StockMarket

A super simple stock market implementation allowing users to record trades and determine dividend yields, PE Ratios, and volume weighted prices for given sample stocks.

Requires

JDK 8

REST Endpoints

Once the application is running, the following endpoints are accessible from localhost port 8080.

Get Stocks - /stock

Retrieves all of the sample stocks.

Get Stock - /stock/{id}/

Retrieves a given sample stock by its stock symbol (TEA, POP, ALE, GIN, JOE).

Calculate Dividend Yield - /stock/{id}/dividendyield/{price}/

Calculates the dividend yield for a given sample stock and a given price.

For Common stocks this is simply Last Dividend / Price

For Preferred stocks this is (Fixed Dividend Percentage . Par Value) / Price

Calculate PERatio - /stock/{id}/peratio/{price}/

Calculates the Price-to-Earnings ratio for a given sample stock and a given price.

For Common stocks this is Price / Last Dividend

For Preferred stocks this is Price / (Fixed Dividend Percentage . Par Value)

Record Trade - /stock/{id}/trade/

Record a trade for a given sample stock.

This transaction creates a trade under the given stock with the current timestamp, and a quantity, traded price, and buy or sell flag as entered in the body of the request.

An example body:

{
	"quantity":120,
	"buyOrSell":"BUY",
	"tradedPrice":2
}

Calculate Volume Weighted Stock Price - /stock/{id}/volumeweightedstockprice/

Calculates the volume weighted stock price for the given stock based on trades in the past 15 minutes.

This is calculated as the sum of price x quantity for each trade divided by the sum of all trade quantities for the given stock.

Calculate All Share Index - /stock/allshareindex/

Calculates the GBCE All Share Index using the geometric mean of volume weighted stock prices for all stocks.
