Using excessive leverage is a dangerous mistake that increases both profits and losses. Using high leverage to boost profits may feel appealing, but it significantly increases risk. A small market movement against you can wipe out your account. To avoid this, use leverage sparingly and coordinate it with your risk management strategy. Never risk more than you can afford to lose. Focus on achieving stable, consistent profits rather than chasing big wins. By keeping leverage low, you protect your capital and maintain control over your trades, ensuring you stay in the market long-term without facing catastrophic losses.
