Frequently Asked Questions
A lot size represents the number of currency units you will buy or sell in a trade. Standard lots are 100,000 units, mini lots are 10,000 units, and micro lots are 1,000 units.
Proper position sizing helps manage risk and protect your trading capital. It ensures that no single trade can significantly damage your account, allowing you to stay in the game long-term.
The wider your stop loss, the smaller your position size should be to maintain the same risk percentage. Conversely, a tighter stop loss allows for a larger position size while maintaining the same risk level.
The 1% rule suggests that you should never risk more than 1% of your account balance on a single trade. This conservative approach helps preserve capital during drawdown periods.
The Complete Guide to Forex Lot Size Calculation
Effective risk management is the cornerstone of successful forex trading. Among the most critical aspects of risk management is determining the appropriate lot size for each trade. This comprehensive guide will explain everything you need to know about calculating lot sizes and managing your risk effectively.
Understanding Lots in Forex Trading
In forex trading, a "lot" refers to the size of a trade. There are three main types of lots:
- Standard lots: 100,000 units of the base currency
- Mini lots: 10,000 units of the base currency
- Micro lots: 1,000 units of the base currency

Proper position sizing is crucial because it determines how much of your capital is at risk in each trade. By carefully controlling your position size, you can:
- Limit potential losses during losing streaks
- Reduce emotional decision-making
- Improve consistency in your trading results

How to Calculate Lot Size
The formula for calculating lot size is:
Lot Size = (Account Balance × Risk Percentage) / (Stop Loss in Pips × Pip Value)
Our lot size calculator automates this process, but understanding the underlying calculation helps you make more informed decisions about your trades.
