As the most liquid market in the world, Forex boasts a daily trading volume that exceeds
approximately $6 trillion, presenting massive opportunities for traders and investors looking
to profit from currency fluctuations. Having a firm grasp on the concept of liquidity will
stand every Forex trader in good stead for navigating the markets like a pro.
Liquidity in a Nutshell
In the Forex world, liquidity refers to the ease with which a currency pair can be bought or
sold without significantly impacting its exchange rate.
When a currency can be traded with minimal price changes, it is considered a liquid
currency. On the other hand, if trading a currency pair results in significant price swings, it is
deemed to have low liquidity.
How to Determine Low and High Liquidity
1. Trading Volume
One of the main indicators of liquidity is trading volume. Currencies with high trading
volumes tend to have greater liquidity. Major currency pairs, like EUR/USD, GBP/USD, and
USD/JPY typically have high liquidity due to their popularity and high trading volumes.
Traders can easily buy and sell these pairs without causing significant price fluctuations.
2. Tight Bid-Ask Spreads
The bid-ask spread is the difference between the buying (bid) and selling (ask) prices of a
currency pair. Liquid currency pairs usually have narrow spreads, which means that there’s a
minimal difference between the two prices.
A tight spread indicates that there’s a healthy level of trading activity in that currency pair,
contributing to its liquidity.
3. Market Depth
Market depth is a measure of the number of buy and sell orders available at different price
levels. In liquid currency pairs, you will find a ‘deep market’ with a significant number of buy
and sell orders at various price points. This depth allows traders to execute large orders
without causing major price disruptions.
Know your risks
While trading in highly liquid currency pairs can be exciting as it presents many advantages,
it’s also important to be aware of the potential risks at play with Forex liquidity.
• In extremely volatile market conditions or during major economic events, even
highly liquid currency pairs can experience what’s known as price slippage . Price
slippage is when the executed trade is at a different price than expected because of
rapid market movements. In situations like this, traders should use stop-loss orders
to limit potential losses.
• It’s possible for liquidity to vary throughout the trading day. During times of low
liquidity, spreads may widen significantly and this can lead to higher trading costs.
• While trading in highly liquid currency pairs is generally more accessible, some
traders may find it difficult to profit from small price movements. In contrast, less
liquid currency pairs may offer more significant price swings – but they also come
with higher risks.
• Trading in extremely illiquid currency pairs can be risky as it may be challenging to
execute trades at your desired price levels. It’s also possible for traders to encounter
larger spreads and higher trading costs.
