## Introduction

This sample demonstrates the use of the TIBCO StreamBase® Adapter for Hotspot FX Trading System. See Hotspot FX Trading System Adapter for details on the use and structure of this three-part adapter.

## Importing This Sample into StreamBase Studio

In StreamBase Studio, import this sample with the following steps:

- From the top-level menu, select File → Load StreamBase Sample.

- Enter `hotspot` to narrow the list of options.

- Select Hotspot FX trading system adapter from the StreamBase Market Data Adapters category.

- Click OK.

StreamBase Studio creates a project for this sample.

## 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 `HotspotFX.sbapp` file.

4. Select the Parameters tab at the bottom of the EventFlow editor view. Change the placeholder values to your site-specific values for the Hotspot FX server, port, username, and password.

5. Select the Editor tab.

6. Make sure `HotspotFX.sbapp` is the currently active tab, then click the Run button. This opens the Test/Debug perspective and starts the module.

7. In the Test/Debug Perspective, open the Output Streams view. Look for tuples emitted on the event streams conveying the state of the connection to the Hotspot FX server.

8. If the connection to the Hotspot FX server is active, look for tuples emitted on the Ticker, BBOs, and MarketBook streams.

9. In the Manual Input view, select the `ControlRequest` stream. Enter `subscribeToHeartbeat` in the `action` field and click `Send Data`.

10. Observe that heartbeat tuples now appear in the Heartbeats stream.

11. In the Manual Input view, select the `MarketRequest` stream. Enter `submitOrder` in the `action` field and appropriate values in the `currpair`, `buySell`, `amount`, `price`, `orderType`, and `comments` fields and click `Send Data`.

12. Observe a tuple from the `MarketResponse` stream containing the ID of the submitted order.

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