When did stock exchanges start and end?

Excuse me, but could you clarify your question a bit further? The phrase "When did stock exchanges start and end?" seems to imply a misunderstanding of how stock exchanges operate. Stock exchanges, being institutions that facilitate the buying and selling of securities, such as stocks, do not have a definitive "start" and "end" point in the traditional sense. However, if you're asking about the historical origins of stock exchanges and when they first emerged, the answer varies depending on the specific exchange. For instance, the Amsterdam Stock Exchange, considered one of the world's oldest, dates back to the 17th century. On the other hand, if you're referring to the potential end of stock exchanges, it's a highly speculative question, as they have been a fundamental part of the global financial system for centuries and continue to play a crucial role in facilitating capital formation and economic growth. Perhaps you're asking about the trading hours of stock exchanges? If so, these can vary from country to country and exchange to exchange, but generally, stock exchanges operate during regular business hours, with some offering pre-market and after-hours trading sessions as well.
