In forex, profit refers to the amount of money earned by a trader from a successful trade. This is calculated as the difference between the buy and sell price of a currency pair, multiplied by the amount of currency bought or sold. For example, if a trader buys 100,000 units of EUR/USD at 1.2000 and sells them at 1.2050, the profit earned would be 50 pips, or $500 (assuming a pip value of $10 per pip for a standard lot). It’s important to note that forex trading involves risk and traders can also experience losses.
