What is Close?

The close, or closing price, is one of four main data points used for day trading on the stock market. The other three are called low, high, and open — and all four are collectively known as OHLC. Traditionally, stock market trading was carried out during regular market hours, often only between 9am and 4pm local time, with markets closed on weekends. Cryptocurrency markets are open 24/7, so even though there is theoretically no closing price for crypto assets, the OHLC is still included on most charting platforms to signify the closing time of the regular stock market each day.
