About the Lot Size Calculator
Position sizing is one of the most critical aspects of successful trading. Using the wrong lot size can either expose you to excessive risk or limit your profit potential.
What is a Lot?
In forex trading, a lot refers to the standardized quantity of a currency you are trading:
- Standard Lot: 100,000 units (~$10 per pip)
- Mini Lot: 10,000 units (~$1 per pip)
- Micro Lot: 1,000 units (~$0.10 per pip)
The Formula
Lot Size = (Balance × Risk %) ÷ (SL Pips × Pip Value)
Pro Tip: Never risk more than 2% on a single trade when trading a prop firm challenge.
