The Biggest Mistake Traders Make

If I asked a room full of traders how they compare forex brokers, I already know what most of the answers would be.

“Low spreads.”

It’s one of the first things almost every trader looks for, and understandably so. Every trade begins with a cost. The lower that cost, the better… at least in theory.

That’s why broker websites are full of headlines like:

“Spreads from 0.0 pips.”

On the surface, comparing brokers seems straightforward. If one broker advertises spreads from 0.0 pips and another advertises spreads from 0.2 pips, the first one must be cheaper. Unfortunately, that’s where many comparisons stop.

After spending many years in the brokerage industry, I think this is one of the biggest mistakes traders make.

(Quick disclosure up front, since it’s relevant to everything that follows: I’m the founder and CEO of a brokerage called TabTrade. I’ll come back to why that matters later in this piece, including in the data, but I’d rather you know that now than find out at the end.)

Not because spreads don’t matter. They absolutely do. It’s because the number most traders compare often isn’t the number that determines what they’ll actually pay.

Imagine buying a car based solely on its advertised fuel consumption, only to discover those figures were achieved under perfect laboratory conditions that bear little resemblance to your daily commute. The advertised number wasn’t wrong, but it also wasn’t representative of your real-world experience.

Broker spreads work in a remarkably similar way. The figure that receives the biggest headline on a website is often the best spread the broker achieved under ideal market conditions. It tells you what was possible.

What it doesn’t necessarily tell you is what you’ll experience when you open an account, fund it, and start placing trades over the coming months or years. Those are two very different questions.

One asks:

What’s the lowest spread this broker has ever quoted?

The other asks:

What am I actually likely to pay every time I trade?

The distinction sounds subtle, but it can have a meaningful impact on your trading costs over time. In my opinion, understanding that difference is one of the simplest ways to become a better-informed trader, and once you recognise it, you’ll probably never compare brokers in quite the same way again.

What Is a Spread?

Before comparing minimum and average spreads, it’s worth taking a step back and understanding what a spread actually is.

Every tradeable financial instrument has two prices. The bid price is the price at which you can sell, and the ask price is the price at which you can buy. The difference between those two prices is known as the spread.

That difference exists because someone, usually a bank, a liquidity provider or a market maker, is standing ready to take the other side of your trade at any moment. The spread is effectively their compensation for providing that liquidity and absorbing the risk of holding a position until it can be offset elsewhere in the market.

For example, imagine EUR/USD is quoted like this:

  • Bid: 1.17500
  • Ask: 1.17510

The difference is one pip, so the spread is 1.0 pip.

If the market moves higher and the quote becomes:

  • Bid: 1.17500
  • Ask: 1.17502

the spread has narrowed to 0.2 pips.

If liquidity reduces, perhaps during major news events or quieter trading periods, the quote might become:

  • Bid: 1.17500
  • Ask: 1.17520

Now the spread has widened to 2.0 pips.

This is completely normal.

Contrary to what many newer traders assume, spreads are not fixed. They are constantly changing throughout the trading day as market conditions change.

When liquidity is high and buyers and sellers are actively trading, spreads generally become tighter; when liquidity falls, uncertainty increases, or markets become more volatile, they naturally widen.

That’s why there is no such thing as “the spread” for a currency pair. There are countless different spreads quoted throughout the day, every single trading day.

That simple fact is the foundation for everything that follows.

What Is a Minimum Spread?

Now that we know spreads are constantly changing, it’s easier to understand what a minimum spread actually represents: the lowest spread a broker observed on a particular instrument.

That’s it.

It isn’t a promise that every trader will receive that spread, or even that you’ll receive it most of the time. It’s simply the narrowest spread that occurred while the broker was measuring its prices.

For example, imagine a broker records the EUR/USD spread every second over an entire trading day.

Over those 86,400 observations, the spread might look something like this:

  • 0.0 pips for 45 seconds
  • 0.1 pips for 3 hours
  • 0.2 pips for 8 hours
  • 0.3 pips for 7 hours
  • Wider spreads during periods of lower liquidity

Even though the spread only reached 0.0 pips briefly, the broker can legitimately advertise:

Spreads from 0.0 pips.

That statement is factually correct.

In my experience, that 0.0 print usually isn’t even a fluke. It tends to happen for a fraction of a second, when a buy order and a sell order cross almost simultaneously. The liquidity provider on the other side isn’t really taking on any risk in that moment, so there’s nothing to charge for. It’s a genuine market condition, just not one that lasts.

