A long position in Forex is a trade that profits if a currency pair’s price rises; a short position profits if that price falls. Because every Forex trade buys one currency and sells the other at the same time, a long EUR/USD position is long euros and short US dollars. A short EUR/USD position is the reverse. This page uses a single pair, EUR/USD, to show how pips, spread, swap, and stop-loss distance turn a directional view into a profit or a loss. Figures below are illustrative and should be checked on a live ticket.

What a Long Position Is on EUR/USD
In a currency pair, the first code is the base and the second is the quote. EUR/USD is therefore “euros priced in US dollars.” Going long means buying the base and selling the quote: you buy euros and pay dollars. You profit if one euro becomes worth more dollars than you paid, after costs.
Suppose the broker quotes EUR/USD at 1.10000 bid / 1.10012 ask. A long is filled on the ask, so you buy at 1.10012, not at the mid or at the bid. If the ask later rises to 1.10512 and you close there, the pair has moved 50 pips in your favour on the ask side. Closing a long is selling, so you exit on the bid that exists at that later moment. The exact P/L depends on that bid, on position size, and on the spread at exit.
The position only cares about this pair’s price, not about either currency in isolation against a third currency.
What a Short Position Is on EUR/USD
Going short means selling the base and buying the quote: you sell euros and receive dollars. You profit if one euro becomes worth fewer dollars, so you can buy the euros back cheaper. A short is filled on the bid. Using the same quote of 1.10000 / 1.10012, a short sells at 1.10000.
To close a short you buy back, which uses the ask. If the market later shows 1.09500 / 1.09512, you buy at 1.09512. The move from 1.10000 to 1.09512 is 48.8 pips in your favour, even though the mid-market drop looks like a round 50 pips. That gap is the spread working against the exit, the same way it worked against the long on the way in.
Retail Forex trading lets you open a short as easily as a long. You are not borrowing physical banknotes. The broker books a CFD or a leveraged spot ticket. Losses on a short grow if the pair keeps rising and you have no stop, just as a long loses if the pair keeps falling.
Pips, Lots and a Worked P/L
Price on EUR/USD is usually quoted to five decimals. One pip is 0.0001 (the fourth decimal). A 1-pip move on a standard lot of 100,000 euros is about $10 when the account is in US dollars, because 100,000 × 0.0001 = $10. A mini lot (0.10) is about $1 per pip. A micro lot (0.01) is about $0.10 per pip. Those values are the usual teaching figures for EUR/USD; other pairs differ.
Long, 0.10 lot: buy 10,000 EUR at 1.10012. Notional ≈ $11,001. At 30:1 leverage, margin is about $367. Later you sell at 1.10500. Move = 0.00488 = 48.8 pips. Cash P/L ≈ 48.8 × $1 = $48.80 before swap and commission. On 1.00 lot that would be about $488.
Short, 0.10 lot: sell at 1.10000, buy back at 1.09512. Move = 48.8 pips; P/L ≈ $48.80. A 50-pip mid-market swing becomes 48.8 pips after a 1.2 pip spread. Direction does not cancel the spread.
| Ticket (illustrative EUR/USD) | Fill | Close | P/L on 0.10 lot |
|---|---|---|---|
| Long | Buy 1.10012 | Sell 1.10500 | +$48.80 |
| Short | Sell 1.10000 | Buy 1.09512 | +$48.80 |
| Long, stopped out | Buy 1.10012 | Sell 1.09612 | −$40.00 |
| Spread at open (1.2 pips) | Ask − bid | Immediate float | ≈ −$1.20 |

Spread Cost on Long and Short
The spread is paid when you cross it. A long starts at the ask and is marked to the bid; a short starts at the bid and is marked to the ask. Both open with a floating loss equal to the spread. On the 1.10000 / 1.10012 book, 1.2 pips × $1 on 0.10 lot is about $1.20. How wide that quote is depends in part on the type of Forex broker behind the ticket.
Spread is not a one-time curiosity. It widens around news and at rollover. If the spread jumps from 1.2 pips to 4.0 pips while you are long, the bid drops relative to the ask and equity falls even if the mid has not moved much. A short on the same book sees the ask jump away from the bid. Tight stops on either side can fill in that widening.
Commission accounts shrink the spread and add a per-lot fee. Either way, the pair must cover round-turn costs before the idea shows a profit.
Swap on an Overnight Position
If a long or a short is still open at the broker’s daily cut-off (often 21:00 or 22:00 server time, sometimes labelled 5 pm New York), a swap (rollover) is applied. Swap reflects the interest-rate differential between the two currencies, plus the broker’s markup. It can be a credit or a debit. Triple swap on Wednesday is common, to cover the weekend.
