Introduction

The TIBCO StreamBase® Adapter for Deutsche Bank Autobahn FX allows a StreamBase application to retrieve market data from, and submit trade requests to, a Deutsche Bank AutobahnFX trading system. The adapter appears as two icons on the EventFlow canvas in StreamBase Studio — one for market data and a second for trades. The two icons share a single AutobahnFX server connection, which is configured through the market data adapter. The EventFlow canvas icons for this adapter are:

  • Market Data — Retrieves spot, forward, and swap quotes.

  • Trades — Submits trade requests on quotes received from the market data adapter.

Each adapter icon has its own set of input and output ports, the fields for which are defined later in this document. Properties are shared by the two adapters and entered through the market data adapter's property view. A single global ID entered in both adapters' properties views binds the adapters.

The market data input adapter icon has two input ports for submitting subscription requests and quote ladders and four output ports for receiving status events, quotes, IDs associated with successful subscriptions, and notification that subscriptions have ended.

The trades output adapter icon has one input port for submitting trade requests and two output ports for receiving status events and trade responses.

Notes

StreamBase does not license or distribute Deutsche Bank AutobahnFX libraries. These must be obtained from Deutsche Bank and installed prior to running the adapter. The Deutsche Bank Autobahn adapter will typecheck without the AutobahnFX API libraries being available, but the adapter will not run until the API libraries are properly loaded.

Installing the Deutsche Bank AutobahnFX API libraries

You must obtain the Deutsche Bank AutobahnFX Java libraries, version prod-11-2-5 or above, directly from Deutsche Bank. The easiest way to make the AutobahnFX API accessible to StreamBase is to copy all the AutobahnFX API JARs into the StreamBase installation in the lib/ext directory. The Deutsche Bank AutobahnFX API is composed of more than 20 JAR files.

If copying the JAR file to lib/ext is impractical, then for running Deutsche Bank adapter applications in StreamBase Studio, you must add all the AutobahnFX API JARs to the Java Build Path. For running Deutsche Bank adapter applications from the command line, you must add the AutobahnFX API JARs to the server's CLASSPATH, either by setting an environment variable, or via the <java-vm> element of the server configuration file as described below.

Running Applications With The Deutsche Bank AutobahnFX Adapter

Running From StreamBase Studio

To run a StreamBase application containing a Deutsche Bank AutobahnFX Adapter from StreamBase Studio, ensure that the following configuration step has been taken:

  • Add all the Deutsche Bank AutobahnFX jars to your project's list of referenced libraries. In StreamBase Studio's Package Explorer view, right-click your project's top-level folder and select Build Path → Add External Archives from the context menu. Select the appropriate JAR files from the file dialog.

Running From The Command Line

To run a StreamBase application containing a Deutsche Bank AutobahnFX Adapter from the command line, ensure that the following configuration step has been taken:

  • In the server configuration file (usually, sbd.sbconf), add a <java-vm/jar> element for each of your AutobahnFX JAR files, or add a <java-vm/dir> element that specifies the directory containing these JAR files.

    On Windows: 

    <java-vm>
  <jar file="c:/my_db/lib/deutsche-autobahnfx-api.jar"/>
  <jar file="c:/my_db/lib/deutsche-autobahnfx-cache.jar"/>
...

    or: 

    <java-vm>
  <dir path="c:/my_db/lib/"/>
...

    On Linux or Solaris: 

    <java-vm>
  <jar file="/opt/db/lib/deutsche-autobahnfx-api.jar"/>
  <jar file="/opt/db/lib/deutsche-autobahnfx-cache.jar"/>
...

    or: 

    <java-vm>
  <dir path="/opt/db/lib/"/>
...

Properties

With the exception of the global ID, all adapter properties entered in the Market Data adapter's Properties view apply to both the market data and trade adapters. The global ID for the trade adapter must be specified independently in its Properties view.

