![FX Trader Application demo](Forex.png "FX Trader App Demo")

#To start this demo follow these steps:

**Prerequisite is that you have the Kaazing Websocket Gateway and ActiveMQ up and running (more information [here](https://kaazing.com/doc/5.0/about/setup-guide/index.html))**

1. Navigate in the terminal/command line to where you cloned the kaazing demos repository and to the /forex folder (ex: ~/demos/forex);
2. Navigate to /forex/feed/, here you can find:
for Linux/MacOS a script "forex.sh"
for Windows a bat "forex.bat";
**NOTE** If your ActiveMQ is **NOT** listening to tcp://localhost:61616 hen you run the script in the step above, you will have pass the URL that your ActiveMQ is listening to as the first parameter of the script, i.e.:
for Linux/MacOS - **./stock-trading-service tcp://{ACTIVEMQ.IP}:{ACTIVEMQ.PORT}**
for Windows - **.\stock-trading-service.bat tcp://{ACTIVEMQ.IP}:{ACTIVEMQ.PORT}**
4. Navigate to /forex/javascript/ and open index.html in your browser;
**NOTE** If your gateway is **NOT** accepting JMS connections on "ws://localhost:8000/jms" you will have edit the Location input to suite your gateway URI;
6. Click connect and you will see at the bottom of the page, the stock data will start to come in!
Enjoy!
