How much is one lot in forex trading? Basic knowledge that beginners must understand

Why is it important to understand the concept of “lot”?

In forex trading, you will often hear the term “lot.” Simply put, a lot is a unit of trading volume, representing the amount of currency involved in a single trade. If you don’t understand this concept, you won’t be able to place orders.

In the forex market, trading size matters. Currency price fluctuations are usually very small, with a single pip movement often only a few thousandths of a percent. To profit from these tiny movements, traders need to trade a sufficiently large amount of currency to see significant profit or loss. This is why the concept of “lot” is crucial.

How many currency units are in one lot?

In forex trading, 1 standard lot (1 lot) equals 100,000 units of the base currency.

For example:

• The contract value of 1 standard lot of EUR/USD = 100,000 euros
• If you trade 1 standard lot, and the EUR/USD exchange rate rises from 1.38869 to 1.38879 (a 1 pip increase), you will profit $10

This is the pip value mechanism in the forex market. The same price movement results in larger profits or losses with larger trading volumes.

What is the difference between different lot sizes?

Since forex trading requires large capital, trading platforms usually offer multiple lot size options to accommodate investors with different capital scales:

The conversion relationships between these lot sizes are:

1 micro lot = 0.1 mini lot = 0.01 standard lot

For small investors, mini and micro lots are good ways to reduce risk. You can trade with less capital while gaining experience.

How does leverage enable small accounts to make large trades?

The reason retail forex traders can trade large positions is due to leverage trading.

Imagine: you have $1,000 but want to trade a $100,000 EUR/USD position. This seems impossible, but leverage makes it possible. Trading platforms offer 100x leverage (100:1), meaning you only need to deposit $1,000 as “margin” to control a $100,000 trade size.

What is the role of margin?

Margin is not a trading fee but a deposit. When your position incurs a loss, the loss is deducted from the margin. If the loss exceeds the margin balance (e.g., over $1,000), the platform will automatically close the position to prevent account blow-up.

Leverage multiples depend on the trading platform you choose. Mainstream forex platforms typically offer leverage options from 50x to 200x. Beginners should start with lower leverage (such as 10x or 20x) and, after gaining enough trading experience and risk management skills, consider increasing leverage.

Practical tips

After understanding lot sizes and leverage, here are some practical tips:

• Choose the appropriate lot size based on your account funds (don’t start with a standard lot)
• Higher leverage means higher risk; opt for conservative leverage ratios
• Set stop-loss and take-profit levels, strictly manage each trade’s risk exposure
• Beginners should practice with mini or micro lots, and only increase position sizes after developing a stable trading strategy

Mastering these basics will help you truly understand how forex trading works.
