Specific parameters (or specific meaning): - ``dataname`` The ticker to download ('YHOO' for Yahoo own stock quotes) - ``proxies`` A dict indicating which proxy to go through for the download as in {'http': 'http://myproxy.com'} or {'http': 'http://127.0.0.1:8080'} - ``period`` The timeframe to download data in. Pass 'w' for weekly and 'm' for monthly. - ``reverse`` [2018-11-16] The latest incarnation of Yahoo online downloads returns the data in the proper order. The default value of ``reverse`` for the online download is therefore set to ``False`` - ``adjclose`` Whether to use the dividend/split adjusted close and adjust all values according to it. - ``urlhist`` The url of the historical quotes in Yahoo Finance used to gather a ``crumb`` authorization cookie for the download - ``urldown`` The url of the actual download server - ``retries`` Number of times (each) to try to get a ``crumb`` cookie and download the data proxies)perioddr)urlhistz*https://finance.yahoo.com/quote/{}/history)urldownz4https://query1.finance.yahoo.com/v7/finance/download)retriesc^ ddl}d|_|jj j |jj}t}|jjr|jj|d<d}|j}d|jd<t|jjdzD]}|j|fi|}|j|j j"k7r:|j$} | j'd}|dk(r]| j'd |}|dk(ru| j'd |t)d zdz} | dk(r| dz } | j'd | } | dk(r| | | }|j+d j-d }n|d |_d|_yt1|}dj |jj2|jj} g} t5ddd}|jj6^|jj6j5|z j9}| j;dj t=||jj6^|jj>j5|z j9}| j;dj t=|t@jBjDdt@jBjFdt@jBjHdi}| j;dj ||jjJ| j;d| j;dj |dj | djM| } d}t|jjdzD]}|j| fi|}|j|j j"k7r:|jd}|jOds d|z|_e tQjR|j$d}||_y||_y#t$rd}t|wxYw#t$rYwxYw)NrzThe new Yahoo data feed requires to have the requests module installed.
