In the dynamic field of financial markets, every detail is important. One of the important factors is the gearbox, a concept often neglected by beginners, but essential for success in trading. Find out what the foreign currency spread, how it is calculated, the existing types and its impact on financial transactions is calculated
What is the diffusion of foreign currency?
The foreign currency is the difference between the purchase price (request) and the sale price (bid) of a pair of currencies. This difference is expressed in the pips and is an implicit cost for traders. For example, if EUR/USD has a purchase price of 1,1050 and a sales price of 1,1048, the spread is 2 pips. This cost is borne by the trader when a position opens and must be recovered from favorable movements on the financial market, in order to carry out a profit.
Types of spreads in foreign currency
The spread is an indirect cost supported by each merchant and the type of spreads chosen can significantly influence the performance of the investment portfolio.
Fixed fixed gearbox resolves
Fixed diffusion is that type of diffusion that remains constantly independently of market conditions. This means that the difference between the purchase price (ASH) and sales (BID) is predetermined by the broker and does not change even during the increase in volatility periods.
The advantages of fixed diffusion
- high predictability: The traders know exactly how much they will pay for each transaction;
- Ideal for beginners: The new trading can avoid the surprises caused by sudden increase in costs;
- Useful for chiciting and daytime trading strategieswhere each PIP matters.
Disadvantages of fixed diffusion
- In general, the fixed spreads are greater than the variable in normal market conditions;
- The execution of the orders can be delayed in times of high volatility, when the broker requires re-work.
Who uses fixed spreads?
This type of diffusion is commonly found in the platforms offered by market makers, which act as counterparts in the transaction. They set the diffusion according to their business model and the risk they take.
Variable distribution (dynamic) in foreign currency
Unlike the fixed spread, the variable spread changes in real time, depending on the market conditions. This currency graph reflects the offer and demand for that moment for a pair of currencies.
The advantages of variable spreads
- smaller in normal conditions: In periods with low volatility and high liquidity, the diffusion can even be 0.1 pips;
- transparency: The price displayed faithfully reflects the conditions of the interbanca market;
- Ideal for advanced traderswhich can benefit from small fluctuations to maximize winnings.
Variable diffusion disadvantages
- unpredictability: During important economic news or in volatile markets, spreads can increase significantly;
- Unexpected costs are higher For automatic strategies or for short -term open positions.
Who uses variable spreads?
The variable spreads are mainly found in ECN and STP (electronic / straight communication network through processing), which directly connects the interbank market, without intervening in the price setting.
Comparison of fixed spreads vs. variables
| Characteristic | Distribute the correction | Variable diffusion |
|---|---|---|
| Stability | Constant | Changes according to the market |
| Cost in normal conditions | Slightly higher | Usually smaller |
| Risk in volatile periods | Reduced (but with re-cauto) | Increase (but quick execution) |
| Suitable for | Beginners, simple strategies | Advanced traders, shrewd |
| Typical brokere | Market Maker | ECN / STP |
What kind of diffusion is most suitable for you?
The choice between a fixed and variable spread must be based on:
- Your trading style: If you prefer rare stability and transactions, the fixed spread is a good choice. If you are a break or it is often, the variable spread can be more efficient;
- Your trading program: If exchanged in the top hours (London, New York), you can take advantage of the small spreads offered by the variable version;
- Your risk tolerance: The traders who prefer complete control of costs will feel more comfortable with fixed spreads.

How to calculate the spread of changes?
The calculation of the diffusion is simple:
Spread = Price ask – Price offer
For example, if EUR/USD has a 1,1050 request price and an offer price of 1,1048:
Spread = 1,1050 – 1,1048 = 0.0002 = 2 pips
The monetary value of a pip depends on the volume of the transaction. For a standard lot (100,000 units), a pip is worth about $ 10. Therefore, a 2 pips spread indicates a cost of $ 20 for a standard batch transaction.
The impact of the diffusion on financial transactions
In Forex Exchange (Forex), each PIP is important. Even if the spread looks like a small technical detail, its impact on financial services is important. The spread is, in fact, an invisible cost that each investor pays when he opens a transaction. Here’s how profitability, risk and trading strategies influence the diffusion of changes.
Increases the total cost of the transaction
That you are exchanging a standard, mini or micro lotto, the diffusion directly affects the market on the market. The greater the spread, the greater the distance in which the price must travel in the favorable direction for the trader to reach the break-andven. For example, with a standard lot of 100,000 units and 1 pip of about 10 USD, a diffusion = 3 pips. The cost becomes $ 30 at the opening of a single position.
Reduce the profit margin
For short -term trading strategies (shrewd, one -day trading), the spread can be a significant percentage of potential profit. The shorter the lowest positions and profits, the stronger the cost of the diffusion has a stronger impact on the final result. If the strategy follows a 5 pips profit and the spread is 2 pips, practically 40% of the profit is consumed by the diffusion.
Increases risk in the market
In moments with high volatility, such as launching important economic indicators or geopolitical events, spreads can grow abruptly, which leads to:
- execution of orders at weaker prices;
- Premature activation of the loss of stop;
- Opening positions with greater loss than expected.
How the impact of diffusion varies according to the trading style
Shrewd
The traders of the scalp perform dozens or hundreds of transactions per day, following profits of a few pips. In this context, the spread is a critical cost and a high spread can transform the investment strategy into a non -profitable.
One day trading
For the daytime trader, the diffusion is an important factor, but the impact has slightly decreased compared to the chise. However, a strategy with a target of 20-30 pips can become much less attractive if the diffusion is 4-5 pips.
Trading Swing and long -term trading
In the long term, the spread has a relatively less impact on total profit, since the positions are open at larger intervals and the price fluctuations are higher. However, the spread continues to count in the calculation of the net yield.

Other indirect effects of diffusion
- affects the calculation of the risk reconditioning relationship -Stares must adapt the loss of arrest and obtain profits to compensate for the initial cost of the spread, which can change the risk structure in the transaction;
- Influence the choice of the broker -The broker that offers smaller spreads is often preferred, even if they receive fixed commissions. The choice of the correct platform can significantly reduce trading costs over time;
- Changes the behavior of investments in relation to macroeconomic factors -The diffusion can be widely expanded before and after events such as ads of interest or unemployment relationships. Many traders choose to avoid transactions in such moments, in order not to support volatile spreads.
Factors that influence the diffusion
- the liquidity of the market: The main currency pairs, such as EUR/USD or USD/Jpy, have smaller spread due to the large volume of transactions;
- Volatility: Economic or political events can increase volatility, expanding spreads;
- transaction time: The spreads tend to be smaller during active trading sessions, such as London or New York;
- The type of broker: ECN brokers offer smaller spreads, but can charge further commissions.
Strategies for effective dissemination management
- Choose the right pairs of currencies: Concentrate on couples with small spreads and high liquidity;
- Negotiation in the top hours: Avoid transactions outside the hours of maximum activity to benefit from smaller spreads;
- Use of limit orders: facilitates entry into the market at the desired prices, avoiding the additional costs of the spread;
- Monitoring of economic events: Consider events that can affect volatility and, implicitly, spreads.
Understanding and managing changes is essential for success in trading. This apparently lower cost can have a significant impact on profitability, especially in short -term strategies. By choosing the right pairs of currencies, trading in optimal times and using appropriate strategies, traders can minimize the impact of the spread and can maximize the profit potential.
