Google Realtime Intraday Backfill Data

How to get the realtime intraday backfill data. Many of us know that google provides 15 day intraday 1min backfill. But where is the source
how the softwares like Manshi RT and volume digger getting those backfill data?

The below link gives the realtime backfill data which most of the softwares are probably using it as a source for realtime datafeed,c,o,h,l&df=cpct&auto=1&ts=1266701290218


q= stock symbol on Google finance
x= exchange symbol
i= interval (here 60 means 60 sec (1 minute interval))
p= no of period(here 5d denotes 5 days of data)
f= parameters (day, close, open, high and low)
df= difference (cpct is may be in % change )
auto =1,
ts = time start… if you cut the last 4 digits…the rest gives the start day in seconds

you can choose your own set of value depending upon your need.

The following link gives the 1 min Realtime data for Nifty,o,h,l,c,v

Using the above explanation we can build any formats(1min,5min, 15min,hourly) of real time data and can be use as a backfill
to feed charting softwares like Amibroker, Metastock, Ninja Trader etc

To get 1 min Data,o,h,l,c,v

To get 5 min Data,o,h,l,c,v

to get 15 min Data,o,h,l,c,v

to get Hourly Data,o,h,l,c,v

want to know how to and from where to fetch intraday realtimedata feed using yahoo finance. Here is the link where the yahoo finance offers real time data updates in realtime in csv format at free of cost.

    Dear Sir,

    Thank you for your wonderfull and lucid posts.

    Appreciate if you can give the link where to find the procedure
    for feeding real time google data to Amibroker.

    I have been scanning each of your page from last and have reached up to 176 but still not found the same…

    However during this scanning I have come across many posts which have
    truly enlightened me.

    I have downloaded Motivewave but find that it is slow and the data
    does not auto upload (at least today), one has to manually refresh the page to get the latest quotes and charts.

    Please let us know how to feed google downloaded as per above post to Amibroker (manually or auto)..

    Best regards,

    Stupid question,
    How do I interpret the date? Also seems that the smallest interval is 8sec but the data is the same as i=10. Also what is the time difference between lines? Sorry if these questions are seem simple, and thanks for the help.

  • Prahalad Das July 11, 2012, 9:57 pm

    Hello Rajandran Sir,

    I have found that many companies are selling historical quotes of “FUTURE OF INDIVIDUAL STOCK” ; I think they must be bluffing as it could be approximation but for sure not authentic one.

    As future quote would have 3MONTHS contract for each stock on a given day, so which means they have to store 3 data points for every minute. If we take option into view the scenario becomes even complicated.
    SO MY WILD GUESS is that; they are bluffing about having historical data of “f&o” quotes.

    SIR, if you have seen these historical F&O from these acclaimed data provider ? Please let me know your view or your experience with historical F&O quotes.

    With Best Regards,
    – Prahalad Das

  • Arpan April 27, 2013, 3:40 pm

    I ‘ve used Google Finance to download realtime data. But what I want from datafeed is last 1 minute data, for ex. if there is a data of 1 whole day which is around 374 lines, I just want last 1 line and not all the lines. Or is it possible to extract a particular time line (i.e. 12.30 minute) from Google finance. I mean olny one line and not the full data from 9.15 to 12.30

  • Keerthi May 23, 2013, 3:28 am

    Please note that the data is returned in CHLO format rather than OHLC immaterial of the order of parameters passed.
