fix - "period=max" returns "failed download" #919

Closed snafu4 closed 2 years ago

snafu4 commented 2 years ago

period='max' should adjust for interval. For example, 

yf.download(ticker, interval='1h', period='max')

returns

1h data not available for startTime=1070236800 and endTime=1640909113. The requested range must be within the last 730 days.

In the above case, it should return the last 730 days worth of data.

you probably found it by now, but I ended up here with the same problem before I saw this but the period="max" is still not working to honor hourly data:

"Please note: Yahoo Finance currently limits historical data downloads depending on the resolution of data required:

Minute Data: 7 days
2 Minute Data: 60 days
5 Minute Data: 60 days
15 Minute Data: 60 days
30 Minute Data: 60 days
Hourly Data: 730 days
Daily/Weekly/Monthly: No _limit"

You can workaround this with e.g. period="60d". If you really need yfinance to convert max then consider submitting a fix.
