# Description:  Create and instance of class c_stock and call its 
#               get_eod_stock_date function to obtain daily closing prices
#               and get_real_time_stock_quotes to obtain the latest price quote.

from c_stock import c_stock
from api_secrets import api_token

# Get end of day and real time quote data for the AAPL stock.

# Instantiate c_stock.
stock = c_stock(api_token, 'AAPL', '2022-05-24', '2023-05-23')

# Get end of day closing prices and write them to a JSON file.
stock.get_eod_stock_data('c:\\stock_data\\eod.json', 'JSON')

# Get the real time quote data and write them to a JSON file.
stock.get_real_time_stock_quote('c:\\stock_data\\rtq.json')
