@lefig have you checked the dataframe is not empty? Eg. you can print it beforehand
Hi @saeedamen ,
Thank you for coming back to me. I am still investigating but am at present unable to download any data. I get a strange error...
File "c:\work\quant\python\data\findatapy\findatapy\market\datavendorweb.py", line 496, in load_ticker data_frame = data_frame.to_frame().unstack() File "C:\work\python\3.6.7\python-3.6.7.amd64\lib\site-packages\pandas\core\generic.py", line 5180, in getattr return object.getattribute(self, name) AttributeError: 'DataFrame' object has no attribute 'to_frame'
And the code responsible: if run_example == 1 or run_example == 0:
# downloaded S&P500
md_request = MarketDataRequest(
start_date="decade", # start date
data_source='yahoo', # use Bloomberg as data source
tickers=['Apple'], # ticker (findatapy)
fields=['close', 'open'], # which fields to download
vendor_tickers=['aapl'], # ticker (Yahoo)
vendor_fields=['Close', 'Open'])# which Bloomberg fields to download)
df = market.fetch_market(md_request)
Yahoo changed their API, so pandas_datareader, which broke findatapy's Yahoo downloader. I've rewritten the Yahoo downloader in findatapy to use yfinance (pip install yfinance). If you remove findatapy and install the latest version (with yfinance too), it should work.
Hi there,
Firstly, thank you for three excellent projects. Only recently have I tried plotting a chart using Chartpy. And this has been unsuccessful. I am struggling to figure out why the chart output is not being rendered. I get a PNG and matplotlib display that is blank. The logs are:

I would really appreciate any thoughts or suggestions.
