Exploring Yahoo Realtime Data Feed

23 February 2010 3,449 views 18 Comments

Here is an everyone’s question. How to and from where to fetch intraday realtimedata feed. Here is the link where the yahoo finance offers real time data updates in realtime in csv format at free of cost.

http://chartapi.finance.yahoo.com/instrument/1.0/^nsei/chartdata;type=quote;range=1d/csv/

Where the ^nsei denotes the yahoo finance symbol for Nifty

For Example by replacing ^nsei with the ACC.NS(yahoo finance symbol for ACC we could be able to get the realtime intraday data for yahoo feed in csv format(1 min data). Where the Yahoo finance symbol for nse stocks can be found from Yahoo Symbol Lookup

http://chartapi.finance.yahoo.com/instrument/1.0/ACC.NS/chartdata;type=quote;range=1d/csv/

and range=1d denotes intraday data feed and range=5d denotes past 5days data feed

The below link give the realtime data feed for past 5days which could be used as a source to backfill your chart for the past 5 days.

http://chartapi.finance.yahoo.com/instrument/1.0/ACC.NS/chartdata;type=quote;range=5d/csv/

Just those who have little stuff with .Net programming could decode this csv data Plus writing few lines of Amibroker Dll Plugin will make you able to feed these free real time data into your amibroker software at free of cost which most of the traders are wasting time in paying for a realtime software

Will do some more Reverse Engineering about the real time feed fetching some time later on

Sir,
Good information. If you could do little more research and provide us the net program information and the amibroker formula,it would be great!

Dear Rajandran Bhai,

Greetings! I was just flipping through the pages of your site when I found this. Very interesting indeed. However, could you find a way to download the data from the NSE Java Chart . This would be the last word for collating purposes, as the serious pros don’t trust their DSPs alone.

Thanks

Javed

Great article! But how do I get the file? I tried data socket, but the link does not work. Do i need to parse the HTML? I would really apprecaite help here.

Rajandran R (author) said:

Yeah, Bryan I think HTML parsing is the only way to read a csv feed. The above said link works only for backfill purpose
i guess. And for real time tick data you should use some other source

Thanks Chandu, the real reason is if iam not going to do that then some one else will claim the credit for the same.
This is an open source world.

Hello,

I agree with the fact that we should not be paying for data which is freely available and we do need to reverse engineer a way to get those softwares customised and unlocked for us. I mean they just gives us yahoo data which anyways is free for us. Is there a software that can give me realtime data for free without any limitations