Property Description
AutobahnFX Properties File The name of the file containing AutobahnFX API properties. See the AutobahnFX properties file shipped with the adapter sample, FxApi.properties, for the format and content of this file.
Initial Subscriptions File The name of the file containing subscription requests processed when the StreamBase application starts. See the initial subscription file shipped with the adapter sample, InitialSubscriptions.txt, for the format and content of this file.
Worker Thread Count The number of worker threads that will process incoming Quotes.
Default Tradable Amount The amount used to retrieve the quote when quote rungs are unavailable for a particular currency pair.
Quote Cache Size The maximum number of elements to keep in the quote cache, which contains quotes available for trading.
Quote Timeout The time, in seconds, a quote remains in the cache and available for trading.
Reconnect Interval The number of seconds to wait between attempts to (re)connect to the AutobahnFX server.
Global ID The global identifier for this adapter instance.
Log Level Controls the level of verbosity the adapter uses to send notifications to the console. This setting can be higher than the containing application's log level. If set lower, the system log level is used. Available values, in increasing order of verbosity, are: OFF, ERROR, WARN, INFO, DEBUG, TRACE, and ALL.
Include Latency Data Controls whether or not two optional latency measurement fields (QuoteArrivalTime and QuoteHandoffTime) are included in Quotes output tuples. Both fields are of type long and contain nanosecond timestamps.

Using the Adapter in a StreamBase Application

This section demonstrates how to use the AutobahnFX adapter in a StreamBase application. As shown in the EventFlow excerpts below (taken from the adapter's sample application), the adapter appears as two icons on the canvas: one for Market Data and one for Trades. See the sample application for the full context of these examples.

Each adapter has a specific set of input and output ports to communicate with the surrounding application. As with other StreamBase adapters and operators, you can optionally enable an Error Output Port, as described in Using Error Ports and Error Streams.

Adding the Adapter to an EventFlow Application

Add an instance of the adapter to a new StreamBase EventFlow application as follows:

  1. In StreamBase Studio, create a project, including an empty StreamBase EventFlow application file to host the adapter.

  2. From the Operators and Adapter drawer of the Palette view, drag a Deutsche Bank Market Data component to the canvas.

  3. From the Operators and Adapter drawer, drag a Deutsche Bank Trade component to the canvas.

  4. Import the template AutobahnFX properties file, FxApi.properties, from the sample application shipped with this adapter. To use the new EventFlow application with a simulated AutobahnFX server (recommended for initial testing), leave this file unchanged. Otherwise, make changes necessary to match the configuration at your site, including providing account credentials, a server ID, a realm URL, and keystore information. .

  5. Select the Editor tab at the bottom of the EventFlow editor.

  6. Double-click the Deutsche Bank Market Data adapter icon, and in the Properties view, select the Adapter Settings tab.

  7. Select the AutobahnFX properties file imported above.

  8. Enter a Global ID used to bind the Market Data and Trade adapters.

  9. The remaining Market Data adapter properties are optional and may be left with their default values.

  10. Double-click the Deutsche Bank Trade adapter icon, and in the Properties view, select the Adapter Settings tab.

  11. Enter the same Global ID as used for the market data adapter above.

  12. Connect Input and Output Streams to the adapters' input and output ports.

  13. Configure the schemas of the input streams with the fields listed in the sections above describing market data and trade adapter input ports. Note that the adapter will generate typecheck errors when the input streams are missing required fields, when unexpected fields are present, or when fields are of the wrong type.

Description of This Adapter's Ports

AutobahnFX Market Data Adapter Ports

Typechecking and Error Handling

The AutobahnFX adapter uses typecheck messages to help you configure the adapter within your StreamBase application. In particular, the adapter generates typecheck messages for the following reasons:

  • A required property such as the AutobahnFX configuration file or Global ID is missing.

  • The specified AutobahnFX configuration file or initial subscriptions file does not exist.

  • One or more required fields in an input schema are missing or of the wrong type.

  • One or more unexpected fields are present in an input schema.

The adapter emits status tuples and/or warning messages during runtime under various conditions, including:

  • The adapter fails to connect or loses its connection to the AutobahnFX server.

  • An invalid subscription or trade request tuple is enqueued to the adapter.

  • The adapter incurs an error emitting a tuple.

  • The adapter adapter is suspended or resumed.

Suspend and Resume Behavior

When suspended, the adapter continues to receive and process AutobahnFX messages, but no longer emits tuples on its output ports.

When resumed, the adapter once again starts emitting tuples on its output ports.
