What exactly is the spread?
Every forex quote normally shows a bid price and an ask price. The ask is what a buyer pays; the bid is what a seller receives. Their difference is the bid–ask spread. On EUR/USD, for example, bid 1.08465 and ask 1.08477 differ by 0.00012, or 1.2 pips when one pip equals 0.0001.
That difference is a trading friction rather than a separate invoice. Assuming other conditions stay unchanged, buying at the ask and immediately closing at the bid means crossing the spread. During a longer trade, the eventual bid and ask can change with the market, so the realised outcome is not necessarily identical to a static example.
Minimum spread versus average spread
A minimum value describes a low point. It does not tell you how often that low point appeared, how long it lasted, or whether a typical order could be filled at it. A properly explained average represents observations sampled over time, but averages can also be misleading when brokers use different trading sessions, sample intervals or liquidity conditions.
The orange bar shows how a spread observed over many quotes can be higher than an advertised minimum. The example does not imply either number belongs to a specific broker.
To evaluate a statistic, ask what instrument and account it covers, whether the broker reports simple or time-weighted averages, what dates and hours were sampled, and whether the quoted spread excludes commission. A number without its methodology is difficult to compare responsibly.
Why spreads widen at different times
Liquidity and volatility influence quoted spreads. Overlapping, active sessions often have deeper liquidity, while the period around daily rollover, market reopenings or exceptional news can behave very differently. A broker may stream competitive quotes for most of the session and much wider quotes during brief episodes of stress.
The relevant benchmark therefore depends on how you trade. An intraday trader active during liquid hours should investigate spreads in those hours. A news trader needs to look at spreads when the release actually occurs, and an overnight trader must also account for financing and rollover conditions.
Turning pips into actual dollars
For an illustrative USD-denominated EUR/USD account, one standard 100,000-unit lot has a pip value of approximately $10. A 0.9-pip spread would then represent about $9 for a one-lot position, while a 0.2-lot position would have an estimated $1.80 spread cost. This example assumes a standard EUR/USD contract, typical pip definition and ignores slippage.
| Hypothetical quote | Spread | Cost at 1.0 lot | Cost at 0.2 lot |
|---|---|---|---|
| Minimum snapshot | 0.0 pip | $0 | $0 |
| Typical example | 0.9 pip | $9 | $1.80 |
| Widened example | 2.0 pips | $20 | $4 |
None of these figures includes commission. An account advertising a zero minimum spread but charging a $7 round-turn commission per lot can be more expensive than a spread-only account in some circumstances. For the full framework, read Forex Trading Costs Explained.
How to compare brokers without falling for the headline
Start with the same currency pair, trade size, holding period and expected trading session for every account. Record whether the figure is a minimum, average or indicative spread. Then add the account’s full opening-and-closing commission and applicable overnight charges before comparing totals.
Our True Trading Cost Calculator helps structure comparable trading scenarios, while Compare Broker Costs collects broker-by-broker research. Check each row’s pricing basis or verification status: an indicative or minimum-basis input should not be presented as measured average execution.
For context, see OANDA’s historical spread information and the UK FCA’s assessment of CFD price and value disclosures. Both reinforce why a single advertised spread cannot describe all trading costs.
The practical takeaway
“From 0.0 pips” is a starting point for questions, not an answer to what your trading will cost. A meaningful broker comparison needs transparent data definitions, a realistic trade profile and a calculation that includes the rest of the fee schedule.
Frequently Asked Questions
Does a 0.0-pip minimum mean trading is free?
No. That minimum may be brief and commissions, swaps or other charges may still apply. The actual fill can also differ from an indicative quote.
Is an average forex spread guaranteed?
No. An average is a summary of observations over a defined sample. Individual quotes can be lower or higher, particularly during volatile or illiquid conditions.
Should I compare minimum spreads across brokers?
Only as one data point. Compare published methodologies and typical spread data where available, then add commissions and financing on like-for-like trade sizes.