Illustrative numbers only: long EUR/USD swap −$6.50 per 1.00 lot per night; short EUR/USD +$2.10 per 1.00 lot per night. On 0.10 lot those figures become −$0.65 and +$0.21. Five nights on the long mini lot ≈ −$3.25, which is more than two pips. A swing trade that is “right” on direction can still lose if swap and spread eat the move. Live swap is printed in the symbol specification and can change without notice.
Islamic (swap-free) accounts may replace overnight interest with another admin fee. That fee is still a holding cost. Intraday trading styles that close before rollover avoid swap, but they pay the spread more often.
Stop Loss on a Long or a Short
A stop loss is an order that closes the position if price reaches a level you choose in advance. On a long EUR/USD, the stop sits below the entry (a sell stop). On a short, it sits above the entry (a buy stop). The stop does not change whether you are long or short; it only caps the design loss if it fills near the chosen price.
Continuing the mini-lot example: you risk $40, which is 40 pips × $1. On the long filled at 1.10012, a stop around 1.09612 is 40 pips. On a $4,000 account that $40 is 1% of equity. Position size should be derived from that risk, not from the largest lot the margin will allow. The method is covered in Forex risk management strategies.
Stops are not a guarantee of the exact price. A gap through 1.09612 after a data release can fill the sell stop at 1.09550, a worse loss. During extreme volatility the broker may reject a stop that sits inside the minimum stop level. Place the stop on the server (attached to the position), not only as a line on a chart, and size the lot so that a worse fill is still survivable.
Opening and Closing the Position
A position exists once the broker accepts the order and reports a fill. Until then you have an instruction, not exposure. Closing is the opposite ticket: sell to flatten a long, buy to flatten a short. Partial close reduces volume (for example 0.10 lot down to 0.05) and realises P/L on the closed slice only.
Hedging mode, common on MetaTrader, lets a long and a short on EUR/USD sit together as two tickets. Net exposure can be zero while both still pay spread and swap. Netting mode, more common on some MT5 and cTrader books, would collapse opposite orders into one net size. The trading platform shows which behaviour you are in; the contract specification confirms it.
Margin is reserved for the open volume. At 30:1, 0.10 lot EUR/USD near 1.10 uses roughly $367. If a second 0.10 lot is added in the same direction, used margin roughly doubles. If equity falls toward that used margin, the broker can liquidate.
Trading CFDs and Forex with leverage can result in losses that exceed the deposit. This page is educational and is not investment advice. Figures in the examples are illustrative and should be checked with the broker before they are used on a live order.
Frequently Asked Questions About Long and Short Positions
What is a long position in Forex?
A long position buys the base currency of the pair. On EUR/USD that means buying euros against US dollars. The trade profits if the pair’s price rises after costs.
What is a short position in Forex?
A short position sells the base currency. On EUR/USD that means selling euros against US dollars. The trade profits if the pair’s price falls after costs.
Do I buy at the ask and sell at the bid?
Yes. A long opens on the ask and closes on the bid. A short opens on the bid and closes on the ask. That is why both directions pay the spread.
How do I calculate profit on a long EUR/USD trade?
Subtract the entry ask from the exit bid (in price terms), convert the difference to pips, and multiply by pip value for your lot size. Then subtract commission and swap if they apply.
Does swap apply to both long and short positions?
Yes, if the position is held through the broker’s daily rollover. One direction may be charged and the other credited. The amounts are not symmetric and can change.
Where should a stop loss sit on a long or a short?
Below entry on a long, above entry on a short, at a distance that matches the cash you are prepared to lose given the lot size. Stops can fill at a worse price in a gap.
Can I hold a long and a short on EUR/USD at the same time?
On hedging accounts, yes: two separate tickets. On netting accounts, an opposite order reduces or closes the existing position instead of opening a second one.
Is a short position riskier than a long?
Both can lose more than the margin posted if price runs against the ticket and leverage is high. A short can keep losing as the pair rises; a long can keep losing as the pair falls. A stop and a smaller lot reduce that exposure; they do not remove it.
Summary
On EUR/USD, long means buy the euro against the dollar and profit from a higher pair price. Short means sell the euro against the dollar and profit from a lower pair price. Both start by paying the spread. Both can pay or receive swap if held through rollover. Pip value scales with lot size: about $10, $1, or $0.10 per pip on standard, mini, and micro lots in a USD account.
