Running This Sample in StreamBase Studio

  1. In the Project Explorer view, open the sample you just loaded.

    If you see red marks on a project folder, wait a moment for the project to load its features.

    If the red marks do not resolve themselves after a minute, select the project, right-click, and select Maven>Update Project from the context menu.

  2. Open the src/main/eventflow/packageName folder.

  3. Open the GAIN-GTX-Sample.sbapp file.

  4. Select the adapter icon to open the Properties view for the adapter.

  5. Select the Adapter Properties tab and enter the Server URL, User Name and Password of the GAIN GTX server to which you have access.

  6. Save the module.

  7. Click the Run button. This opens the SB Test/Debug perspective and starts the module.

  8. In the Test/Debug Perspective, open the Output Streams view. If connectivity to your GAIN GTX server is configured correctly, look for tuples emitted on the Status stream indicating that the adapter has established a connection to the server.

  9. In the Manual Input view, select the Commands stream. Enter disconnect in the command field. Click Send Data and observe that a tuple is emitted on the Status stream, and a message is printed to the console to indicate the adapter disconnected from the GAIN GTX server.

  10. In the Manual Input view, select the Commands stream again. Enter connect in the command field. Click Send Data and observe that a tuple is emitted on the Status stream, and a message is printed to the console to indicate the adapter has reconnected to the GAIN GTX server.

  11. In the Manual Input view, subscribe to get market data for the EUR/USD currency pair by selecting the Subscriptions stream and entering marketdata in the command field and EURUSD in the symbol field. Click Send Data and observe that a new tuple has been emitted on the Status stream indicating that the adapter has subscribed to receive Market Data for the given symbol. You can also observe that tuples are emitted on the MarketData stream as new market data ticks are received from the GAIN GTX server.

  12. In the Manual Input view, subscribe for trading operations for the EUR/USD currency pair by selecting the Subscriptions stream and entering trading in the command field and EURUSD in the symbol field. Click Send Data and observe that a new tuple has been emitted on the Status stream indicating that the adapter has subscribed for trading for the given symbol. You are now ready to send and cancel orders for this currency pair using the Trades port.

  13. When done, press F9 or click the Terminate EventFlow Fragment button.
