Lot Sizes & Leverage
Understanding position sizing and borrowed capital
Lot size determines how many units of currency you're trading:
- Standard Lot: 100,000 units (~$10/pip) - Mini Lot: 10,000 units (~$1/pip) - Micro Lot: 1,000 units (~$0.10/pip) - Nano Lot: 100 units (~$0.01/pip)
Leverage allows you to control larger positions with less capital: - 1:10 leverage: $1,000 controls $10,000 - 1:50 leverage: $1,000 controls $50,000 - 1:100 leverage: $1,000 controls $100,000 - 1:500 leverage: $1,000 controls $500,000
⚠️ WARNING: Leverage is a double-edged sword. It amplifies both profits AND losses equally.
Margin = the capital required to hold a position. With 1:100 leverage, opening a $100,000 position requires $1,000 margin.
Margin Call: When your equity drops below the maintenance margin level, the broker forces position closure.
Pro tip: Use micro lots when starting live trading — the lessons are the same but the tuition is cheaper.
Pro tip: Effective leverage matters more than available leverage. If you use proper position sizing, you're never using more than 5:1 effective leverage..
Common mistake: Using maximum leverage (1:500) as a beginner. Better: Start with 1:10-1:20 leverage. High leverage wipes accounts..
Common mistake: Thinking leverage is free money. Better: Leverage is borrowed capital. Your losses are amplified just as much as profits..
