Your holdings show prices from the exchange with the higher previous closing price, not necessarily where you bought them. You can sell your stocks on either NSE or BSE, regardless of where you originally purchased them, as stocks in your demat account are not mapped to a specific exchange.
Generally, prices on both NSE and BSE remain the same. However, you may occasionally notice price differences due to:
1. A corporate action or IPO: Check this price difference on 15th June 2020 in Alok Industries due to a corporate action.
2. The difference in tick size: On BSE, the tick size for some stocks is ₹0.01, while on NSE, it is ₹0.05.
How to sell on your preferred exchange
Check prices on both exchanges before selling to ensure you get the best price, as the price displayed on Kite reflects the previous closing price, not the live trading price.
Add the stock to your Kite Marketwatch and sell from there, or select your preferred exchange directly from the order window when placing the sell order as shown below:
SEBI requires trading platforms to display the best available market price across both exchanges rather than maintaining constant exchange preferences. You can find more details in the BSE circular (WEB) that outlines this requirement.
