Terminologies overview

Hi TQnA users / @ShubhS9 , Is there any section in NSE/BSE website that explains their terminologies like how is value calculated in indices activity table, etc?

Methodology Document for Equity Indices

looking for something like this?


Thanks @Arockiya_Raja , this is incormative and i found some info i was looking for long, in this document. But

this value calculation formula i didnt find, can you tell how is it including both buying and selling cost, or one transaction is included as 1 entry only.

Example, 2 lots of 50 shares each, needing 10k for buying and 150k for selling, would show as how much on value column?
