can we sell shares bought in one exchange in another

it's possible to sell shares bought on one exchange on another exchange, but there are some restrictions. 

This practice is known as cross-listing. 

But there are few conditions applied. 

Restrictions:

• Same-day transactions: You can't buy and sell the same stock on different exchanges on the same day. This is to prevent arbitrage opportunities, which are considered unethical.
• Intraday positions: If you buy a stock for intraday trading on one exchange, you can't square off that position on another exchange. You must exit your intraday position on the same exchange.
• Listing availability: Not all stocks are listed on both exchanges.

Requirements:

• Delivery of shares: You must take delivery of the shares in your Demat account before selling them on another exchange.
• Next-day trade: You can only sell the shares on the next trading day after buying them.

Example:

• If you buy 10 shares of TCS on Monday on the NSE, you can sell those shares on the BSE on Tuesday.

Additional considerations:

• Brokerage and other regulatory fees will affect your actual profit.
• Some stocks may have different prices on different exchanges.

Overall, while cross-listing is possible, it's important to be aware of the restrictions and requirements to avoid any complications.
