Forex Trading Platform (Development)

http://tradeworks.io/

Platform for Forex trading with a main focus for users that don't have in-depth knowledge of algorithms or some programming techniques to create complex strategies for trading. A main focus of the platform is to allow users to enter expressions (in a user-friendly editor) that will later on be evaluated as strategies for trading. There's a possibility to run back-tests to test some trading strategy against historical data and also to let some strategy run and trade automatically for some specific amount of time and retrieve real-time performance analysis of each trading strategy. The project was built using Java/Spring Boot in the back-end and Angular 4 in the front-end. The back-end was structured in a micro-service architecture manner. By that, all the different back-end and front-end requirements imposed a real technical challenge.
