In terms of Forex trading, lot size indicates how much currency unit you are buying and selling. Let’s describe the term with meaningful examples.
What Is Lot In Forex

A lot is an important element in forex trading, and also in forex risk management.
A lot is defined as the size of a transaction, which is used for trading forex. It also refers to a bundle of units in the currency market.
From the beginning of the trading time, currencies were traded in specific amounts, which were known as Lots. Selecting an effective lot depends on the type of account you have with your Forex broker.
Apart from these, there are a few categories of forex lot sizes. We will go through all of these categories one by one.
By using an example of a lot, we are going to make it easier for you to understand.
Suppose, you are willing to trade the currency pair EUR/USD. For trading currencies, you have to select a lot size or transaction size.
After selecting a Forex broker, you will be suggested by that broker to choose a specific unit to open a position in the trading market.
If the suggested amount is 1000 units of USD/EUR to open a position, then this is your lot size. This size is considered a micro lot.
That means you have chosen to buy a micro lot of USD/EUR. Moreover, you are buying $1000 worth of the US dollar at the exchange rate of 1.3530.
The rising exchange rate will indicate your profitable way of trading, and the decreasing exchange rate will indicate the loss.
To calculate profit or loss in Forex trading, you have to multiply the PIP VALUE with the LOT SIZE.
Suppose, the LOT SIZE is 10,000 units and the price of the base currency is rising from $1.3456 to 1.3556. So, it moved upwards by 100 PIPS.
Types Of Forex Lot Size

There are few categories of lot size in Forex trading. These categories depend on the account size of traders. On the other hand, Lot sizes also depend on the trader’s account equity and leverage.
The units are fixed for each of the lot sizes starting from Nano size to Standard.
We will give a short description of one by one.
The nano lot is the smallest lot amount starts from 100 units.
In the forex trading, traders have the facility to select the trading position size according to the trading amount. Nano lot helps traders to trade with a very small amount.
You have to check the pip amount before starting a trade. The pip value will be decided by the brokers.
In a nano lot, you can start with a small amount which I already mentioned before.
Starting with a small amount help you to control your risk amount, and it is convenient for your trading.
By trading with nano lot, your stress level will not rise. If you are starting with 100 units then you are only at 1% risk.
The micro-lot starts with the amount of 1000 units. The pip value of the Micro lot is 0.1. So, the base currency will be 1000 units.
Suppose, you are ready to open a position of EUR/USD. So, you can trade 1000 units of the base currency. Here, the EUR is the base currency and traders can buy or sell 1000 units.
A micro lot is suitable for those traders, who want to open a trade position with higher leverage. It is the smallest amount in the forex trading like nano lot.
Those who own the amount of $200-$500, can be traded with a micro lot.
Trading with a micro lot will give you the facility to trade without heavy leverage. This is also convenient for those traders who followed the money management rules.
At the same time, a micro account is also helpful to know the effectiveness of Forex brokers and traders.
As we all know, a micro lot is a 1/10th of the mini lot and 1/100th of the regular lot. It can be described like this that one mini lot equals to 10 micro lots and 100 micro lots equal to 1 regular lot.
Mini lot in Forex is suitable for those traders who are new in the trading business or want to start trading.
By using this lot, they try to enter into the trading market to learn how to trade. This mini lot is worth $1 (each pip value).
In the mini lot, price moves in a very small amount. Mini lot starts with the amount of $10,000 units.
Mini account or Forex mini lot is sometimes wise for large investors who do not want to invest their whole money in one trading market. This is about “Putting all eggs in one basket”.
You can trade with a mini lot if your trading account owns $2000.
It is the regular lot size in the Forex trading marketplace, where traders can trade with 1000 units in the micro lot and 10,000 units in the mini lot. In the standard lot, traders can trade with 100,000 units of the base currency.
Here, $10 changes instantly with just 1 pip movement.
It is recommended by most of the professional traders that if your account is worth $25,000 or more, then you can trade with a standard lot.
Importance Of A Smaller Lot Size
Generally speaking, Forex lot size will be offered by your preferable broker. You have to choose your lot size depending on how much money you want to invest in your trading account.
Additionally, you have to determine your ideal trading position size.
However, it is wise to start with a smaller lot size. Because small lot size will help you to survive in this trading market for a long time.
Here is the importance of trading with a smaller lot size:

- Novice traders can understand their own trading abilities.
- Traders who cannot afford to trade with larger sizes.

A demo account could be beneficial for traders before investing the real amount in the trading marketplace.
On the other hand, there is no guarantee that after practicing with a demo account, you will able to avoid your monetary risk. Anything can happen in the Forex market.
It is true that practice through a demo account will help you to know more about trading.
Suppose, you want to trade with a larger amount after winning a few trades. In that time, if the trade falls off then the situation will discourage you to open a new position.
You can go with a bigger lot whenever you want. But, a small lot will give you the confidence to start with a bigger one.
Success in trading overall depends on the right strategy, and also the flexibility. You can consider it as a key to effective or right trading.