There’s a common misconception here: that brokers are somehow being misleading when they advertise minimum spreads. In most cases, they’re not. If the spread genuinely reached that level, they’ve accurately described the lowest pricing that was available.

The difficulty is that many traders naturally interpret the statement differently.

When people see “from 0.0 pips”, they often assume that’s broadly representative of what they’ll experience when trading under normal market conditions.

In reality, the advertisement is describing the best-case scenario, not the typical one.

There’s nothing inherently wrong with publishing a minimum spread. The problem is using it as the primary way to compare two brokers.

By itself, it tells you very little about what your trading costs are actually likely to be over the lifetime of your account.

What Is an Average Spread?

If a minimum spread tells you the best pricing a broker achieved, an average spread attempts to answer a much more practical question.

What is a trader actually likely to pay?

Rather than focusing on a single point in time, an average spread looks at pricing over an extended period and calculates the average spread observed throughout that sample.

Instead of asking:

“How low did the spread get?”

it asks:

“What did the spread look like most of the time?”

That difference matters. Think about your own trading.

You don’t wait for the one moment each day when the spread hits its lowest point before placing every trade. You trade when your strategy tells you to trade. Sometimes that’s during the London session. Sometimes it’s during New York. Sometimes it’s immediately after an economic announcement, and sometimes it’s during quieter periods when liquidity isn’t quite as deep.

Over weeks, months and years, your trading experience isn’t defined by the single best spread a broker ever quoted. It’s defined by the thousands of spreads you actually traded through, which is exactly what an average spread is trying to capture.

Imagine two brokers.

Broker A

  • Minimum spread: 0.0 pips
  • Average spread: 0.7 pips

Broker B

  • Minimum spread: 0.2 pips
  • Average spread: 0.3 pips

If you only compared the advertised minimum spreads, Broker A would appear to be the cheaper option. If you compared the average spreads, you’d probably reach the opposite conclusion. This is why traders should be careful not to compare brokers using a single headline figure.

The question isn’t:

“Who has the lowest minimum spread?”

It’s:

“Who is likely to cost me less over the hundreds or thousands of trades I’ll place over the life of my account?”

That’s the question average spreads are designed to answer. Of course, that leads to another question: if average spreads provide a more realistic picture of trading costs, why don’t more brokers advertise them instead?

A Real-World Example

Imagine you’ve just accepted a new role that requires you to travel regularly between Sydney and Melbourne. You’ll be making the trip every few weeks for the foreseeable future, so choosing an airline isn’t just about your next flight. It’s about finding one you’ll probably use for years.

As you compare your options, one airline advertises fares from $99. Another doesn’t make the same headline claim, instead publishing data showing its average fare on the route is $140.

At first glance, the choice appears obvious. The first airline looks considerably cheaper.

Several months later, however, your experience tells a different story.

The advertised $99 fare genuinely exists, but only on a handful of flights at times you rarely travel. The flights you actually book are usually somewhere between $180 and $220. The second airline, meanwhile, consistently charges between $135 and $145 on the flights that suit your schedule.

The advertised fare wasn’t misleading. It simply represented the cheapest ticket the airline offered, not the price most regular travellers were likely to pay.

As your travel continues, you stop paying attention to the headline fare altogether. Instead, you begin asking a different question.

What am I actually going to pay over the next hundred flights?

That question is more useful because it reflects your real experience rather than the single best price that happened to exist.

Choosing a broker follows the same logic.

Opening a trading account isn’t a one-off transaction. It’s the start of an ongoing relationship. You’ll place trades during the London session, the New York session, around major economic announcements, and during quieter periods when liquidity naturally changes. Over the life of your account, your trading costs will be determined by the prices you actually trade through, not the tightest spread that briefly appeared under ideal market conditions.

That’s why the distinction between minimum and average spreads matters. A minimum spread tells you the best pricing a broker achieved; an average spread attempts to tell you the pricing you’re most likely to experience over time. For anyone comparing brokers with a long-term view, they’re answering two very different questions.

Why Brokers Advertise Minimum Spreads

If average spreads provide a more realistic picture of what traders are likely to pay, it’s reasonable to ask why minimum spreads have become the industry standard.

The answer isn’t that brokers are trying to hide anything. It’s that minimum spreads solve several practical problems.

For one thing, they’re simple.

Every trader understands what “spreads from 0.0 pips” means, even if they don’t fully appreciate how often that spread occurs. It’s a clear, concise marketing message that can be displayed on a website, in an advertisement, or on a broker comparison page without needing further explanation.

