hello,
how can i save the backtrader.feeds.yahoo.YahooFinanceData's data into csv file?
i loaded the data like below code, but cannot find any method or variable to save its back data into csv .

data = bt.feeds.YahooFinanceData(
    dataname='AAPL',
    fromdate=datetime.datetime(2020, 1, 1),
    todate=datetime.datetime(2020, 12, 31),
    reverse=False)

is there some code like below?

data.to_csv(FILE_NAME)

thanks.
