Leverage is the most misunderstood concept in retail trading. The phrase "high leverage helps small accounts grow fast" is technically true and practically destructive.
What leverage actually is
Leverage is the ratio of position size to required margin. 1:100 means $1 of margin controls $100 of position. It does not give you free money. It defines how much margin the broker demands to hold a position.
What leverage is not
- Leverage does not change the dollar P&L of a price move.
- Leverage does not increase your edge.
- Leverage does not protect you from drawdown.
What leverage does
Higher leverage allows larger positions on the same margin. Larger positions amplify P&L. Amplified P&L means amplified losses, just as much as gains. The same volatility wipes a high-leverage account that a low-leverage account survives.
Real risk = position size, not leverage
Risk is determined by lot size, stop distance, and pip value. Leverage just sets how much margin is locked. A trader using 1:500 leverage with 0.1 lot is taking less risk than a trader using 1:30 leverage with 1.0 lot.
Practical advice
- Decide risk per trade in % of equity.
- Size to the stop, not to the leverage.
- If a smaller leverage feels like a constraint, you are probably oversizing.