They’re also objective.

A broker either achieved that spread or it didn’t. There’s very little room for interpretation.

Average spreads, on the other hand, immediately raise questions:

  • Over what period were they measured?
  • Which trading sessions were included?
  • Were they measured every second, every minute, or every hour?
  • Were unusually volatile periods included?
  • Was the daily rollover included?
  • Which instruments were measured?

All of those decisions influence the final result, and without a clearly defined methodology, average spreads from two different brokers may not be directly comparable.

There’s also a commercial reality.

If you only have one number to capture a prospective client’s attention, every broker naturally wants that number to be as competitive as possible.

This isn’t unique to financial services.

Airlines advertise fares from a certain price.

Hotels advertise rooms from a certain nightly rate.

Car manufacturers advertise fuel consumption achieved under standardised testing conditions.

Internet providers advertise speeds up to a particular limit.

These advertisements aren’t necessarily misleading. They’re simply highlighting the most favourable figure that can legitimately be claimed.

The brokerage industry has evolved in much the same way.

Over time, minimum spreads became the common language used to compare pricing because they were easy to communicate, easy to verify, and easy for traders to understand.

The problem isn’t that minimum spreads exist. The problem is that many traders unknowingly use them as a proxy for their long-term trading costs.

They’re measuring the wrong thing.

I’ve sat in enough internal marketing reviews to know how this works in practice: someone pulls the tightest print from the last quarter’s tick data, checks it’s technically accurate, and it goes on the homepage. It’s rarely a deliberate attempt to mislead traders. It’s just how competitive marketing works when the metric that gets the most attention is also the easiest one to cherry-pick.

If your goal is to understand what you’ll actually pay across a full trading career, a minimum spread tells only a very small part of the story.

Why Measuring Average Spreads Is More Difficult Than It Sounds

By this point, it might seem obvious that every broker should simply publish its average spreads instead of its minimum spreads. In practice, it’s not nearly that straightforward.

Unlike a minimum spread, which is simply the single lowest spread observed, an average spread depends entirely on how it is measured. Two organisations can analyse the same broker and produce different average spreads while both being technically correct.

The first question is over what period should the data be collected?

A single trading day is unlikely to be representative. One week may include major economic announcements, while another may be relatively quiet. Market conditions change constantly, which is why a meaningful average generally requires a sufficiently large sample collected over an extended period.

The second question is how often should prices be sampled?

Foreign exchange prices update continuously, often many times per second. Measuring the spread every second may produce a different result from measuring it every minute or every five minutes. The more comprehensive the sampling, the more representative the final average is likely to be.

There’s a subtlety here that catches out a lot of comparison sites. Even second-by-second sampling can miss the sharpest spread spikes, because spreads can blow out and snap back within milliseconds during a major data release. A methodology built on those snapshots will systematically understate how wide spreads get during those moments. That’s true across every broker being measured, not just one.

Then there’s the question of when the market is being measured.

Should pricing during the daily rollover be included?

Every experienced trader knows that spreads naturally widen around rollover as liquidity temporarily falls between trading sessions. That’s the point in the day, typically around 5pm New York time, when major liquidity providers close their books for interest calculations. Trading desks hand over between the US close and the Asian session opening at around the same time, so for a few minutes, fewer participants are actively quoting and spreads widen almost everywhere at once. It isn’t specific to any one broker; it’s simply how the market behaves.

Some analysts argue those periods should be included because they are part of the trading day. Others argue they should be excluded because relatively little trading occurs during those few minutes and they can disproportionately influence the average.

Neither approach is inherently right or wrong. What matters is that the methodology is clearly explained and then applied consistently to every broker being compared.

There are other decisions to make as well.

Should the average be calculated across every instrument a broker offers, or only the most actively traded currency pairs? Should each currency pair carry the same weighting, or should EUR/USD contribute more heavily because it accounts for a much larger share of global trading volume?

Here’s something worth knowing: the gap between a broker’s best-case and average pricing is usually smallest on EUR/USD, the most liquid pair in the world, and widens considerably on minors and exotics. A broker’s “from 0.0 pips” headline is almost always built on EUR/USD. The same broker’s minimum-to-average gap on something like USD/ZAR or NZD/CHF can look very different, which matters if you trade anything outside the majors.

Each of those choices moves the number, which is exactly why average spreads deserve context.

