Understanding what is spread in forex trading is one of the most fundamental skills for any trader. The spread represents a real, ongoing cost that directly affects your profitability on every single trade you take, whether you win or lose. This guide explains the different types of spreads, what causes them to change, and practical strategies to minimize their impact on your trading account.

What is a Spread?
In forex trading, the spread is the difference between the bid price (the price at which you can sell a currency pair) and the ask price (the price at which you can buy it). If EUR/USD is quoted at 1.08500 bid and 1.08515 ask, the spread is 1.5 pips. This means the moment you open a buy position, you are already 1.5 pips in the red because you bought at the higher ask price and would need the price to rise by at least 1.5 pips just to break even.
The spread serves as the primary way that market makers and dealing desk brokers earn revenue. Instead of charging you a direct commission, they profit from buying slightly lower and selling slightly higher than the current market price. This cost is invisible on your platform in the sense that you never see a separate bill for it, but it is very real and compounds over hundreds or thousands of trades.
Understanding the spread is crucial because it affects your breakeven point, your effective risk per trade, and the viability of short-term trading strategies. A scalper aiming for 3 pips profit per trade faces a much harder challenge with a 2 pip spread than a swing trader targeting 100 pips with the same spread.

Types of Spreads
Fixed Spreads
With a fixed spread, the broker guarantees that the spread will not change regardless of market conditions. For example, EUR/USD might always be offered at 1.5 pips, whether the market is calm or volatile. The advantage is predictability: you always know your entry cost in advance, which makes risk calculation simpler. This can be particularly useful for beginners who are still learning how costs affect their trades.
However, fixed spreads come with significant drawbacks. During major news events or periods of low liquidity, the broker may temporarily widen the spread (called a "spread widen" clause hidden in the terms), meaning your supposedly fixed spread is not always truly fixed. Fixed spreads also tend to be wider on average than variable spreads during normal market conditions, meaning you may pay more over time if you primarily trade during stable periods.
Variable Spreads
Variable spreads fluctuate based on market conditions, liquidity and volatility. During calm, liquid market conditions, variable spreads can be extremely tight, sometimes as low as 0.0 to 0.2 pips on EUR/USD through ECN (Electronic Communication Network) pricing. This makes variable spreads the preferred choice for day traders and scalpers who need the lowest possible costs during normal trading hours.
The downside is that variable spreads can widen dramatically during volatile events. A spread that is normally 0.5 pips might jump to 5, 10 or even 50 pips during a major news release like the US Non-Farm Payrolls report. This means your stop loss might be triggered not because the market moved against your trade, but because the spread itself consumed your stop distance. Traders using variable spreads must account for spread widening in their risk management calculations.
What Causes Spreads to Widen?
Several factors influence spread width throughout the trading day. Understanding these factors helps you plan your trading around the most cost-effective times.
Market liquidity is the primary driver. The forex market has peak liquidity during the London-New York session overlap (roughly 1:00 PM to 6:00 PM UTC), when both European and American banks are active simultaneously. During this overlap, spreads on major pairs are typically at their tightest. Conversely, during the low-liquidity period between the New York close and the Tokyo open (roughly 9:00 PM to midnight UTC), spreads tend to widen significantly.
News events cause sudden spread widening as market makers adjust their risk exposure. When economic data is released, prices can gap and move rapidly in either direction. Brokers protect themselves by widening spreads, sometimes by 10 to 50 times their normal level. Major events to watch include central bank interest rate decisions, GDP releases, employment reports (especially US NFP), and geopolitical developments.
Market sentiment and volatility also play a role. During periods of market panic or uncertainty, such as the onset of the COVID-19 pandemic or major geopolitical conflicts, spreads across all pairs can widen and remain elevated for extended periods. Even normally liquid pairs like EUR/USD can see spreads 3 to 5 times their normal level during these events.
How Spread Affects Your Trading
The impact of spread depends heavily on your trading style and timeframe. For scalpers who aim to capture just a few pips per trade, the spread represents a significant percentage of each trade's target. If your strategy targets 5 pips profit but the spread is 1.5 pips, the spread consumes 30% of your potential gain. This makes profitability much harder to achieve and means the strategy needs a substantially higher win rate to be profitable.
For swing traders and position traders who hold positions for days or weeks and target 50 to 200 pips or more, the spread is relatively minor. A 1.5 pip spread on a 150-pip trade is just 1% of the total move. This is one reason why longer-term trading styles tend to have higher success rates among retail traders compared to scalping or high-frequency day trading.
Spread also affects your effective risk per trade. If you set a stop loss at 20 pips and the spread is 1.5 pips, your actual risk is 21.5 pips because you are already 1.5 pips behind at entry. This should be factored into your position sizing calculations. Our Risk Calculator and Lot Size Calculator can help you account for spread costs when calculating your position size.
Tips for Minimizing Spread Costs
While you cannot eliminate spreads entirely, several strategies can help reduce their impact on your trading. First, prefer trading the major currency pairs (EUR/USD, GBP/USD, USD/JPY, USD/CHF) which have the tightest spreads due to their high liquidity. Exotic pairs like USD/TRY or EUR/ZAR can have spreads 10 to 30 times wider than majors.
Second, trade during high-liquidity sessions, particularly the London-New York overlap. The tighter spreads during this window can save you significant money over hundreds of trades compared to trading during the Asian session or the low-liquidity period between sessions. Third, compare brokers regularly, as spreads can differ substantially between providers, and consider whether an ECN account with commission pricing would be cheaper for your specific trading volume.
