Bid and Ask Price in Forex: How Currency Quotes Really Work

When a forex trader looks at a currency pair, there is never just one price. The platform normally displays two prices side by side: the bid and the ask.

At first, the difference may seem insignificant. On a liquid pair, the two numbers may be separated by only a fraction of a pip. Yet those two prices determine where a buy trade actually opens, where a sell trade opens, how positions are closed, and why a newly opened trade often begins with a small unrealised loss.

Understanding bid and ask prices makes many other forex concepts easier to understand, including spread, stop-loss execution, take-profit levels, chart pricing, and transaction costs.

What is the bid price in forex?

The bid price is the price at which the market is currently willing to buy the base currency from the trader.

From the trader's point of view, it is normally the price used when selling.

Suppose EUR/USD is quoted as:

1.1048 / 1.1050

The first number, 1.1048, is the bid price.

If a trader sends a market sell order, the position would normally be opened around the bid price available at that moment, subject to execution conditions and possible slippage.

The same bid price is also relevant when an existing buy position is closed, because closing a long position requires selling the currency pair back into the market.

What is the ask price?

The ask price, sometimes called the offer price, is the price at which the market is willing to sell the base currency to the trader.

From the trader's point of view, it is normally the price used when buying.

Using the same quote:

1.1048 / 1.1050

The ask price is 1.1050.

A trader entering a market buy order would normally buy around this price. If the trader already has a sell position and wants to close it, the position must be bought back, so the ask price becomes relevant.

This distinction is simple once understood, but it explains a large part of how forex execution works.

Why does forex show two prices?

A currency pair shows two prices because buyers and sellers are not usually willing to transact at exactly the same level.

Buyers want to pay slightly less. Sellers want to receive slightly more.

The best available buying price becomes the bid. The best available selling price becomes the ask.

The difference between the two is the spread.

If EUR/USD is quoted at 1.1048 bid and 1.1050 ask, the spread is 0.0002, or 2 pips under a standard four-decimal quotation.

In modern platforms that show fractional pips, the displayed quote may contain five decimal places, but the same principle applies.

Why a buy trade opens at the ask price

A common source of confusion for new traders is seeing a buy order open slightly above the price line they were watching.

This happens because many charts primarily display the bid price, while a buy order is executed using the ask price.

Suppose the chart shows EUR/USD around 1.1048 and the spread is 2 pips. The corresponding ask price may be 1.1050. When the trader clicks Buy, the position opens around 1.1050 rather than 1.1048.

Nothing unusual has happened. The chart and the order are simply referring to different sides of the quote.

This becomes especially noticeable when spreads widen.

Why a sell trade opens at the bid price

A market sell order normally opens at the bid price.

If EUR/USD is quoted at:

Bid: 1.1048
Ask: 1.1050

A new short position would normally be opened around 1.1048.

To close that short position later, the trader must buy EUR/USD back, which means the ask price will be used.

For a short trade to become profitable, the ask price therefore needs to move below the original selling price by enough to cover the spread and any other trading costs.

Why trades often start in negative territory

A newly opened forex trade often shows a small unrealised loss immediately.

This is mainly because the trade enters on one side of the bid-ask spread but would need to exit on the other side.

For a buy trade, the trader enters at the ask price. If the position were closed immediately, it would be sold at the lower bid price.

For a sell trade, the trader enters at the bid price. Closing immediately would require buying back at the higher ask price.

The initial difference is the spread cost.

This is why price must move slightly in the trader's favour before the position reaches breakeven.

How bid and ask affect long positions

A long position profits when the market rises enough for the bid price to exceed the original ask entry price.

Suppose EUR/USD is:

1.1000 bid / 1.1002 ask

A trader buys at approximately 1.1002.

Later, the quote becomes:

1.1010 bid / 1.1012 ask

If the trader closes the position, it is sold at approximately 1.1010. The gross price difference between the entry at 1.1002 and exit at 1.1010 is 8 pips.

The important detail is that the trader did not buy and sell using the same side of the quote.

How bid and ask affect short positions

A short position works in the opposite direction.

Suppose EUR/USD is:

1.1000 bid / 1.1002 ask

The trader sells at approximately 1.1000.

Later, the pair falls to:

1.0990 bid / 1.0992 ask

To close the short position, the trader buys back at approximately 1.0992.

The gross difference between 1.1000 and 1.0992 is 8 pips.

Again, both sides of the quote matter when calculating the real result.

Bid and ask prices around stop loss

Bid and ask prices can also explain why a stop loss occasionally appears to trigger when the visible chart seems not to have touched the level.

For a buy position, the stop loss is triggered when the relevant selling price reaches the stop level. Since a long position is closed by selling, the bid price matters.

For a sell position, closing requires buying, so the ask price matters.

If a chart displays only bid prices, a sell-position stop loss can sometimes be triggered even though the visible bid candle appears to remain below the stop. The ask price may have reached it because of the spread.

This becomes more noticeable during periods of wider spreads.

Bid and ask prices around take profit

The same principle applies to take-profit orders.

A long position needs to be sold to close, so the bid price must reach the relevant take-profit level.

