Yahoo ticker downloader

Produces .csv, .xlsx, .json and .yaml files (All files contain same data but in a different format) for stocks, ETF, futures, indexes, mutual funds, currency, warrants and bonds. The ticker symbol, company name and exchange are saved for all symbols.

It gets its data from https://finance.yahoo.com/lookup/. Please note: it is not possible to get all the symbols due to limitations set by Yahoo.

Requirements

Python 2.7 or Python 3.5+

From python package manager (preferred):

pip install Yahoo-ticker-downloader

python setup.py install

                        you already downloaded something to the .pickle file)

                        Only export ticker symbols from this exchange (the
                        filtering is done during the export phase)

For example to download all stock symbols you run it like:

YahooTickerDownloader.py stocks

The program takes several hours before it is finished so if you don't need all symbols it might be a good idea to specify the Region of the exchanges you're interested in. The program supports suspending and resuming a download. Press CTRL+C to suspend download. Restart the program in the same working directory to resume downloading. It is possible to export a partially downloaded results using the -e flag.
