Understanding Bid and Ask

Why Forex Has Two Prices

A forex quote is not a single price you can use for every transaction. It has two sides: the bid and the ask. Understanding which side applies helps explain your entry price, your exit price, and why a newly opened trade can immediately show a small unrealized loss.

The key rule is simple: you buy at the ask and sell at the bid. That rule applies whether you are opening a position or closing one. Once you connect each action to its matching price, the quote becomes much easier to read.

What Are the Bid and Ask?

The bid is the quoted price at which you can sell the base currency. The ask is the quoted price at which you can buy it. The base currency is the first currency in a pair; the second is the quote currency.

For EUR/USD, the euro is the base currency and the US dollar is the quote currency. A price of 1.1000 means one euro is valued at 1.1000 US dollars. Buying EUR/USD means buying euros against dollars; selling EUR/USD means selling euros against dollars.

Consider this entirely hypothetical quote, used only to explain the mechanics:

• EUR/USD bid: 1.1000
• EUR/USD ask: 1.1002

At those quoted prices, a buy would use 1.1002 and a sell would use 1.1000. These are schematic examples, not live market data or trade recommendations. Actual execution can differ from the displayed quote if prices move or available liquidity changes.

The Spread Is the Gap Between Them

The difference between the ask and the bid is called the spread. In our example, subtracting 1.1000 from 1.1002 gives 0.0002. For EUR/USD, one standard pip is 0.0001, so this quote has a spread of two pips.

Some platforms display EUR/USD to five decimal places. That extra digit represents a fractional pip, often called a point or pipette depending on the platform. A quote of 1.10000 / 1.10020 still has a two-pip spread, not a twenty-pip spread.

The spread is a trading cost embedded in the difference between the available buying and selling prices. It is not necessarily the only cost. Depending on the account and instrument, commission and overnight financing charges may also apply.

Following a Buy From Entry to Exit

Suppose you open a buy position at the hypothetical ask of 1.1002. To close that position, you must sell, so the relevant exit price is the bid.

If the quote remains 1.1000 / 1.1002 and you close immediately, you sell at 1.1000. The difference between entry and exit is a two-pip loss before any separate charges. This explains why an open position commonly begins with negative unrealized profit and loss: its available exit price is on the other side of the spread.

Now imagine the quote changes to 1.1002 / 1.1004. You could close the buy at the new bid of 1.1002, matching your entry price. That is price-only break-even, not necessarily account break-even. Any applicable commission, financing, or execution difference still needs to be included.

Following a Sell From Entry to Exit

The same logic works in reverse for a sell position. Suppose you sell EUR/USD at the hypothetical bid of 1.1000. Closing that position requires buying it back, so your exit uses the ask.

If the quote remains 1.1000 / 1.1002, an immediate close means buying back at 1.1002. Again, the price difference represents a two-pip loss before separate charges.

If the quote later becomes 1.0998 / 1.1000, the ask now matches your original selling price. Buying back at 1.1000 would produce price-only break-even. Notice that the relevant price for closing a sell is always the ask, not the bid that may be most visible on your chart.

Why the Chart Can Look Different

Many retail forex charts display bid prices by default, although chart settings and data sources vary. A visible chart level may therefore show only one side of the quote. The ask can sit above that level by the current spread.

This matters when reviewing entries, exits, and protective orders. A short position closes through a buy transaction, making the ask important. However, the exact trigger rules for stop and limit orders depend on the broker, platform, and product. Check those rules rather than assuming every order is triggered by the displayed chart price.

A Simple Quote-Reading Checklist

• Identify the action: Are you buying or selling, including when you close?
• Choose the matching side: Buying uses the ask; selling uses the bid.
• Measure the spread: Subtract the bid from the ask and convert using the pair's pip convention.
• Check other costs: Do not treat price-only break-even as the final net result.

Spreads can widen when liquidity is thinner or uncertainty increases. Before placing an order, look at the current quote rather than assuming the spread is constant. Bid and ask knowledge does not remove trading risk, but it helps you understand the actual prices involved in entering and leaving a position.
