The script is set up to automatically install all unmet prerequisite packages using pip
This script will generated a json file in the json_extracts directory filled with request stock financial data
You can run one company at a time, or a whole list of them.
Tested on Python 2.7 and 3.5

## How to Use
1. Make sure you have python 2 or 3 installed with pip on your machine
2. Install the PhantomJS Web-driver if you haven't already. You can also download the executable and set a path to it on line 150.
  * [Download-PhantomJS](http://phantomjs.org/download.html) - Official driver download page with Windows and Mac executables ready to go.
  * [PhantomJS-Debian](https://www.vultr.com/docs/how-to-install-phantomjs-on-ubuntu-16-04) - In-depth setup guide for Debian/Ubuntu users due to extra steps
  * [PhantomJS-CentOS](http://teition.com/installing-phantomjs-on-amazon-linux-fedora-redhat-centos-over-ssh/) - Setup guide for RHEL, Amazon Linux, CentOS, and Fedora.
3. git copy the repository
```R
git clone https://github.com/JECSand/yahoo_finance_stock_scraper.git
```
4. cd into the yahoo_finance_stock_scraper directory
5. Enter the command in the following format to convert a single excel file:
```R
python yahoo_surface_scraper.py "StockTicker(s)" "StatementType" "JSONFilename" "Frequency"(Optional)
```
6. Use these guidelines for your Script Parameters
* StockTicker:
    * Either a single stock symbol, or a group of them separated by commas with no spaces unless wrapped in double quotes
* StatementType:
    * Determines which of the three financial statements will be pulled for each stock. Options are:
        * income - which will grab the stock's income statements
        * balance - which will extract the companies' balance sheets
        * cash - which will get the cash flow statements for the companies
* JSONFilename:
    * Desired naming convention for the extract file. An identifying meta-data stamp will also be added.
* Frequency:
    * Optional parameter for specifying the time period frequency of the returned data. Options are:
        * Annual (Default Value) - will return the last 3 years of data at annual intervals of time
        * Quarterly - will return the last 4 quarters of data at intervals of ~3 months each
7. Your newly extracted data will be located in the json_extracts directory!
## Examples
1. The following command will return Annual Income Statement data for Apple and store it in test_income-annual_YYYY-MM-DD_HH-mm-ss.json:
```R
python yahoo_surface_scraper.py "AAPL" "Income" "test.json" "Annual"
```
2. The next command will return Quarterly Balance Sheet data for both Wells Fargo and Ford Motor Co. The data will be saved to testfile_balance-quarterly_YYYY-MM-DD_HH-mm-ss.json:
```R
python3 yahoo_surface_scraper.py "WFC, F" "Balance" "testfile" "Quarterly"
```
3. The final example will return Annual Cash Flow data for Wells Fargo, Apple, and Ford Motor Co. The data will be saved to testdemo_cash-annual_YYYY-MM-DD_HH-mm-ss.json:
```R
python yahoo_surface_scraper.py "WFC, AAPL, F" "cash" "testdemo.json"
```
