Here's a simplified and friendly version of your text, without using any symbols or bullet points: The Calcutta Stock Exchange, located at Lyons Range in Kolkata, is the second oldest stock exchange in South Asia. It was established in 1908 and was once the second-largest stock exchange in India. Over the years, many regional stock exchanges have closed as part of SEBI’s exit policy, including the ones in Bangalore, Hyderabad, and Madras. However, the Calcutta Stock Exchange is still holding on. Although SEBI has asked it to shut down, the matter is currently being reviewed in the Calcutta High Court, so its future remains uncertain for now.
