Forex (foreign exchange) is where currencies are traded. Traders speculate on pairs like EUR/USD and GBP/JPY, aiming to benefit from price movements between buy and sell.
Margin is the amount of funds required to open and maintain a position. Margin depends on position size and leverage. Higher leverage reduces required margin but increases risk.
Leverage lets you control a larger position with a smaller amount of capital. It can amplify gains, but it also amplifies losses, so use it carefully.
The forex market typically runs 24 hours a day, five days a week, from Sunday evening to Friday evening (U.S. time), with breaks on weekends and some holidays. Sessions move from Asia to Europe to North America.
