NSE sells tick-by-tick data for each segment at around 1.5-2 lakhs per year for commercial use (hearsay only, need to confirm).

Data vendors like truedata, GDF, etc., sell the 1sec data at 50-60k per segment, and 1m data at 20k per segment.

They only need 10 customers to breakeven per segment of data. Thereafter, everything they make is profit.

Live data vending seems like a complicated setup (leased line, nse direct line, etc). But becoming a vendor to NSE for historical data sounds like an attractive business.

So, becoming a vendor for NSE historical data (and afterwards adding few more exchanges) sounds like a profitable business.

What is the catch?

I'll just find out myself. I have mailed the NSE data vending team directly. Let's see what we can find out, on how to purchase the data directly from the source.

So, I spoke to the NSE in-charge for the data.

He said that the trade data alone costs 72k per year (so 7.2 lakhs for 10 years)

and if one wants to buy trade + order data - that costs 10 lakhs per year (so about 1 crore for 10 years historical data).

All of this is TBT data.

Exactly what all details would be there as part of trade data and order data is unclear.

According to what he said, you can construct OHLCV data only with the order data + trade data (the package that costs 1 cr for 10 years).
