Clear explanation • Lot size types • Examples • Risk impact
Definition
In forex, a lot refers to the standardized quantity of currency units you trade. It determines how much each pip movement is worth in your trade.
Types of Lot Sizes
- Standard Lot: 100,000 units of the base currency.
- Mini Lot: 10,000 units of the base currency.
- Micro Lot: 1,000 units of the base currency.
- Nano Lot: 100 units of the base currency.
Example
Trading EUR/USD with a standard lot (100,000 units) means each pip is worth about $10.
With a mini lot, each pip is worth about $1.
With a micro lot, each pip is worth about $0.10.
Why Lot Size Matters
Lot size directly affects your risk and potential profit. Larger lots increase both the reward and the possible loss per pip.
Choosing the Right Lot Size
- Consider your account balance and risk tolerance.
- Many traders risk 1–2% of their account per trade.
- Start with smaller lots if you are new to trading.
Risk Management Example
If your stop-loss is 50 pips:
• Standard lot = $500 risk
• Mini lot = $50 risk
• Micro lot = $5 risk
