Leverage directly impacts margin because the higher the leverage, the smaller the margin required to open a position. For example, with 100:1 leverage, you only need 1% of the trade’s value as margin. While this magnifies potential profits, it equally accelerates losses, making risk management critical. To stay safe, traders use stop-loss orders, limit position sizes, and avoid overexposure. High leverage is generally unsuitable for beginners, as it often amplifies mistakes rather than opportunities.
