Datafeed Vendor Comparison

[Shantala]

@BPR,

Charts of all authorized vendors do not match as each has his own sampling protocol. There is no chart provider who claims he will not miss a single tick.

When I came to know this, I immediately stopped subscription of GDFL and FirstCharting and started fetching data from terminal. Now, I am using Yusi's utility.

Can you elaborate more on sampling protocol if you have some more info on that?

if what you are saying is true then actually there is no point in paying for data feed.

Even if some of the ticks are missed, I think after the candle is closed the OHLC values are refreshed for the last candle so that the chart should be consistent. If I remember GDFL clarified this in some thread.

Can somebody paste the same chart for GDFL?
Also the OHLC value in excel.

brother I think that better way to compare these would be to export the data to excel and then compare the OHLC as well as volume values of each bar.

If you can export such data from your platform, then just let me know tomorrow, I will provide you the same data from esignal for any symbol you ask for "NSE Stocks / Futures" in any time frame you wish. Then you can easily do the comparison.

Regards

I have extracted manually the OHLC values from the Tame for the above chart.
Please extract the OHLC to an excel preferably and share it through a file sharing site.

I will make a comparison and post.

Cost Analysis of Legal Vendor

Guys there is a lot of hue and cry as to exchanges NSE/MCX are charging high for data fees. I tend to agree but lets do some basic calculation.

Lets take a single segment FNO the most popular

For tick by tick data for NFO segment NSE charges 38.50 lakh per year to the vendor .(for software devlopment segment)
Also per user they charge Rs900 pm.

If I am data vendor I will do the pricing in such a way that the NSE cost and my own cost are separate and transparent to end customer.

Lets say the data vendor charges 2100 pm(own cost) + 900 (NSE cost)
i.e 3000 pm to the end user.

If they acquire 1000 customers which is a very conservative figure.

their income 2100 * 1000 = 21 lakh per month
Annually 21*12 = 252 lakh per Annum

Heck I am not even considering that NSE gives discount for the first 300 customers i.e the 900 pm is not charged. So that is a additional benefit of 300*900*12 = 32.40 lakh per year to the broker.


So what is the cost to the datavendor
= One time Initial cost of setting up the business , setting of server etc and integrating the datafeed to its own platform blah blah ( put any figure say 50 lakh/75 lakh) With the advancement of new tech this cost will reduce IMO, mind you this is one time cost
+
Recurring cost of NSE fees i.e 40 lakh per Annum

+ Recurring cost of Data Servers and Maintenance (Put some figure here)

+
Recurring cost of Service /Support (Put some figure here)

WoW Looks to me if somebody seriously get into this business he will be profitable in 6 months let alone 12 months

If you think 1000 is huge number lets do the calculation for 500 customers and talk.

Instead what we are getting now!! Level 1 data which is cost wise 20 lakh per year+ 360 pm per user and then vendors are giving symbol limitation 1 symbol at a time and 5 symbol at a time and 200 symbol at a time and what not non sense.
Charging generally from 900 pm to 3000 pm ....

Ok enough rant. you be the judge.

If that was the case in this digital age, then easily we could have seen some dozens of legal data vendors floating around, deploying own data server and feeder stuff cost at least a half a million dollar as initial investments not 50 L or 70 L which was only a guess here and it takes a year to reach 1000 active users for a new vendor and considering such case it takes 2.5 yrs to 4 yrs for a data vendor to reach break even points and its not hyper profitable venturing segments as assumed

eSignal does provides tick by tick data, although I cannot say that they are providing every single trade tick, or doing some sort of combining of multiple trade ticks into one, for saving the bandwidth etc. For nifty mostly there is one tick per second, but sometimes there are multiple ticks in one second as well.

I am pretty sure they do not provide Level 3 yet.

It is more technically called snapshot or consolidated data feed

 

[sumitalwar]

nse releases only snapshot data . and at ieod their data and charts in their website are only snapshot . and not tick by tick
nse captures data at predefined intervals and then releases it

how can esignal capture and give tick by tick data is a query

Thanks to TradeOptions who shared the esignal data, I did a comparison and find many mismatch more than our naked eye comparison could find.

Here have a look

Ok I am open to discussion here, whats going on and what we can conclude from here.

So it means, you meant to say's that esignal is not offering accurate data ? but i could take it other wise, Indian standard is far lower than a international provider in data segment and esignal data could be assumed to be correct than TAME data itself.

@ bpr ,

Many thanks to you to start such a nice thread. This is quite informational.

Thanks to other contributors also for enriching the thread.

Any other viewpoint apart from fxgood's for the data discrepancies?
