High-leverage trading involves using borrowed capital to increase the size of a trade, allowing traders to control larger positions with a smaller amount of their own money. For example, with 100:1 leverage, a trader can control $100,000 in assets with just $1,000 of personal funds. This strategy is common in forex, commodities, and derivatives markets.

The main advantage of high leverage is the potential for amplified profits from small price movements. However, it also significantly increases risk. Just as gains can be multiplied, so can losses, potentially exceeding the initial investment. Because of this, high-leverage trading requires strict risk management, including stop-loss orders and disciplined position sizing.

Brokers often set different leverage limits depending on the asset class and regulations in specific regions. Retail traders are especially vulnerable to the emotional strain of high-leverage positions, as volatility can lead to rapid account depletion.

In essence, high-leverage trading is a double-edged sword. It offers opportunities for greater returns but demands advanced trading skills, psychological resilience, and a clear strategy to avoid catastrophic losses. It's generally more suited for experienced traders who understand the mechanics and risks involved, rather than beginners who the promise of quick profits may lure.
