it will try to get prices from 5 minutes ago (( DateTime("2024-09-09T00:29:51.796"))) to now (DateTime("2024-09-09T00:34:51.796")) and no market is open at the moment so the query returns nothing.