An average spread without a published methodology is simply another number. It doesn’t say much about how that number was produced, or whether it’s comparable with the figures published by another broker.

That’s also why an independent set of eyes on the data matters so much. When every broker is assessed using the same methodology, traders can make much more meaningful comparisons than marketing claims alone would ever allow.

Why Independent Measurement Matters

One of the biggest challenges when comparing brokers is knowing which numbers you can trust.

Every broker has access to its own pricing data and, in many cases, there’s nothing stopping them from publishing average spreads calculated using their own methodology. Many do exactly that.

The difficulty for traders is that they have no easy way of knowing whether two brokers have measured those figures in the same way.

Imagine two brokers both claim an average EUR/USD spread of 0.2 pips. The numbers appear identical.

However, one broker may have measured pricing over an entire calendar month, while the other sampled just a few days. One may have included the daily rollover period, while the other excluded it. One may have sampled every price update throughout the day, while another only sampled periodically.

Each approach can produce a different result, but that doesn’t necessarily mean either broker is being dishonest. It simply means the figures aren’t directly comparable.

This is exactly why independent measurement carries so much weight.

Rather than asking every broker to report its own performance, an independent organisation applies a single methodology across every broker it measures. Every participant is assessed over the same period, using the same sampling approach and the same calculation method.

That creates something traders rarely get when comparing marketing material: a genuine like-for-like comparison.

One company doing exactly that is Datalyst, an independent pricing intelligence platform that samples pricing from over 10,000 real trading accounts to build its picture of spread volatility.

Rather than relying on figures supplied by brokers themselves, Datalyst independently measures pricing using a published methodology that is applied consistently across every broker in its comparison universe.

Whether you agree with every aspect of that methodology is almost beside the point. The important thing is that it is transparent, repeatable and independent.

As traders, we should always be cautious of numbers that can’t be independently verified. The same principle applies to execution speeds, slippage statistics, uptime claims and virtually every other performance metric published within the industry.

Independent data doesn’t eliminate debate, but it gives everyone a common starting point. In my view, that’s far more valuable than asking each broker to mark its own homework.

Independent doesn’t mean flawless, either. It’s still worth asking who funds the measurement, whether brokers pay to be included, and how the sample was assembled, because those things can shape coverage even when the methodology itself is sound. The same scrutiny this piece has applied to broker marketing should apply to any data source, Datalyst included.

What I Would Compare When Choosing a Broker

If I were opening a trading account today, minimum spreads wouldn’t be anywhere near the top of my checklist.

That might sound surprising given everything we’ve discussed, but even average spreads are only one part of the equation. They’re a far better indicator of likely trading costs than minimum spreads, but they’re still just one variable in a much bigger decision.

Over the years, I’ve come to believe there are a handful of questions every trader should ask before choosing a broker.

1. Are the trading costs independently verified?

This is the first thing I’d look for, for reasons already covered above. A self-reported number and an independently measured one are not the same thing, however close the figures look.

2. Who owns the business?

This is one of the most overlooked questions in the industry. Can you easily identify who owns the broker, find the directors or senior management, and verify that information independently? If something goes wrong, do you know who is ultimately responsible for the business you’re trusting with your money?

Transparency matters. Reputable financial institutions shouldn’t feel anonymous.

I’ve seen enough offshore, opaque brokerage structures over the years to know that ownership opacity is rarely accidental. It’s usually a choice.

3. Can I independently verify the broker’s regulatory status?

Don’t rely solely on what a website says.

If a broker claims to be licensed, take a few minutes to visit the regulator’s public register and verify it yourself. Confirm the company name, licence number and licence status.

Here’s where to look, depending on where the broker is based:

Most regulators worldwide maintain something similar, and it’s usually just a name and licence number search away.

It takes only a few minutes, yet surprisingly few traders ever do it.

4. What does execution quality actually look like?

Many brokers advertise “fast execution.”

That’s easy to say.

What’s much harder is demonstrating how that execution is measured, where orders are processed, what technology sits behind the trading infrastructure, and how consistently clients receive the prices they expect to receive.

Execution quality is difficult to summarise with a single number, but it’s an important part of the overall trading experience.

One practical test: ask whether the broker passes on positive slippage as readily as negative slippage. If price improvement only ever seems to run one way, that tells you more about execution quality than any marketing claim about speed.

5. How consistent are the trading conditions?

Consistency is often more valuable than occasional best-case performance.

I’d rather know that pricing remains competitive throughout the trading day than focus on the tightest spread achieved for a brief moment during ideal market conditions.

