This statement is generally true in forex trading. When traders buy a currency pair, they hope that its value will increase, allowing them to sell at a profit. Conversely, when they sell a currency pair, they hope its value will decrease, allowing them to buy back at a lower price and make a profit. However, there are times when prices may move in unexpected ways, and traders must be prepared to adjust their positions accordingly. It's essential to have a solid trading strategy, risk management plan, and emotional discipline to succeed in forex trading.
