Therefore, sums differ from standard to nano lots and are based on the abilities and desire to purchase or sell on a particular trade.

To find out what is a lot size in forex, we need to delve into some detail and discuss their existing variety.

Standard lot size Forex

To begin with, there is a standard option equal to 100,000 units of the main currency in the pair. Thus, if we consider the EUR/USD pair, the euro here serves as a base, and therefore, the standard size is equivalent to 100,000 euros.

Let us consider the following example for a better understanding of lot sizes in forex:

  • Imagine you are going to work with the USD/EUR option.
  • If you select a standard for it, the purchase or sale occurs for an asset worth $100,000.
  • Therefore, all the price fluctuations will have a significant impact on your balance.
  • For instance, in a USD-based pair, a pip would be approximately equal to $10. Thus, a 20-pip move will be a $200 profit or loss for you.

Such lot size in forex trading combined with small deposits will lead to the quick growth of your budget or its complete drain as big volatility is observed here. As the risks are high, only experienced and qualified professionals for whom this is the main work can be recommended lot size forex that belongs to this group.

The next possible forex trading lot size is mini. It is ten times less than the previous one. Consider an example:

  • For the USD/EUR option, it is $10,000.
  • Such size provides less impact on your budget in case of any unexpected changes.
  • A pip is equal to $1 approximately.

Thus, if we talk about forex risk management lot size, this option gives less profit but is generally favorable and safer. The risk of large drops with negative consequences of the transaction becomes less pronounced.

Nevertheless, even for this option, one must have enough funds in case of some unsuccessful transactions. Market fluctuations must be taken into account in risk calculator forex to solve all probable problems.

Micro and nano lot options for those who do not like to risk

And this was not the end while answering the question of what is lot size in forex. So, there are even smaller options. Micro lots correspond to one-tenth of their mini counterpart. Therefore, it will be equal to 1,000 units of the pair base, and one pip will correspond to only $0.10 while trading.

In addition, there is a nano lot, which means 100 units of the base currency or one-tenth of a micro-lot size. A one-pip move for a USD-based pair is only one cent.

According to the opinion of experienced people, beginners should start from these two options even if they are aware of what is lot size forex and the nuances of their possible types. It is a good way to reduce risks to a sensible level.

The one probable inconvenience is the fact that not all brokers work with these options. Thus, you will need some time to find suitable options. So, manage your views on time and risks, and then make a decision based on all the available information.

Max lot size forex

  • The maximum will be shown in a separate line.
  • In the next step, you have to multiply these two numbers, and the resulting number will show you the highest lot here.

Min lot size forex

The minimum trade is also designated in the same table. If for the above-mentioned example, it will be ten or another number of times less, the minimum purchase will be calculated accordingly by multiplying the numbers.

These calculations are not very difficult, but it still takes time to get used to them and start doing them without thinking or hesitation. Do practice a little bit before proceeding to the next steps and evaluations of the positions.

How to determine lot size in Forex?

After we have learned what are lot sizes in forex, we need to solve the next issue, namely, which one of them to choose. This challenging decision depends on your aims, the desirable income, and your attitude toward forex risk. Thus, professional experienced traders generally prefer standard options as they are fully aware of what is at stake and how to deal with some difficulties.

For beginners and those who appreciate trading as a hobby, a mini-account seems to be the first choice. Still, it is recommended to follow the basic rules of money management and not make transactions that exceed 10% of your deposit.

Before answering the question of what is the highest lot size in forex trading, a beginner should start with micro lots or cent accounts. This allows trading with real money, learning, and gaining experience, while risks stay limited. The nano account is also suitable for novice traders who would like to know how to measure lot size. However, they can easily get bored with such minimal transactions and lose interest in trading at all.

No matter what forex position size you select, it is always advisable to follow several basic tips.

Tip 1

Before you proceed with any forex lot size calculator, it is better to consider acceptable risks. This value is individual and must be set according to your goals, preferences, and financial situation. Thus, for someone, a risk of 1% is acceptable, while others allow 3% or 5%. Select one system for evaluation of risks among the existing options and follow it constantly.

Tip 2

While you calculate lot size forex, the risk indicator shows the part of your deposit that you will lose in case of an unsuccessful operation. The basic recommendation is to operate with 1-5% of your deposit. Thus, even when you encounter a series of losses, you will still have the opportunity to win your money back and get a profit. Otherwise, no matter what lot size trading you select, the chances to recover tend to diminish.

Tip 3

If you do not want to utilize the forex lot calculator, there is a possibility to do the same calculations by yourself. The following steps are required:

  1. First of all, you have to determine your individual parameters. For instance, let it be a $1,000 deposit size with 1% acceptable risk and the stop level at 50 points.
  2. Risk evaluation will be the following: $1,000/100*1. And it is $10.
  3. To restrict the losses to $10 per trade, 50 pips must match that amount.
  4. From here, the cost of 1 point is calculated: $10/50=$0.2.
  5. If a market price of 1 pip is equal to 10 cents (0.1$), the lot value appears to be 0.2*0.1$, or 0.02.

Such lot size calculator forex reveals that it is advisable to utilize micro-lots. Following this general scheme, you can type your own numbers and percentages and calculate the results.