A short position must be bought back, so the ask price needs to reach the take-profit level.

This is important when targets are placed very close to current price. A trader may see the chart almost touch a target but find that the position remains open because the correct side of the quote has not yet reached the required level.

The difference may be tiny in normal conditions, but it can become more noticeable when spreads expand.

Why spreads between bid and ask change

The distance between bid and ask is not always constant.

During highly liquid periods, competition among buyers, sellers, banks, and liquidity providers can keep the two prices close together. This produces a tighter spread.

When liquidity weakens or uncertainty rises, the best available buyer may step further down while the best seller asks for a higher price. The spread then becomes wider.

This often happens around:

• Major economic announcements

• Daily rollover

• Market holidays

• Sudden geopolitical events

• Illiquid trading periods

• Sharp volatility

A wider spread affects both entries and exits because the two sides of the quote are further apart.

Bid and ask on major and exotic currency pairs

Major currency pairs usually have smaller bid-ask differences under normal conditions because they attract large amounts of trading activity.

Pairs such as EUR/USD and USD/JPY generally benefit from deep liquidity.

Less actively traded currency pairs may show wider spreads because fewer buyers and sellers are competing around each price level.

Exotic currency pairs can have substantially wider spreads, particularly during quieter hours.

A trader comparing two setups should therefore look beyond the chart pattern itself. The bid-ask structure can materially change the cost of entering and exiting.

Why chart price can differ between brokers

Forex does not operate through one centralised exchange providing a single universal retail quote.

Different brokers may receive pricing from different banks, liquidity providers, or aggregated sources. As a result, small differences can appear between platforms.

One broker may show a slightly different bid or ask price from another at the same moment. The difference is usually small in highly liquid major pairs, but it can become more visible during fast markets or thin liquidity.

This is also why candles can occasionally look slightly different across two trading platforms.

A small quotation difference does not necessarily mean one price is incorrect. It may reflect a different pricing source.

Bid, ask and five-digit pricing

Many modern forex platforms quote major pairs using five decimal places instead of four.

For example:

EUR/USD 1.10483 / 1.10495

The fifth decimal place represents a fractional pip, often called a pipette.

In this example, the difference between the prices is 0.00012, which equals 1.2 pips.

Japanese yen pairs often use three decimal places under fractional pricing because a conventional pip is measured at the second decimal place.

Understanding fractional pricing prevents traders from confusing points, pipettes, and full pips when reading a platform.

Bid and ask in pending orders

Pending orders also depend on the correct side of the quote.

A buy order eventually needs an ask price at which the market can sell to the trader. A sell order relies on the bid price at which the market can buy from the trader.

This matters particularly when placing orders close to current market price.

A trader may see the visible chart touch a planned entry zone while the pending order remains inactive because the side of the quote required to trigger that order has not reached the level.

The exact behaviour also depends on the platform and order type, so traders should understand how their trading software handles triggers.

Why very tight strategies are more sensitive to bid and ask

The smaller the target, the more important the bid-ask difference becomes.

If a trader is targeting 100 pips, a 1-pip spread represents a relatively small part of the expected move.

If a scalper targets only 4 or 5 pips, the same spread represents a much larger proportion of the potential reward.

This is why short-term strategies need to pay close attention to:

• Current spread

• Session liquidity

• Execution speed

• Slippage

• Commission

• Bid and ask behaviour

A strategy can look profitable on a clean chart while becoming much less attractive once the real entry and exit prices are considered.

Common mistakes when reading bid and ask prices

One common mistake is assuming the chart price is the exact price used for every transaction.

Another is forgetting that a buy opens at the ask but closes at the bid, while a sell opens at the bid and closes at the ask.

Some traders also misunderstand why a sell-position stop loss can trigger before the visible chart reaches it. The missing detail is often the ask price.

Another mistake is comparing spreads from different brokers without checking whether the platform displays fractional pips or full pips.

Finally, some traders look only at the displayed spread under calm conditions. The relevant question is how the bid and ask behave during the actual periods when the strategy trades.

How traders can use bid and ask information in practice

Traders do not need to watch both prices continuously for every trade. They do need to understand which side controls each type of execution.

Before entering, check whether the spread is normal for the pair and session.

When using very tight stop losses or pending orders, consider displaying both bid and ask lines if the platform supports it.

When reviewing a trade that appears to have triggered unexpectedly, check the spread and the correct side of the quote before assuming that the platform executed incorrectly.

For short-term strategies, record the actual entry and exit prices rather than judging performance only from chart candles.

These habits produce a more realistic understanding of trading costs and execution.

Final thoughts

Bid and ask prices are the two sides of every forex quote.

The bid is generally the price available when the trader sells, while the ask is the price available when the trader buys. The difference between them forms the spread.

Understanding these two prices explains why trades begin slightly negative, why buy and sell positions close at different sides of the quote, and why stop-loss or pending-order behaviour can sometimes look different from the visible chart.

Bid and ask prices may appear to be a small technical detail, but they are part of every forex transaction. Knowing how they work makes order execution much easier to understand.