The same applies to platform stability, execution quality and customer support. A consistently good experience is usually worth far more than an exceptional experience that’s only delivered occasionally.

6. Is the broker transparent?

Finally, I’d look at the business as a whole: does it explain how it measures performance, publish meaningful data rather than marketing slogans, and can you independently verify the claims being made?

Transparency doesn’t guarantee quality, but it usually says a great deal about the culture of the business.

Choosing a broker shouldn’t come down to whichever company advertises the smallest number on its homepage.

It should come down to understanding the complete picture and making an informed decision based on information that can be independently verified.

Other Trading Costs People Often Ignore

By now, it should be clear that average spreads are generally a much more meaningful measure of trading costs than minimum spreads.

They’re just not the whole story.

A broker with the lowest average spreads won’t necessarily be the cheapest place to trade once every other cost is taken into account.

The most obvious example is commission.

Many professional-style accounts offer raw spreads with a fixed commission charged separately. That’s not inherently better or worse than an account with a wider spread and no commission. They’re simply different pricing models.

What matters is the all-in cost of completing a trade.

If Broker A averages a spread of 0.1 pips but charges a significantly higher commission than Broker B, the apparent pricing advantage may disappear altogether. Looking at spreads in isolation can therefore be just as misleading as looking only at minimum spreads.

Execution quality is another factor that deserves more attention than it gets.

Suppose two brokers both average 0.2 pips on EUR/USD.

On paper, they appear identical.

But if one consistently fills your orders at the requested price while the other regularly experiences delays, slippage or rejected orders during volatile market conditions, your actual trading costs may end up being materially different.

This becomes particularly important for shorter-term traders, where even small differences in execution quality accumulate fast across a high volume of trades.

Platform stability also matters.

The tightest spreads in the world are of little value if your trading platform freezes during major market events, disconnects unexpectedly, or struggles to process orders when volatility increases.

For traders who hold positions overnight, financing costs should also form part of the comparison.

Swap rates can vary considerably between brokers and, depending on your strategy, may have a much greater impact on profitability than small differences in spread.

Account fees are worth a mention too: inactivity charges, withdrawal fees, currency conversion charges on deposits. They’re smaller line items individually, but they compound over the life of an account in ways that rarely make it into any comparison table.

The broader point is this: trading costs should be viewed as a complete package rather than a single number.

Average spreads are an excellent starting point because they provide a far more realistic indication of day-to-day pricing than minimum spreads. But they should always be considered alongside commissions, execution quality, platform reliability, financing costs and the overall trading experience.

No single metric tells the whole story.

The most informed traders understand how each of these factors contributes to the true cost of trading and evaluate them together, rather than in isolation.

Datalyst says as much itself. Its own methodology notes state plainly that spreads don’t represent execution quality, slippage or any other broker fees. That’s a useful admission from an organisation with every incentive to present spread data as the complete picture, and it’s exactly the caveat this section has been making.

What the Independent Data Shows

Fortunately, traders no longer have to rely solely on marketing material when comparing pricing.

Independent pricing intelligence providers now monitor and analyse broker spreads using transparent methodologies over extended periods, allowing traders to compare pricing on a considerably more meaningful basis than headline advertising alone.

Datalyst, introduced earlier, is a useful illustration of what that looks like in practice. Its reports include both the methodology used and the underlying data, allowing traders to understand exactly how the figures were produced rather than simply accepting a marketing claim at face value.

Using Datalyst’s April 2026 analysis of the seven major currency pairs (EUR/USD, GBP/USD, USD/JPY, AUD/USD, NZD/USD, USD/CAD and USD/CHF) across 34 brokers, the table below shows the ten lowest average spreads recorded. It also includes a handful of additional widely recognised brokers for direct comparison, even though they didn’t place in the top ten:

Rank (of 34) Broker Account Type Average Spread
1 TabTrade Raw 0.04 pips
2 Deriv Raw 0.06 pips
3 Iron FX Razor 0.10 pips
4 Exness Raw Active 0.10 pips
5 Axi Raw Plus 0.12 pips
6 GO Markets Zero 0.14 pips
7 Tickmill DMA 0.14 pips
8 IC Markets Zero (ECN) 0.17 pips
9 BlackBull Zero Spread 0.18 pips
10 Pepperstone STP Zero 0.18 pips
12 CMC Markets Plus 0.23 pips
26 FXPro Premium 0.49 pips
30 XM Pro 0.74 pips
34 IG Standard 1.48 pips

Source: Datalyst, April 2026. Average spreads measured across seven major currency pairs, combined across trading sessions, daily rollover period excluded. Full results across all 34 measured brokers are available directly from Datalyst.

