What exactly is one lot in forex trading? An in-depth explanation of pip value and lot size relationship

In forex trading, the most common question beginners ask is “What is one lot?” Simply put, one lot is the basic unit of measurement for a trade, representing a specific size of a trading contract. Understanding this concept is crucial for managing trading size effectively.

How Much Currency Is in One Lot? Understanding Forex Trading Units

In forex trading, a “lot” measures the size of a trade. One standard lot equals 100,000 units of the base currency. For example, in EUR/USD, one standard lot is worth 100,000 euros.

Why do traders need such large transactions? Because in the forex market, price movements are measured in pips—a tiny percentage change in the exchange rate between two currencies. If a trader only holds a small amount of currency, these small price fluctuations are unlikely to generate significant profit or loss. For this reason, traders often trade large amounts of currency to amplify the gains or losses from small price movements.

For example, in a standard lot of EUR/USD, when the exchange rate moves from 1.38869 to 1.38879 (a 1 pip increase), the account gains or loses $10. This illustrates the basic operation of a standard lot.

From Standard Lots to Mini and Micro Lots: Comparing Pip Values

Since forex trading requires substantial capital, most trading platforms offer various lot sizes, allowing investors to participate with less capital. Therefore, mini lots, micro lots, and other sizes have been introduced:

1 micro lot = 0.1 mini lot = 0.01 standard lot

This conversion helps traders with different capital sizes adjust their trading volume flexibly. The table below shows the pip value for different lot sizes across major currency pairs:

For example, if you trade 0.01 lots (micro lot) in EUR/USD, a 1 pip move results in a $0.10 change in your account, not $10. This allows small investors to participate in the forex market.

Platforms like Mitrade, a forex margin broker, offer up to 200x leverage and allow trading as low as 0.01 lots, providing more flexibility for traders with limited capital.

Why Use Leverage? Margin and Risk Management

Since one lot requires 100,000 units of the base currency, how can ordinary investors access such large trading amounts? The answer is leverage.

Think of a forex broker as a bank: they are willing to lend you $100,000 for trading, provided you deposit a margin as collateral. For example, if you want to trade a $100,000 position but only have $1,000 in your account, the broker allows you to control the entire position with that $1,000. This is a 100:1 leverage ratio, requiring a 1% margin.

It’s important to note that this $1,000 is not a fee but a deposit. Its purpose is to protect both the broker and the trader. If your losses reach or exceed the margin amount, the broker will automatically close your position to prevent further losses. Therefore, margin is a key risk management tool—it limits your maximum loss.

While leverage can amplify profits, it also magnifies losses. That’s why understanding lot sizes, learning to adjust trade volumes, and using leverage responsibly are essential for every forex trader. In future trading lessons, we will continue to explore various aspects of leveraged trading.
