The stock market's daily open and close may one day have little meaning if an idea gaining traction on Wall Street becomes widespread.

24X National Exchange, a trading platform backed by hedge fund founder Steve Cohen, is seeking SEC approval to operate an around-the-clock exchange. There's interest in the idea from bigger players too: The New York Stock Exchange has reportedly polled market participants about interest in 24-hour access.

Several executives at companies that operate trading platforms told Yahoo Finance the shift from a traditional six-and-a-half-hour trading day to a never-ending one is becoming more likely — even if there are some concerns about volatility in late night sessions with low volume.
