The four overlapping foreign-exchange sessions of the 24-hour FX day.
Foreign exchange has no central order book - it is a network of bank dealing desks. The four “sessions” describe when those desks are open in their home cities. The market itself runs continuously from Sunday evening in Sydney to Friday evening in New York.
Liquidity peaks during the London session and during the London-New York overlap, which is when the bulk of FX turnover occurs.
