How it works ?

GFDL Market Datafeed API - How it Works ?

This API is a C++ Microsoft Windows library that interfaces with the Global Datafeeds Server Systems. The API talks to nimbleDataProPlus Desk (nimbleDataProDesk.exe) and does not provide direct connections to our servers for the components developed using the API. Instead, nimbleDataProPlus Desk (our Connection Manager) manages the session with our servers while the API provides a developer-friendly interface to query and retrieve the data.

To use the API, it requires Connection Manager (nimbleDataProDesk.exe) alongwith other necessary files as installed by nimbleDataProPlus Installer. nimbleDataProPlus Desk is a stand alone application that receives data from GFDL Servers, decompresses it, stores it and distributes it to each client application connected to it.

Newer APIs (COM and MetaStock) have similar apporach for making data connection and data retrieval.

FIX API supports FIX 4.2 standard using which, platforms can request and retrieve data from our servers.

So if you are a company having commercial software and implement this API, all your users need to do is to subscribe to nimbleDataProPlus / nimbleDataPlusLite - either directly from our website or through you - to access realtime / EOD data of the supported exchanges into your software application.

Once the API is implemented by you, your users can subscribe to our data products  directly from us
(nimbleDataPlusLite OR nimbleDataProPlus) OR you can bundle our data product with your platform as a complete solution for your clients.

Programming Languages

C, C++, MFC, C Sharp, .NET, any language that can use COM / C++ libraries
