Bloomberg

Overview

With the Bloomberg Adapter you can bring various Bloomberg services to your interop-enabled apps. The Bloomberg Adapter is a .NET app which is part of io.Connect Desktop and is auto started with io.Connect Desktop as a hidden app. It offers sets of protocols based on Interop methods for connecting to the Bloomberg Market Data service, as well as to the Bloomberg Terminal. Currently, a more convenient JavaScript (TypeScript) wrapping API is offered only for connecting to the Market Data service. With the provided API protocols, however, you can access the Bloomberg Market Data service and control the Bloomberg Terminal features with any JavaScript, .NET, Java or COM technology.

The Bloomberg Adapter can also run in simulator mode where the API can be used without having an actual Bloomberg Terminal installed.

Available Bloomberg Functionalities

The Market Data service and several other functionalities of the Bloomberg Terminal become available to you through the Bloomberg Adapter API.

Accessing BBG Functionalities Programmatically

All available Bloomberg functionalities are accessible through the methods registered by the Bloomberg Adapter. We have provided complete descriptions of the protocols for using these functionalities (method descriptions and concise explanations of what they accept and return). Currently, only the Market Data service has a JavaScript (TypeScript) wrapper. To use all other Bloomberg functionalities, you have to invoke the respective methods from your interop-enabled apps (see how to invoke Interop methods through the io.Connect JavaScript, .NET, Java and VBA APIs).

Below is a sample representation of a protocol method description followed by an invocation example:

Interop method name: "T42.BBG.GetGroups"
Accepts: void
Returns: Array of strings with the available Bloomberg group names;

Example:

const result = await io.interop.invoke("T42.BBG.GetGroups");
const groups = result.returned.Result;

if (groups && groups.length > 0) {
    // Use the Bloomberg groups here.
};

Market Data

The Bloomberg Market Data offers retrieval of real-time/delayed streaming market data and static reference market data for securities through subscription and request/response mechanisms. Using the available Market Data protocols or APIs you can easily acquire market data provided by Bloomberg in order to show it, use it or redistribute it throughout your apps. The following functionalities are available:

Bloomberg Groups

The Bloomberg Groups are visual color-coded named groups (much like the io.Connect Channels) which the user can select from the UI of Bloomberg apps. They provide data synchronization across Bloomberg apps (e.g., if two apps are in the same colored group, when an instrument changes in one app, the other app is updated respectively). The Bloomberg Adapter API provides configurable mapping between the Bloomberg Groups and the io.Connect Channels. The following events and functionalities are available:

BBG Group context changed event (e.g., instrument update);
BBG Group context update via an io.Connect invocation method;
BBG Group context read (get) via an io.Connect invocation method;
BBG Group context update via an io.Connect Channel;
Keeping an io.Connect Channel synchronized with a BBG Group context;

Bloomberg Worksheets

The Bloomberg Worksheets are spreadsheets containing a list of securities to monitor. The following Bloomberg Worksheets manipulations are available:

Get a BBG Worksheets list via an io.Connect invocation method;
Get the BBG Worksheet context (instrument list) via an io.Connect invocation method;
Create BBG worksheets;
Update (add/remove/set) BBG Worksheet context via an io.Connect invocation method;

Bloomberg Functions

The Bloomberg Terminal has built-in functions which execute various kinds of data analyses on markets or securities. The Bloomberg Adapter API allows you to invoke Bloomberg functions with a custom set of arguments.

Bloomberg Simulator

The simulator mode of the Bloomberg Adapter enables you to use the provided APIs when developing or testing without the need for an actual Bloomberg Terminal installed.

To start the Bloomberg Adapter in simulator mode, use the --terminalType=sim command line argument when starting the Bloomberg Adapter from its executable file.

Alternatively, you can use the following app configuration, which will allow the Bloomberg Adapter app to appear in the io.Connect launcher and start in simulator mode:

{
    "title": "Bloomberg Simulator (DEV)",
    "type": "exe",
    "name": "bbg-simulator",
    "icon": "http://localhost:22080/resources/icons/wpf.ico",
    "autoStart": false,
    "hidden": false,
    "service": false,
    "details": {
        "useShellExecute": true,
        "path": "%GDDIR%/../GlueBloombergBridge/",
        "command": "Glue42.Bloomberg.Bridge.exe",
        "parameters": "--terminalType=sim",
        "left": 100,
        "top": 75
    }
}

FDC3 Compliance

All versions and modes of the Bloomberg Adapter are fully compliant with the FDC3 standards.
