Recognising the Significance of Forex Market Liquidity

The practice of trading in foreign exchange has ancient roots, with the first recorded use of money dating back to Talmudic literature. In historical contexts, individuals known as “money changers” assisted others in converting their currency into another in exchange for a fee.

Over time, the global economy has evolved to the extent that there are now 180 distinct currencies in circulation. The trading and transactions involving these numerous currencies collectively drive the forex market, establishing it as the most liquid market globally.

What Is Meant in Liquidity?

In the context of the forex market, liquidity refers to the ease and speed with which an asset, including currencies, can be bought, sold, or converted into cash at stable prices. All financial institutions, including brokers, rely on sustainable liquidity. Whether dealing with financial assets like stocks or tangible assets like real estate, the concept of liquidity plays a pivotal role in determining market dynamics.

High liquidity in an asset allows for quick and efficient transactions, enabling buyers to acquire the asset at its actual value and receive it promptly. In trading, liquidity is measured by the volume of trades or pending trades, which reflects the balance between supply and demand. When liquidity is high, it becomes easier to find buyers or sellers, facilitating smoother transactions. Conversely, market illiquidity occurs when there is a lack of participants, making it challenging to complete transactions.

Understanding the importance of liquidity in the foreign exchange (forex) market is crucial for investors. Liquidity directly impacts the overall stability of the market and can lower risks for traders. A liquid market attracts more participants, creating favourable conditions. This means sellers do not need to lower prices to attract buyers, and bidders do not have to pay more to acquire the assets they desire.

Moreover, liquidity influences the spread offered by brokers or trading platforms. A highly liquid market tends to have a narrower bid-offer spread, while an illiquid market usually exhibits a broader spread. Recognising the liquidity profile of brokerages is essential for traders seeking to use the forex market effectively.

Signs To Distinguish Liquid from Illiquid Brokerages

Distinguishing between liquid and illiquid brokerages involves recognising specific signs. In an illiquid market, buying and selling volume can fluctuate significantly, leading to unpredictable and erratic price movements. Conversely, a liquid market, often called a deep or smooth market, experiences minimal price fluctuations, providing a more stable environment for traders. Successful risk management for most traders necessitates operating within a liquid market. Here are some key indicators that can help identify a healthy market:

  • Gaps: Forex gaps can manifest when significant news, such as interest rate announcements, impacts the market. These gaps are more prevalent in the US on Sunday afternoons at the beginning of the week. Unlike equity markets that trade 24 hours a day with fewer gaps, markets operating for only part of the day, like the US equity market or Futures Exchange, tend to be more volatile due to overnight news, resulting in thinner markets.
  • Indicators: Brokers commonly offer a “volume” option on the chart, allowing traders to evaluate the liquidity of FX pairs. Traders can analyse liquidity indicators by examining the bars on the volume chart, with each volume bar representing the amount of trading activity during a specific period. It is essential to note that brokers typically display their liquidity data, not the overall forex market liquidity. Nevertheless, depending on the broker’s size, using their liquidity as a reference can accurately represent the retail market.
  • Timing: Forex liquidity can fluctuate throughout the trading day, requiring short-term traders to remain aware of these changes. Significant support and resistance levels often occur during the Asian Session and other less busy hours. In contrast, breakouts and substantial percentage changes are more likely to occur during the London and US sessions, which are crucial active market periods. Approximately fifty per cent of the day’s total volume occurs during the United States (and Europe’s and London’s) morning session, with around 20% of the total volume occurring during the less active US afternoon, except for FOMC announcements.

What is Influencing Liquidity?

Factors influencing liquidity in the financial markets should be well understood by retail traders. Spreads and the volatility of currency pairs serve as key indicators of market liquidity. In highly liquid markets, constant shifts in price quotes and movements are typical, with brief declines being commonplace. On the contrary, low-liquid markets exhibit sharp price swings and frequent revisions in quotations.

The quantity of traded currency pairings is another crucial determinant of FX liquidity. The most actively traded pairings include EUR/USD, GBP/USD, USD/JPY, USD/CAD, USD/CHF, and AUD/USD, where the USD holds dominance, accounting for 90% of all FX transactions. Notably, the EUR/USD spread is the narrowest among these currency pairs.

Understanding that the foreign exchange market operates 24/7 is essential for traders. Volatility and liquidity levels can vary based on trading sessions held during business days. Asia’s key financial hubs, such as Japan, Australia, and China, don’t operate simultaneously, contributing to fluctuations. The American and European markets witness heightened activity, with liquidity tapering towards the close of the European day.

Trading in thin markets during these periods may pose challenges due to narrow price ranges and occasional price outliers. This consideration is paramount when evaluating potential investments, emphasising the need for traders to be mindful of market conditions.

Basic Tasks of LPs and Ways of Connecting Them

LPs play a crucial role in financial markets by establishing pools for funds, banks, and financial institutions to offer quotes and data to more minor market participants. These pools enhance market efficiency by reducing spreads and mitigating price gaps or market slippage risks.

Categorically, liquidity providers are classified into Tier 1 and Tier 2. Tier 1 providers grant access to major financial institutions, while Tier 2 providers offer access to one or more banks. Prime-of-Prime (PoP) liquidity providers manage comprehensive pools that encompass Over-the-Counter players and dark pools, making them significant entities in the FX market.

For a brokerage firm seeking to enhance its access to a diverse array of funds and connect with an LP, the following steps are typically involved:

Research and Selection

Conduct thorough research to identify a reputable provider from the various companies in the Forex market. This selection is critical to establishing a reliable and effective partnership.

Application Submission

Complete and submit an application form to the chosen liquidity provider. During this process, details of the partnership, including any fees associated with trades, should be discussed and agreed upon.

Aggregation and Connectivity

Choose the most suitable aggregation service, such as PrimeXM or OneZero, and select the relevant liquidity venues, which may include platforms like MetaTrader 4/5, DX Trade, or B2Trader. Connecting with these desired pools enhances the brokerage’s access to a broad range of available funds.

By following these steps, brokerage firms can effectively connect with liquidity providers, expanding their access to liquidity pools and fostering a more efficient trading environment for their clients.

Instructions for Measuring Liquidity

Measuring market liquidity lacks a universally accepted metric, but specific indicators can be employed to estimate the depth of a market. Here are some tips:

Share Turnover in Stock Markets

In stock markets, share turnover is commonly used to gauge liquidity. This metric is calculated by dividing the number of positions traded during a specific period by the average number of positions held during the same period. A higher share turnover ratio theoretically indicates a more liquid market.

Trading Volume

Trading volume is a crucial metric that reveals how frequently a specific asset is traded within a given time frame. Low volume suggests fewer counterparts, while high volume indicates greater liquidity and robust performance, especially in Forex markets.

Bid/Ask Spread

The bid/ask spread, representing the difference between the prices at which buyers and sellers are willing to transact, serves as another indicator of market liquidity. The bid/ask spread in liquid markets tends to narrow, while in illiquid markets, it widens. A narrower spread implies lower transaction fees when trading, making it a valuable measure of liquidity.

While there’s no one-size-fits-all metric, combining these indicators can provide a more comprehensive understanding of market liquidity. Traders and investors often analyse these factors collectively to assess a market’s overall health and depth, helping them make informed decisions in their trading strategies.

Final Remarks

Staying informed with regular market updates provides valuable insights into the factors affecting volatility and liquidity. This awareness is instrumental in making informed decisions that can contribute to successful and profitable transactions.
