Liquidity in Forex Trading: Everything You Need to Know

When you enter the world of forex trading, one term you’ll hear often is “liquidity forex” or “liquidity.” However, many traders still don’t fully understand how important liquidity is to their trading strategies. In this article, we’ll explain in detail what liquidity is in the forex market so you can make the most of it.

What is liquidity and why is it important for traders?

Fundamentally, liquidity is the ability to convert an asset or currency into cash quickly and easily without accepting a significantly lower price than the current market rate.

The more liquid an asset is, the easier it is to buy and sell. Cash is the most liquid asset, while real estate or artwork are much less liquid.

In the forex market, which operates 24 hours a day, 5 days a week, the liquidity of each currency pair varies. Major pairs like EUR/USD have high liquidity because they trade billions of dollars daily, whereas emerging pairs may have lower trading volumes.

The difference between high and low liquidity

Highly liquid forex pairs

EUR/USD: This is the most traded pair in the world, representing two of the largest economies. Continuous trading during European and US sessions ensures high liquidity throughout the day.

USD/JPY: The second most traded pair, favored for its narrow spreads and stable price movements.

GBP/USD: Very high liquidity, especially when London and New York sessions overlap.

USD/CHF: The Swiss franc is considered a “safe haven,” and this pair has high liquidity, especially during economic crises.

AUD/USD: High liquidity during the Asian session, as Australia is a major commodity exporter.

Less liquid forex pairs

USD/SEK: Despite Sweden’s strong economy, the Swedish krona isn’t as popular in international markets.

GBP/ZAR: The South African rand is highly volatile and less liquid, leading to wider spreads.

USD/TRY: The Turkish lira has experienced economic instability, resulting in low liquidity and wide spreads.

EUR/HUF: This pair has relatively low liquidity; the Hungarian forint isn’t widely traded.

How liquidity affects your trading costs

Before depositing funds, you should understand how liquidity impacts your profits and losses.

Bid-Ask Spread: When viewing a currency pair’s price, you’ll see a “buy” (ask) and “sell” (bid) price. The difference is called the spread, which is a cost you pay to enter a trade.

High liquidity pairs like EUR/USD may have spreads as narrow as 1-2 pips, while low liquidity pairs can have spreads of 10-20 pips or more.

This means: If you buy EUR/USD at 1.0850 with a 2-pip spread, the price must rise above 1.0852 for you to profit. Conversely, if you buy a low liquidity pair with a 15-pip spread, the price must increase by more than 15 pips to break even.

Slippage: Low liquidity can lead to slippage, where your order executes at a different price than expected. For example, placing a buy order at 1.2000 might fill at 1.2010 — a 10-pip slippage.

Large orders: If you want to trade large volumes, low liquidity markets may not support your order size, causing prices to move before your position is fully filled.

Best times to trade high-liquidity forex

Liquidity varies throughout the day, depending on market sessions.

Peak liquidity: When the London (08:00 GMT) and New York (13:00 GMT) sessions overlap, trading volume is highest, and spreads are narrowest.

Lower liquidity: During the Asian session after the New York close or during the “lull” periods between sessions, spreads widen, and price movements can be jumpy.

How to measure and identify liquidity

Check the Bid-Ask Spread

A narrow spread indicates high liquidity; a wide spread suggests low liquidity.

Monitor trading volume

High trading volume signals high liquidity; low volume indicates less popular markets.

Observe price movements

In high-liquidity markets, prices change smoothly without gaps. Low-liquidity markets often show gaps or sudden jumps.

Use technical indicators

Tools like Moving Averages, Bollinger Bands, or Volume Indicators can help identify liquidity conditions and suitable trading points.

Examine Market Depth

Market Depth shows the number of buy and sell orders at different prices. A deep market (many orders at various levels) indicates high liquidity.

The relationship between liquidity and volatility

Many traders confuse liquidity with volatility, but they are entirely different concepts.

Volatility refers to the magnitude of price changes. Highly volatile markets see rapid price swings up or down.

Liquidity is how easily you can buy or sell an asset when you want.

For example:

• EUR/USD: High liquidity, low to moderate volatility
• GBP/USD: High liquidity, moderate to high volatility
• USD/TRY: Low liquidity, high volatility

When liquidity drops, volatility often increases because small changes in supply and demand can cause large price swings. Conversely, high liquidity tends to dampen volatility, as many buyers and sellers absorb price movements.

Factors affecting forex liquidity

Market hours

Forex operates 24 hours, but liquidity varies by session: Asian, European, and American.

Economic news releases

Major announcements like employment data, inflation reports, or central bank decisions can spike trading volume (increase liquidity) before the release, or cause market pauses.

Market sentiment

Political uncertainty or economic crises can reduce liquidity as traders hesitate. Conversely, high confidence encourages trading and liquidity.

Seasons and holidays

Major holidays often see reduced trading activity, leading to lower liquidity.

Who provides liquidity in the forex market?

Who are the market makers providing liquidity? Several entities:

• Central Banks: They buy and sell currencies to stabilize their economies.
• Large Commercial Banks: Conduct massive currency transactions.
• Investment Institutions: Hedge funds and institutional traders that trade based on market assessments.
• Forex Brokers: Intermediaries connecting retail traders to the interbank market.
• Retail Traders: You and other individual traders collectively contribute to liquidity, albeit in smaller volumes.

Tips for beginners: choosing high-liquidity currency pairs

If you’re new to forex trading, keep these tips in mind:

1. Start with major pairs: EUR/USD, USD/JPY, GBP/USD, USD/CHF, AUD/USD are ideal for beginners due to narrow spreads, high liquidity, and manageable volatility.

2. Avoid low-liquidity pairs initially: Pairs like USD/TRY, GBP/ZAR, or EUR/HUF have wider spreads and higher volatility, making risk management more challenging.

3. Trade during high-liquidity hours: Aim to trade during the London and New York overlap for the best conditions.

4. Monitor economic calendar: Be aware of scheduled economic releases that can cause sudden liquidity shifts.

5. Use a demo account: Practice with a demo account to familiarize yourself with market movements and how liquidity impacts trading.

Summary

Liquidity in forex is a crucial factor that can determine your success or failure. High liquidity means narrow spreads, less slippage, and more stable prices. Low liquidity results in higher trading costs and increased risk.

Whether you’re a beginner or an experienced trader, understanding and selecting currency pairs with high liquidity is key to successful forex trading. Invest time in learning how liquidity works, and you’ll find yourself with a significant advantage in the markets.
