what is a forex lot?

If you have taken your first steps in the foreign exchange market and you have fully understood what is a forex lot and how it works the next thing to know are the basic terms used in this market.

In this article, we will explain in a simple way what is a lot, the types that exist and how they are calculated.

What is batch simple explanation

When buying and selling any goods or products, all parties involved (buyer and seller) must use the same Units of measurement.

Examples of different units of measurement include kilograms, tens, meters, hands, mini hands, etc.

All market participants use units of measurement that always represent the same quantity, the same weight, or the same volume at any place or time.

Lot is the unit of measurement used when we talk about the Forex market.

A lot represents a standardized unit for buying and selling in the foreign exchange market. In other words, people who participate in this market do so by trading any amount of currency they choose. The term “lot” means 100,000 units of the selected currency or currency symbol or currency.

Let’s look at an example of the US dollar (USD) and the euro (EUR), since they are the most exchanged currencies:

  • 10 lots of USD are equivalent to 1,000,000.00 USD because each lot consists of 100,000 units of the selected currency 10 lots of USD = 10 x 100,000 = 1 million.
  • 2 lots of Euros equals 200,000 Euros. 2 lots of EUR = 2 x 100,000 = 200,000 EUR

What is batch for?

Transactions in the foreign exchange market are carried out by buying and selling a certain number of hands

For example: We buy 3 lots of USD/EUR which is equivalent to buying 300,000 USD.

Therefore, the amount we buy or sell will define Our scale of operation.

The size of the operation is crucial when trading because it determines Risks in our business: How much we lose if the price moves against us. It will also tell us how much we will gain if it goes in our favor, so we will determine the risk/reward of the trade.

Forex lot type

In Forex, a lot always refers to 100,000 units of a currency or currency, just as a dozen always refers to 12 units

However, to make it easier for more people to participate in the market, brokers offer the possibility to invest or exchange smaller amounts per lot. Get smaller quantities by breaking a lot into smaller parts:

  • Mini hands: Represents a tenth or 10% of a lot, corresponding to 10,000 units of coin.
  • miniature hands: Represents 1% of the lot size, corresponding to 1,000 units of coins.
  • Nano batch: it is specially offered by some brokers and can correspond to 100 or even 10 currency units, depending on the investment platform used.
