The stocks in the demat account do not have a specific exchange mapped to them. They can be sold on either the NSE or BSE, irrespective of the exchange where they were originally purchased. The holdings on Kite will reflect the price from the exchange where the previous closing price was higher.

Generally, the prices on both exchanges should be the same. However, occasionally there may be a price difference due to various factors, such as:

1. A corporate action or IPO: Check this price difference on 15th June 2020 in Alok industries due to corporate action.
