Working on

• candlesticks
• storing previous prices

TODO list:

• add previous prices (historic data)
• add candlesticks
• add more ticker symbols
• create UI to change between active ticker symbols.
• cache data to prevent overuse of API key since it is limited
• cache user data into their browser local storage to keep track of which symbols they have subscribed to already
• finally: host the website online.
