WebSockets – JavaScript

Introduction

To connect using WebSockets API, you will need following information :
 
– “endpoint” to connect to,
– “port number” to connect to,
– “API Key”
 
You will get all of the above once you purchase the API from our team
 
The flow of operations should be as follows :
 
1. Make a connection to the ws://endpoint:port
2. Send Authentication Request using API Key
3. Once authentication is successful, send all other data requests
4. If connection is lost for any reasons, follow same steps from 1 to 3 as above.
 
Ready, lets gets started then

Download the sample

– Download JavaScript Sample from Download Code Samples page.
– The sample is zipped. Once downloaded, extract it to some folder using WinZip or WinRar
– Open JavaScriptExample.html file in the editor. You can use Notepad, Notepad++, Microsoft Visual Studio Code or any compatible Editor
 
Note the code below in file at the top :
 

  //GFDL TODO - please enter below the endpoint received from GFDL team. If you dont have one, please contact us on sales@globaldatafeeds.in 
  var wsUri = "ws://endpoint:port";
  
  //GFDL TODO - please enter below the API Key received from GFDL team. If you dont have one, please contact us on sales@globaldatafeeds.in 
  var password = "Enter API Access Key";

 
– Enter the Endpoint, Port and API Access Key received from our team in above code.
– Save this file and run it. You can run it directly in the editor (if supported) or you can run it in your browser.
– Make sure you run the sample during market hours.

What happens when sample is run for the first time ?

– When sample is run for the first time, it sends request to server for 2 functions – SubscribeRealtime (1 symbol each from each Exchange) and GetHistory (for latest 1 minute OHLCV bars of NIFTY-I – 10 nos)
– If you run sample during market hours, you will notice updation of realtime data of few instruments at your end. You will also notice that History of some symbols is downloaded at your end.
– Which function to run – is controlled in doTest() function – as shown below.
 

//GFDL TODO : All the functions supported by API are listed below. You can uncomment any function to see the flow of request and response
function doTest()
{
	SubscribeRealtime();					//GFDL : Subscribes to realtime data (server will push new data whenever available)

– To know how each function works, you can uncomment required function, save the sample and run it.
– For easy identification, all outgoing requests are printed in black color while all incoming server responses are printed in blue color.

Trouble-shooting

Back to Top

The code outputs nothing

– Please make sure you have entered the Endpoint, Port & API Key in the sample code, saved the changes before running it.
– To see realtime data in action, you should run the sample during market hours
– If you are behind firewall, please speak to your network administrator and get the endpoint URL and port whitelisted in your firewall
 

Back to Top

I can see some output but I dont see all symbols requested / I get “Exchange Not Enabled.” message

– SubscribeRealtime function runs at least 1 symbol from each Exchange Segment. You will need to make sure you have paid for the subscription of the Exchange you are using in your request.
 
– Some examples use Contractwise symbols which might have expired. Please check code and change the symbols. Please check Symbol Naming Conventions page for more information about various ways to name symbols (especially Futures and Options).

I have requested data but it takes lot of time to receive the response

– If you have requested entire GetHistory, GetInstruments (for NSE / NFO), GetExchangeSnapshot or GetLastQuoteOptionChain, these functions return thousands of rows. So it is possible that it takes more time than other requests to return the data
 
– Please make sure you are on fast internet connection.

I have other issues not listed here

– Please drop an email to developer@globaldatafeeds.in with following :
1. Details of the request sent (exact syntax), expected response & received response
2. Screenshot of the request & response
3. API Key used
 
Once received, we will check and revert at the earliest (typically within few hours for normal queries).
