Tight and stable spreads: why they matter for every trader

In trading, profitability is often decided by details that look small on the surface, but compound dramatically over time. One of the most underestimated of these details is the spread, and understanding how it works can be the difference between consistent growth and slowly bleeding money on every position you open.

The spread is the difference between the bid price (where you sell) and the ask price (where you buy). In simple terms, it’s the cost you pay to enter a trade. If EUR/USD is quoted at a bid of 1.1300 and an ask of 1.1302, the spread is 2 pips. That means you start every trade slightly negative, and your position must move at least by the spread just to break even.

Why spreads directly affect your profitability

Spreads may look tiny, just a few pips, but they’re paid on every trade, on every position, regardless of whether you win or lose. The tighter the spread, the faster you reach break-even, the more of your move you keep as profit, and the easier it is to trade actively, whether you’re scalping, trading intraday, or positioning around events. This becomes especially critical once leverage is involved.

How spread impacts a real trade

Let’s take a realistic scenario and break it down. Imagine a trader with a $1,000 deposit trading Gold (XAU/USD) at a price of $5,400.00, where 1 lot equals 100 oz.

The spread cost formula is straightforward: Spread Cost (USD) = Spread (USD) x (Position Value / Gold Price).

With the same $1,000 deposit, different leverage levels create very different exposure. At 100:1 leverage, you control a $100,000 position using $1,000 in margin. At 200:1, that same deposit controls $200,000, and at 500:1 it controls $500,000.

Here’s where spreads start to matter. On a $100,000 position (roughly 18.52 oz), a $0.20 spread costs you $3.70, or 0.37% of your deposit. Widen that to $0.50 and it jumps to $9.26, nearly 1% gone before the trade even moves.

Scale up to a $200,000 position and the same $0.50 spread now costs $18.52, eating 1.85% of your deposit. At $500,000 exposure, a $0.50 spread costs $46.30, which is 4.63% of a $1,000 account, gone immediately.

The takeaway is clear: wider spreads scale linearly with position size. At higher exposure, they become a meaningful percentage of your deposit, and with tight stop-losses, this directly increases the chance of being stopped out before your trade has room to work.

Tight spreads are important, but stability is even more critical

Many traders focus only on average spread size, but experienced traders know the real danger lies elsewhere: spread widening during volatility.

During major economic releases like Consumer Price Index (CPI), Non-Farm Payrolls (NFP), or central bank rate decisions, some brokers dramatically widen their spreads. When that happens, stop-losses get triggered earlier than expected, profitable positions are closed prematurely, and risk management models break down. This is where many traders are stopped out, not because the trade idea was wrong, but because execution conditions deteriorated.

The chart below shows how PrimeXBT spreads compare with those of other major brokers during a volatile trading session on Thursday, 29 January 2026. As shown, we not only offer significantly lower spreads, but also maintain greater stability during market events. The green dots represent PrimeXBT spreads, while the other lines represent competing brokers, which are not named for ethical reasons.

Why stable spreads can decide success or failure

A stable spread means predictable execution, reliable stop-loss placement, and consistent risk-to-reward ratios. When spreads remain tight even during volatility, traders can hold positions through normal market noise, execute strategies with confidence, and avoid artificial losses caused by execution rather than price action. Over time, this consistency compounds into better results.

How to compare spreads between brokers

You can easily compare brokers by checking live spreads during different market sessions, observing how they behave during major news events, and comparing actual execution quality rather than just advertised “from” values.

This is where we stand out. At PrimeXBT, we offer consistently tight spreads, high spread stability during volatility, and transparent conditions that can be objectively compared. You don’t need marketing claims, just open charts side by side and watch how spreads behave when markets move.

Tight and stable spreads are part of a bigger mission

At PrimeXBT, tight and stable spreads aren’t a marketing feature. They’re part of a broader mission to empower traders with conditions and tools that help them achieve better results. Execution quality, predictable costs, and professional-grade trading conditions are foundational to long-term trading success.

Because in the end, your strategy matters, your discipline matters, your psychology matters, but execution conditions are what decide whether your edge survives reality.
