A market where trading takes place on an ongoing basis. For example, a market order placed in a continuous market will be executed without delay at the best price available. Such a market trades on an uninterrupted basis during the trading session (e.g., 9 a.m. to 4 p.m. for markets in stocks and listed derivatives) or throughout the day (e.g., 24/7 for markets in forex and most electronically traded securities and derivatives). An example of continuous markets is the New York Stock Exchange (NYSE), though not at opening hours when the market opens with trades similar in fashion to call market trades.
