Trading bot

Description

A very basic Trading Bot that tracks the price of a certain product and will execute a pre-defined trade in said product when it reaches a given price. After the product has been bought the Trading Bot will keep on tracking the prices and execute a sell order when a certain price is hit.

Configuration

Trading bot has multiple configuration properties which consumed by Spring using @ConfigurationProperties classes.

You have to provide the next properties using any way of providing externalized properties for Spring
https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html
For example, you can create an application.properties file and place it with executable jar of the bot.

Properties are divided in two main groups:

• Connection properties.
  Here you can specify product feed and websocket urls and trading api urls as well as security and header parameters.
  By default bot will use https://api.dev.getbux.comenvironment.

# Authorization header used in both websocket and rest api connections
trading.bot.connection.authorization=
# Accepted language header used in both websocket and rest api connections
trading.bot.connection.language=
# Websocket product feed connection url
trading.bot.connection.product-feed-url=
# API url for buy trading requests
trading.bot.connection.buy-api-url=
# API url for close trading requests
trading.bot.connection.close-api-url=
# Content type header used in both websocket and rest api connections
trading.bot.connection.content-type=

• Product properties.
  These are the properties for bot's product configuration.

# Product id to trade
trading.bot.product.product-id=
# Maximum buying price. Bot will buy provided product when current quote is equal to this price
trading.bot.product.buying-price=
# The price when bot will close a position with profit.
trading.bot.product.lower-limit-price=
# The price when bot will close a position with loss.
trading.bot.product.upper-limit-price=

Notes

The relation between prices prices is validated by the next rule:
lower-limit-price < buying-price < upper-limit-price price.
