# Robinhoops

[Live Site](http://www.robinhoops.io)

Robinhoops is a Robinhood.com clone built with Rails and React/Redux that allows users to invest in the top NBA athletes.

Athletes' prices are updated every few seconds based on their stats and recent overall Twitter sentiment.

## Twitter Sentiment

Credit to sentimental gem

Robinhoops scrapes Twitter for recent tweets and then maps each word and assigns an overall score based on each tweet.

Using Nokogiri and HTTParty

```ruby

    def self.scrape_tweeter(athlete_name)

        names = athlete_name.split(" ")

        firstName = names[0]

        lastName = names[1]

       url = "https://twitter.com/search?q=" + lastName + "%20" + firstName + "&src=typd"

       unparsed_page = HTTParty.get(url)

       parsed_page = Nokogiri::HTML(unparsed_page)

       tweetDivs = parsed_page.css('div.tweet')

       scrappedTweets = []

       tweetDivs.each do |div|

        tweetBody = div.css('p.TweetTextSize.js-tweet-text.tweet-text').text

        tweetUsername = div.css("span.username").text

        tweetTimestamp = div.css("span._timestamp").text

        scrappedTweets.push({tweetBody: tweetBody, tweetUsername: tweetUsername, time_created: tweetTimestamp})

    end

       return $analyzer.score scrappedTweets

    end

```

## How it Works

All new users receive $2000.00 and a free stock/athlete.

To be really specific, Robinhoops creates a new user and then store snapshots of portfolio value and twitter sentiment every 20 seconds. These data points are then used to graph stock and user portfolio value volatility. An athlete's price will only fluctuate if users on trading that specific stock.
