Forex trading works by pairing two currencies, such as USD/EUR. When you trade, you predict whether the base currency (USD) will strengthen or weaken against the quote currency (EUR). For example, if you believe the US economy will outperform the Eurozone, you buy USD/EUR. If the rate rises from 1.1000 to 1.1200, you profit from the difference. Conversely, if you sell, you profit from a falling rate. Each trade is executed in lots—standard (100,000 units), mini (10,000), or micro (1,000). Belgian retail traders often use mini or micro lots to manage risk. Leverage amplifies your buying power; for instance, with 30:1 leverage (the FSMA maximum), a $1,000 deposit controls $30,000 in currency. However, leverage also magnifies losses. In Belgium, you must trade through a broker that offers a trading platform like MetaTrader 4 or cTrader. You deposit funds using Bank Transfer, Skrill, or USDT, then open trades based on technical analysis, economic news, or trends. The spread—the difference between bid and ask price—is your main cost. For USD pairs, spreads are typically low due to high liquidity. A practical example: you deposit €500 via Skrill, convert to USD, and buy USD/JPY. If the rate moves 50 pips in your favor, you earn roughly $25 with a mini lot. Remember, success requires strategy, discipline, and understanding local regulations.
