Dividend removed on exDate

[claha]

The current api endpoint "removes" the dividend on the exDate, I think it should be on paymentDate. To work around this there is an additional endpoint (for stocks and etfs at least) that could be defined and used.

AVANZA_API_STOCK_DETAILS_URL = AVANZA_API_STOCK_URL + "/details
AVANZA_API_ETF_DETAILS_URL = AVANZA_API_ETF_URL + "/details

Which could be used like this to check all events, if exDate has passed they seem to be in the pastEvents.

details = get_stock_details(id)
for dividend in details["dividends"]["events"] + details["dividends"]["pastEvents"]:
   ...
