The continuous liquidity of the Forex market is based on the fact that the markets are opened for 24 hours a day in any part of the world. From the New Zealand open, going through Asia and until the last American closing, trading happens for 24/5, from Sunday evening until Friday night. There are three main sessions which bring most of the market volume, the three of them linked to the open and close of the three main stock markets: London, New York and Tokyo. These three sessions overlap during a few hours. These are the times where the markets are more active and usually bring the best opportunities. This screen should help you find these lapses.