One caveat worth flagging: account names vary by broker, and pricing models differ accordingly. Some carry a separate commission on top of the spread shown; others build all costs into the spread itself. As covered earlier, that commission is part of the real cost of a trade, so it’s worth checking each broker’s own fee schedule rather than assuming average spread alone tells the whole story.

The same scrutiny applies here too: one month of data is a reasonable snapshot, but it’s exactly the kind of single-period sample this article has cautioned against treating as gospel. Spread rankings can shift from month to month, so treat this table as a strong indicator of where pricing sits today rather than a permanent scoreboard.

The rankings themselves are only part of the story. Two brokers, Deriv and Iron FX, came close enough to TabTrade’s result that the real story isn’t a runaway win. It’s that pricing at the sharp end of the market is genuinely competitive right now. That’s a more honest takeaway than a single headline number would suggest, and it’s the same principle this entire article has been making: look past the number that grabs attention and understand where it actually sits in context.

What I find more encouraging is the direction the industry is moving. Rather than asking traders to compare headline claims such as “spreads from 0.0 pips”, independent organisations are beginning to publish data that better reflects the pricing traders are likely to experience over time.

That’s good news for everyone.

It encourages greater transparency, allows more meaningful comparisons between brokers, and moves the debate away from marketing headlines and toward independently verifiable data.

As disclosed at the start of this piece, TabTrade was included in this comparison and recorded the lowest average spread during the reporting period. Whether you’re considering TabTrade or any other broker, my advice is exactly the same.

Whenever independent data is available, use it. It will almost always provide a clearer picture than comparing minimum spreads alone.

Final Thoughts

One of the things I enjoy most about the financial markets is that they’re built on data.

As traders, we spend our days analysing charts, testing ideas and making decisions based on evidence rather than assumptions. Yet when it comes to choosing a broker, many of us still rely on the biggest headline on a homepage.

I think we can do better than that.

Minimum spreads have their place. They’re a legitimate metric, and when presented accurately, there’s no issue with them. The mistake is assuming they tell the whole story.

Average spreads are one of the most useful indicators of what trading is actually likely to cost over time. They won’t tell you everything you need to know, but they provide a noticeably more representative picture than the single lowest spread a broker happened to quote under ideal market conditions.

More broadly, I hope the industry continues moving towards independently verified, transparent and comparable data.

Whether it’s spreads, execution quality, platform reliability or regulatory status, traders deserve information they can independently verify rather than simply accept at face value.

That’s ultimately why I wrote this article: not to tell you which broker to choose, but to encourage you to ask better questions before making that decision. If this article changes the way you compare brokers, then it’s achieved exactly what I hoped it would.

As I mentioned at the outset, I’m the founder and CEO of TabTrade, and naturally I’m biased in its favour. But I’d encourage you to apply exactly the same principles discussed in this article whether you’re evaluating TabTrade or any other broker.

Look beyond the headlines.

Understand how the numbers were measured.

Whenever possible, rely on independent data.

The more informed the industry becomes, the better this works for everyone.

Frequently Asked Questions

What’s the difference between a minimum spread and an average spread?

A minimum spread is the single lowest spread a broker has recorded on an instrument, usually for a brief moment under ideal market conditions. An average spread is calculated across a much larger sample over time, so it reflects the pricing a trader is actually likely to experience. Minimum spreads show what’s possible; average spreads show what’s typical.

Why do forex spreads change throughout the day?

Spreads widen and narrow constantly based on liquidity. They tend to be tightest when major trading sessions overlap and liquidity is deep, and they widen during quieter periods, around major news releases, and around the daily rollover when liquidity providers temporarily thin out their quoting.

Is a broker with the lowest average spread always the cheapest to trade with?

Not necessarily. Spread is only one part of the total cost of a trade. Commission, execution quality, swap rates, and account fees such as inactivity or withdrawal charges all affect the real cost of trading, and a broker with a slightly wider spread can still work out cheaper once those are accounted for.

How can I verify that a broker’s spread data is accurate?

Look for spread data measured by an independent third party using a published, consistent methodology, rather than figures a broker calculates and reports about itself. It’s also worth checking who funds the measurement and whether brokers pay to be included, since that can affect how trustworthy the comparison is.
