Start, End (Date) Historical Market Data

Alpaca Market Data
1

Hello there:

When I try to generate the **Start ** and End Dates for the API
I get : APIError: invalid start

Here is the code:

Symbol=“AAPL”
end = datetime.datetime.today()
dateeee= end- pd.tseries.offsets.BDay(1)
start=(dateeee.strftime(’%Y-%m-%d’))

Alpaca= api.get_bars(Symbol, TimeFrame.Day, start,end , adjustment=‘raw’).df

Thank you for the help in Advance!
