Fixed and Floating Spread: Which One Should a Trader Choose?

Evgeny Arhipov

Minimizing trading costs is a natural desire for any participant in financial markets, and it’s no surprise that the size of the spread is one of the most important factors for traders when choosing a brokerage company, and for brokers themselves, it’s a powerful competitive advantage and a lever for attracting clients.

Following this logic, it can be assumed that the lower the broker’s spread mark for a particular financial instrument, the more beneficial the trading will be for its clients. However, in practice, this is not always true. Moreover, a large part of major brokerage companies offers both fixed and floating spreads, the size of which is unlimited and not regulated anywhere. And they consider this one of their competitive advantages in the market.

Is it worth for a trader to look for a trick in narrow fixed spreads? Is there a reason to be wary of a floating spread? And which of these types of service charges is more profitable for the brokers themselves? We will discuss this and other characteristics of calculating spreads on financial markets further.

Fixed Spread on Forex

Before starting a detailed discussion about the spread, it’s useful to recall what it actually represents.

Spread is charged for each trader transaction regardless of its outcome and is a form of payment for intermediary services on the financial market, i.e., the broker’s pure income. Mathematically, the spread is the difference between the most favorable buying and selling prices of the same financial instrument.

Thus, the spread for each instrument at any given time should change depending on current market quotes.

A broker who fixes the spread for a certain period of time at the same level does so artificially. It is obvious that the size of the fixed spread has no direct relation to the volatility of the instrument.

Floating Spread on the Market

The floating spread on the foreign exchange and other financial markets is determined solely by the market situation and does not involve any external intervention. A trader using a floating spread pays for each transaction an amount equal to the difference between the bid and ask prices of the asset at the time of the transaction. Thus, no one, including the broker, can predefine the size of this fee or guarantee the hypothetical profitability of a particular transaction.

Pros and Cons of Different Types of Spreads

Fixed and Floating Spread: Which One Should a Trader Choose?

Using a low and importantly known spread gives a trader an advantage and increases the productivity of their market activity. However, it is important to understand that no broker will work against their own interests and significantly reduce their own profit.

In the case of a significant increase in the gap between the best Bid and Ask prices, the size of the fixed spread can also be increased, i.e., fixed at a new level. And during high volatility of the market, it may expand up to several hundred points at once. The very fact of the broker’s ability to intervene in determining the spread size implies not only its reduction to attract clients, but also a significant increase compared to the objective market situation to boost their own profits.

On the other hand, an unregulated floating spread can potentially be both lower and significantly higher than a fixed one at different times, adding an additional element of nervousness to the already stressful work of a trader.

However, it can be reasonably assumed that the broker does not influence not only the size of the spread, but also other deal parameters, including quotes. This means that traders are indeed interacting with other market participants, not with the company itself.

Rules for Safe Trading with Fixed Spreads

Of course, the artificial nature of the concept of a fixed spread is not a reason to refuse the opportunity to plan and reduce your trading costs, however, before taking advantage of a favorable offer from a broker, make sure that:

  • Minimum spreads of 0.2, 0.5, or 1 pt. are offered not for all currency pairs, but only for the most liquid ones. Otherwise, the question arises: at whose expense does the broker make its profit and does it actually send client transactions to the market at all.
  • Fixed spreads are offered only for deals processed by the dealer. Because working on the direct interbank market and processing transactions without going through the Dealing Desk excludes the possibility of any manipulations with deal parameters, including the spread size.
  • The company does not give a 100% guarantee of maintaining a fixed spread at the same level and clearly informs clients about the possibility and conditions of its change. Other statements would mean the broker’s willingness to suffer losses with every significant jump in volatility or liquidity of the market, which contradicts both simple logic and business principles, and therefore cannot be true.

Conclusion

It is not difficult to notice that the type of spread itself is not a guarantee of the broker’s reliability or the profitability of working with them – both fixed and floating spreads have their own advantages and disadvantages. However, careful study of the companies’ offers and understanding that in terms of spreads, less is not always better will certainly help you optimize the costs of each trade and increase the overall safety of your market work.
