FAQ
How do I calculate forex lot size?
Lots = (account × risk%) ÷ (stop-loss in pips × pip value per lot). With a $10,000 account, 1% risk, a 20-pip stop and $10/pip per standard lot, you'd trade 0.5 lots.
What is the pip value per standard lot?
For pairs quoted in USD (EUR/USD, GBP/USD, AUD/USD…), one pip on a standard lot is about $10, a mini lot $1, and a micro lot $0.10. For other quote currencies, use the Pip Value Calculator first.
What are standard, mini, and micro lots?
A standard lot is 100,000 units of the base currency, a mini lot is 10,000 units, and a micro lot is 1,000 units. Brokers let you trade fractional lots like 0.37.
