How to Calculate Lot Size in Forex
What is Lot Size in Forex?
Lot size refers to the volume of a trade in forex. Standard lot = 100,000 units, mini lot = 10,000 units, micro lot = 1,000 units, and nano lot = 100 units. For Nepal traders, micro and mini lots are most common due to smaller account sizes.
Why Lot Size Matters for Nepal Traders
Using the correct lot size prevents over-leveraging and protects your account from large losses. In Nepal, where many traders start with $100-$500 accounts, even a small miscalculation can wipe out your balance. For example, trading a standard lot (100,000 units) on a $200 account with 1:100 leverage would risk your entire capital on a 20-pip move.
Step-by-Step Lot Size Calculation
- Determine your risk per trade: Most experts recommend risking 1-2% of your account. For a $500 account, 2% = $10.
- Set your stop loss in pips: Example: 20 pips for EUR/USD.
- Find the pip value: For a micro lot (0.01), pip value is typically $0.10 for USD pairs. Check your broker's pip value calculator.
- Calculate lot size: Lot size = Risk amount ÷ (Stop loss in pips × Pip value). Example: $10 ÷ (20 × $0.10) = 5 micro lots (0.05 lot).
Example for Nepal Traders
Suppose you deposit $300 via Skrill into your broker account. You decide to risk 1.5% ($4.50) on a trade with a 15-pip stop loss on GBP/USD. Pip value for a micro lot = $0.10. Lot size = $4.50 ÷ (15 × $0.10) = 3 micro lots (0.03 lot). This ensures you never lose more than $4.50 on that trade.
Using a Lot Size Calculator
Many brokers offer free lot size calculators. Simply input your account balance, risk percentage, stop loss in pips, and currency pair. For Nepal traders, ensure the calculator uses USD as base currency and reflects your broker's pip values.
