Market_Session_Forex is an indicator designed for forex trading that visually delineates the three primary global trading sessions on a chart: the Tokyo (Asian) session, the London (European) session, and the New York (U.S.) session. Each session is displayed in coordinated time blocks, highlighting periods of varying liquidity, volatility, and trading volume. The indicator also marks the London–New York overlap, recognized as the most active trading period with peak volume and significant price movements. This tool aids traders in identifying key market activity windows aligned with major financial centers, facilitating more informed trading decisions based on session timing.
