This sample demonstrates the use of the TIBCO StreamBase® Adapter for Hotspot ITCH.

Running This Sample in StreamBase Studio

  1. In the Package Explorer, double-click hotspot-itch.sbapp.

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

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

  4. 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.

  5. Click the Run button. This opens the SB Test/Debug perspective and starts the application.

  6. In the Test/Debug Perspective, open the Application Output 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.

  7. 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.

  8. When done, press F9 or click the Stop Running Application button.

Running This Sample in Terminal Windows

This section describes how to run the sample in UNIX terminal windows or Windows command prompt windows. On Windows, be sure to use the StreamBase Command Prompt from the Start menu as described in the Test/Debug Guide, not the default command prompt.

  1. Open three terminal windows on UNIX, or three StreamBase Command Prompts on Windows. In each window, navigate to the directory where the sample is installed, or to your workspace copy of the sample, as described above.

  2. In window 1, type:

    sbd hotspot-itch.sbapp

  3. In window 2, type:

    sbc dequeue -v

    This window displays the tuples dequeued from the adapter's output ports.

  4. In window 3, unsubscribe from market data for all currency pairs:

    echo false,true,[ALL] | sbc enqueue Subscribe

  5. Observe in windows 2 that Tuples stop flowing from the CancelledOrders, ModifiedOrders, and NewOrders streams.

  6. In window 3, type the following command to terminate the server and dequeuer:

    sbadmin shutdown
