Reactive Trader®

Reactive Trader® is a real-time FX trading platform designed to showcase reactive programming principles across the full application stack.

Originally written in WPF and .Net, and now in React, React-RxJS, Node.js and running on Hydra, we continue to evolve the platform to use the latest technologies.

Please see our Showcase page for a full list of the latest features.




Web client
  1. Fork and clone the ReactiveTraderCloud repo (see Contributing page)

  2. Install Node.js and npm

  3. Start the client:

     cd src/client
     npm install
     npm start

    This will connect to the dev back-end in the cloud.

  4. Navigate to http://localhost:1917

Manually update contracts for Trading Gateway API
  1. Open hydra-reactive-trader project in IntelliJ IDEA and run:

  2. Copy file component/gateway/trading/api/build/generated-sources/codecs/main/resources/trading-gateway.hyer to UI project src/client/trading-gateway.hyer

  3. Back in src/client, run:

    npm run generateCod

    This will regenerate TradingGateway.ts (file://./src/client/src/generated/TradingGateway.ts)

Run against local Backend Services
  1. Follow instructions to start Backend Services

  2. Run:

    VITE_HYDRA_URL=ws://localhost:8929 npm start


We practice continuous integration and deployment. Every branch and pull request triggers a build and deployment to an ephemeral environment. Merging to master causes a build and deployment to our development environment.


Please see our contribution guidelines.
