1. No, as a member of the exchange (not just us, any brokerage in India) we get what is called a 1 second snapshot data and not tick by tick data. Typically 1 second snapshot data will have around 4 to 5 ticks in 1 second, but tick by tick data could have a few hundred also in just the same second.
2. Pi would be based on snapshot data, so the 1 minute OHLC will be based on those 4 to 5 ticks we get in a second. This 4 to 5 ticks that we get in a second, could vary from the 4 to 5 ticks someone else gets.
3. Sum of volumes for the whole day should ideally match.
