Help on YahooFinanceData

Hello world,

I'm new to this package, trying to get some historical data from YahooFinance using below code:

MSFT = bt.feeds.YahooFinanceData(dataname = 'MSFT', fromdata=datetime.datetime(2019,1,1), todate=datetime.datetime(2019,12,31), reverse=False)

cerebro.adddata(MSFT, name = 'MSFT')  # Add the data feed

cerebro.addstrategy(SmaCross)  # Add the trading strategy

result = cerebro.run()

but got below error:

File "C:\Users\terry\Anaconda3\envs\spyder-env\lib\site-packages\backtrader\feed.py", line 203, in _start
self.start()

File "C:\Users\terry\Anaconda3\envs\spyder-env\lib\site-packages\backtrader\feeds\yahoo.py", line 352, in start
self.start_v7()

File "C:\Users\terry\Anaconda3\envs\spyder-env\lib\site-packages\backtrader\feeds\yahoo.py", line 314, in start_v7
period1 = (self.p.fromdate.date() - posix).total_seconds()

AttributeError: 'NoneType' object has no attribute 'date'

Is this because the YahooFinanceData function is not geting any data from yahoo?
or if I missed something?

@terryduan said in Help on YahooFinanceData:

bt.feeds.YahooFinanceData(dataname = 'MSFT', fromdata=datetime.datetime(2019,1,1)

Most probably because of a typo:

bt.feeds.YahooFinanceData(dataname = 'MSFT', fromdata=datetime.datetime(2019,1,1)...

should be:

bt.feeds.YahooFinanceData(dataname = 'MSFT', fromdate=datetime.datetime(2019,1,1)...
