Why I chose to do this project:

As a noob interested in the stock markets, I decided to build a bot which gives the latest stock price of the listed companies. 

API used: 

ruby gem - stock_quote, an API which helps to retrieve book, chart, company, delayed quote, dividends, earnings, effective spread, financials, stats, lists, logo, news, OHLC, open/close, peers, previous, price, quote, relevant, splits, time-series, volume by venue and batch requests through IEX (iextrading.com/developer)

Pseudocode:
