• Extended trading is trading that takes place on electronic trading platforms outside the official trading hours of the exchange.

  • The extension of trading hours depends on which asset or security is being traded. Stock exchanges in the US are open from 9:30 am to 4:00 pm. EST. Extended trading takes place outside these hours.
  • Less volume during extended hours can lead to increased risk and volatility, although it can also open up opportunities for the astute trader.
