How Forex Spreads Work: A Practical Guide for New Traders
8 min read · 6/3/2026 · FXTrustIndex Editorial
Forex spreads are one of the most common trading costs. This guide explains bid vs ask, why spreads vary by pair and session, how broker models affect pricing, and practical checks traders can use when comparing brokers.
Spreads are a core part of how forex trading costs work. Even if a broker advertises “low spreads,” the real cost can change depending on the currency pair, time of day, market liquidity, and the broker’s execution model. For new traders—especially those comparing brokers from the UAE/GCC and across Asia—understanding spreads helps you read trading conditions more accurately and avoid surprises.
What is a forex spread?
In forex, each currency pair is typically shown with two prices:

- · **Bid**: the price at which you can sell the base currency (close a long or open a short).
- · **Ask**: the price at which you can buy the base currency (close a short or open a long).

The **spread** is the difference between the ask and the bid. It’s effectively the “gap” you pay to enter the market. If you place a market order, your trade usually starts with a small unrealized loss equal to the spread, because you buy at the ask and would sell back at the bid.
Why spreads exist
Read our [forex broker regulation](/regulations) for more context.
Spreads exist because liquidity providers and brokers need compensation for facilitating trades and taking on short-term inventory or execution risk. In practice, spreads are influenced by:
- · How actively a pair is traded (liquidity)
- · How many buyers and sellers are available at a given moment (depth)
- · Market volatility and uncertainty
- · The broker’s pricing and execution setup
Major, minor, and exotic pairs: why spreads differ
Not all currency pairs trade with the same intensity. As a general rule, more liquid pairs tend to have tighter spreads, while less liquid pairs tend to have wider spreads.
Major pairs
**Majors** are heavily traded and typically have deep liquidity across multiple sessions. Because many market participants are active, pricing tends to be more competitive, which often results in smaller spreads—especially during liquid hours.
Minor (cross) pairs
**Minors** (pairs that don’t include the USD) may have less liquidity than majors. Even if both currencies are widely followed, the order flow can be thinner than in major pairs. That can translate into wider spreads and occasional spread jumps during quieter periods.
Exotics
**Exotic pairs** involve a major currency paired with a less frequently traded currency. These pairs can have wider spreads due to lower liquidity, fewer active counterparties, and potentially higher execution risk. For traders, this means the spread can be a more significant part of the total cost.
How trading sessions affect spreads (liquidity and time-of-day)
Spreads are not static. They often change throughout the trading day because liquidity changes as global trading centers open and close.
Higher-liquidity windows and overlaps
When major financial centers are active—and especially when sessions overlap—more participants tend to trade, which can improve liquidity and reduce spreads for many pairs. For traders in the UAE/GCC and Asia, it’s useful to think in terms of when the relevant currencies are most actively traded, rather than relying on a single “best time” rule.
Quieter hours and rollovers
During quieter market hours, fewer participants may be available to quote tight prices. Spreads can widen as a result. Some brokers also show noticeable spread changes around daily trading rollovers or during low-liquidity periods. This matters if you place orders at off-peak times, run automated strategies, or hold positions that might be stopped out by short-lived spread expansion.
Volatility and sudden spread widening
In fast markets, spreads can widen if liquidity providers pull back or update quotes more cautiously. Even without citing live prices, the principle is consistent: when uncertainty rises, the “cost of immediacy” tends to increase, and spreads may reflect that.
Spread types: fixed vs floating
Brokers may offer different spread structures:
Fixed spreads
**Fixed spreads** are designed to stay stable under normal conditions. This can make costs more predictable for beginners. However, fixed-spread accounts may embed a higher average cost to compensate for periods when market spreads would otherwise widen.
Floating (variable) spreads
**Floating spreads** change with market liquidity and volatility. They can be very low in liquid conditions, but they may widen during quiet periods or fast markets. For traders, the key is to evaluate not only the “minimum” spread promoted in marketing, but also typical behavior across different hours.
Broker pricing models: how commissions and spreads work together
Spreads should be evaluated alongside other charges, because brokers can structure costs in different ways:
Spread-only accounts
Some accounts charge primarily through the spread. The spread may be wider, but there may be no separate commission. This can be easier to understand, but you still need to compare the all-in cost.
Commission + raw/low spread accounts
Other accounts may offer lower spreads while adding a commission per trade. For active traders, comparing the **all-in trading cost** (spread plus commission) is usually more meaningful than looking at spreads alone.
Execution quality and slippage
Even if the displayed spread looks tight, the final cost can be affected by execution quality. In fast conditions, fills can occur at slightly different prices than requested (slippage). This is not inherently “good” or “bad,” but it’s part of real trading conditions and should be considered when evaluating a broker and a strategy.
How spreads translate into real trading costs (practical examples)
You don’t need live prices to understand the mechanics. Conceptually:
- · If the spread is wider, a position needs a larger favorable move to break even.
- · For frequent trading (scalping, intraday), spreads can accumulate into a meaningful cost.
- · For longer-term trading, spreads may matter less per trade, but they can still affect entries, exits, and stop-loss placement—especially during low-liquidity periods.
Why “typical” matters more than “from”
Broker websites often show minimum spreads (“from X”). Minimum values may occur only during the most liquid moments. For practical decision-making, focus on how spreads behave during the hours you actually trade and on the pairs you trade most.
Practical checks for traders comparing broker spreads
If you use a broker-review portal to shortlist brokers, spreads are one input—but they should be checked in a way that reflects real use. Here are practical, beginner-friendly checks:
1) Compare the same pair and the same account type
Spreads differ by instrument and account. Comparing Broker A’s EUR/USD on a commission account to Broker B’s GBP/JPY on a spread-only account isn’t meaningful. Keep the comparison consistent.
2) Ask: when are spreads measured?
If a broker publishes a “typical spread,” look for clarity on the trading hours and conditions it represents. If that information is not clear, treat headline spread claims cautiously.
3) Review total cost: spread + commission + swaps (if applicable)
The spread is not the only cost. If you trade a commission-based account, add commission to your assessment. If you hold positions overnight, understand that rollover or swap charges may also affect outcomes.
4) Watch for spread behavior during quiet hours
If you often trade during Asia hours, late US hours, or around daily rollovers, observe whether spreads widen materially in those windows. This can be especially important for tight-stop strategies.
5) Link pricing expectations to broker trust factors
Pricing is only one part of broker selection. When reading broker reviews, consider broader trust signals such as regulatory standing, complaint patterns, withdrawal reliability, and transparency in how reviews are handled. These factors can help you interpret whether the broker’s trading conditions and communications are likely to be consistent over time.
Common spread-related misunderstandings
“Lower spread always means cheaper trading”
Not necessarily. A low displayed spread can be paired with higher commissions, weaker execution, or wider spreads outside peak liquidity. Total cost and consistency matter.
“Spreads are the same 24/5”
Spreads commonly change with liquidity and volatility. This is a normal market characteristic, not automatically a sign of manipulation.
“If my stop-loss triggers, it must be a broker issue”
Stops can trigger due to real bid/ask pricing and temporary spread widening—especially during low liquidity. Understanding bid vs ask helps you place stops with more realistic buffers for the conditions you trade in.
Risk note for new traders
Forex trading involves risk, and transaction costs (including spreads, commissions, and potential slippage) can materially affect performance—particularly for frequent trading styles. Always ensure you understand a broker’s fee schedule and execution approach, and consider using a demo account to observe spread behavior across different sessions before trading with real funds.
