Lesson 1.7
What Are Lots in Forex?
Estimated Reading Time: 12 Minutes
Difficulty: Beginner
Why This Lesson Matters
In Lesson 1.6 – What Are Pips in Forex?, you learned that pips measure how far a currency pair moves.
But another question immediately follows:
How much of a currency pair are you trading?
A 20-pip movement can produce a very small profit or a very large profit depending on the size of the trade.
That trade size is measured in lots.
Many beginners accidentally place trades that are much larger than they intended because they do not understand lot sizes.
This lesson will help you avoid that mistake and build the foundation for proper risk management later in the Blueprint.
Learning Objectives
By the end of this lesson, you should be able to:
Define a lot in Forex.
Understand why lot sizes exist.
Identify standard, mini, micro, and nano lots.
Explain how lot size affects profit and loss.
Choose appropriate lot sizes as a beginner.
Introduction
Imagine buying rice.
You might buy:
1 kilogram
5 kilograms
25 kilograms
50 kilograms
The product is the same.
Only the quantity changes.
Forex works in a similar way.
When you trade EUR/USD or GBP/USD, you are trading a quantity of currency.
That quantity is measured in lots.
A lot simply tells the market how much currency you are buying or selling.
What Is a Lot?
A lot is the standard unit used to measure the size of a Forex trade.
Instead of saying:
“I want to buy 100,000 euros,”
a trader usually says:
“I want to buy 1 standard lot of EUR/USD.”
Lots make trading standardized and easier for brokers and traders around the world.
The Main Lot Sizes
There are four lot sizes that every beginner should know.
Table 1.7.1 — Common Forex Lot Sizes
Lot Type | Units of Base Currency |
|---|---|
Standard Lot | 100,000 units |
Mini Lot | 10,000 units |
Micro Lot | 1,000 units |
Nano Lot | 100 units |
These numbers represent the amount of the base currency being traded.
For example, in EUR/USD:
1 standard lot = 100,000 euros
1 mini lot = 10,000 euros
1 micro lot = 1,000 euros
1 nano lot = 100 euros
Standard Lot
A standard lot is the largest commonly used retail trading size.
Example:
Buying 1 standard lot of EUR/USD means buying 100,000 euros.
Because the trade size is large, profits and losses can increase quickly.
Standard lots are generally more suitable for experienced traders or traders with larger accounts.
Mini Lot
A mini lot equals 10,000 units of the base currency.
It is one-tenth of a standard lot.
Example:
Buying 1 mini lot of EUR/USD means buying 10,000 euros.
Mini lots are often used by traders who want smaller position sizes than standard lots.
Micro Lot
A micro lot equals 1,000 units of the base currency.
This is one of the most beginner-friendly lot sizes.
Example:
Buying 1 micro lot of EUR/USD means buying 1,000 euros.
Micro lots allow traders to:
reduce risk
practice with smaller amounts
gain experience while protecting capital
Many successful traders began with micro-lot trading.
Nano Lot
A nano lot equals 100 units of the base currency.
Not all brokers offer nano lots, but when available they are useful for:
complete beginners
strategy testing
educational practice
very small trading accounts
Why Lot Size Matters
Lot size directly affects how much money is gained or lost when the market moves.
For example, imagine EUR/USD moves 10 pips.
A larger lot size generally produces a larger profit or loss.
A smaller lot size produces a smaller profit or loss.
This is why understanding lot sizes is essential before trading with real money.
A Simple Example
Suppose two traders both buy EUR/USD.
Trader A
1 standard lot
Trader B
1 micro lot
The market rises 20 pips.
Both traders made the same 20-pip movement.
However, Trader A earns much more money because the trade size is much larger.
The market movement is identical.
The lot size is different.
Lots and Pips Work Together
Think of it this way:
Pips measure distance.
Lots measure quantity.
Imagine moving a bucket of water.
Walking 10 meters is the distance.
Carrying 1 liter or 100 liters is the quantity.
In Forex:
pips = distance moved
lots = quantity traded
Both are needed to calculate profit and loss.
Which Lot Size Should Beginners Use?
For most beginners, micro lots are usually the safest starting point.
Micro lots allow you to:
make mistakes cheaply
practice trade execution
learn position sizing
build confidence
protect your trading capital
Starting with large lot sizes simply because the potential profit looks attractive is one of the fastest ways to lose money.
Real-World Example
Imagine two beginners with small trading accounts.
Trader A immediately uses standard lots.
Trader B begins with micro lots.
Both experience several losing trades while learning.
Trader A loses a significant portion of the account.
Trader B loses a much smaller amount and has enough capital to continue learning.
The second trader survives long enough to improve.
In trading, survival is extremely important.
Nigerian Perspective
Many Nigerian beginners start Forex with relatively small accounts.
Because of this, micro lots are often a more practical and educational starting point than standard lots.
The goal during the early stages is not to become rich quickly.
The goal is to develop skill while protecting capital.
The Cost of This Mistake
Using Large Lot Sizes Too Early
Many beginners choose lot sizes based on the profit they hope to make rather than the amount they can safely risk.
This often leads to:
excessive losses
emotional trading
account blow-ups
loss of confidence
Better Habit
Start with the smallest practical lot size.
Increase trade size gradually as your knowledge, discipline, and account balance improve.
FX Mentor Insight™
Beginners usually underestimate the power of lot size more than the power of the market itself.
FX Mentor Principle™ #33
Control your trade size before trying to increase your profits.
Lesson Summary
A lot is the standard unit used to measure the size of a Forex trade.
The main lot sizes are:
Standard Lot = 100,000 units
Mini Lot = 10,000 units
Micro Lot = 1,000 units
Nano Lot = 100 units
Lot size determines how much money is gained or lost when the market moves.
For most beginners, micro lots provide a safer environment for learning and preserving capital.
