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 hotspot-itch.sbapp file.

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

  5. Select the Connection Properties tab and enter valid values for Host Name, Port Number, User Name, User Name, and Password.

  6. Select the Subscription Properties tab and observe that the adapter, by default, subscribes to market and ticker data for all currency pairs. To subscribe to one or more specific currency pair, replace ALL with a comma-delimited list of currency pairs, such as EUR/USD, USD/JPY.

  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 Hotspot Itch server is configured correctly, look for tuples emitted on the Status stream indicating the adapter has connected and logged in successfully. Look for tuples on the other output streams indicating market and tick data is flowing.

  9. In the Manual Input view, select the Subscribe stream. Enter false in the isSubscribe field, true in the isMarketData field, and add a single element containing ALL in the currencyPairs field. Click Send Data and observe that tuples stop flowing from the CancelledOrders, ModifiedOrders, and NewOrders streams.

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