Going Long vs Going Short in Forex: Buy and Sell Explained

What does going long and going short mean in forex?

Going long means buying a currency pair because you expect its price to rise. Going short means selling the pair because you expect its price to fall. Either way you close the trade later with the opposite action, and your profit or loss is the difference between the two prices multiplied by your trade size.

On a trading platform, long and short are simply the Buy and Sell buttons. The words say nothing about time: a long trade can last two minutes and a short trade can last two months.

Why every forex trade is long one currency and short the other

A currency has no price on its own. It is always priced against another currency, which is why forex is quoted in pairs (see how currency pairs are built). In EUR/USD, the euro is the base currency, the first one, and the US dollar is the quote currency. The price tells you how many dollars one euro costs.

So when you buy EUR/USD you do two things at once: you buy euros and you sell dollars. You are long the euro and short the dollar. When you sell EUR/USD you are short the euro and long the dollar.

This matters most on pairs where the dollar comes first. Buying USD/JPY means buying dollars and selling yen. If you think the yen will get stronger, you sell USD/JPY. Many beginners get this backwards.

How do you profit when the price falls?

Think of a short as the same trade in reverse order. In a long, you buy first and sell later at a higher price. In a short, you sell first and buy back later at a lower price. The gain still comes from selling high and buying low; only the order has changed.

In currency terms it is even simpler. When EUR/USD falls, the dollar is rising against the euro, so a short on EUR/USD is simply a trade in favour of the dollar. A falling chart is not bad news in forex.

Bid and ask: which price do you get?

Your platform shows two prices for every pair. The bid is the price you can sell at. The ask is the price you can buy at, and it is always a little higher. The gap between them is the spread, the built-in cost of every trade, explained in spreads and pips.

• Open a long: you buy at the ask. You later close it by selling at the bid.
• Open a short: you sell at the bid. You later close it by buying at the ask.

Both directions cross the spread exactly once, so both cost the same. It is also why every new trade shows a small loss the moment it opens: if you closed it straight away, you would get the other, worse price.

Worked example: going long on EUR/USD

Suppose EUR/USD is quoted at 1.1000 bid and 1.1001 ask, a spread of 1 pip (a pip is the smallest standard price step, 0.0001 on this pair). You buy 0.10 lots, which is 10,000 euros. At that size each pip is worth about $1.

• You enter: buy at the ask, 1.1001.
• Price rises: the quote becomes 1.1050 bid and 1.1051 ask. You close by selling at the bid, 1.1050.
• Result: 1.1050 − 1.1001 = 0.0049, which is 49 pips. 49 × $1 = $49 profit.
• If price had fallen instead: you close at a bid of 1.0960. 1.0960 − 1.1001 = −0.0041, which is 41 pips. 41 × $1 = $41 loss.

In the winning case the market moved 50 pips and you kept 49. The missing pip is the spread. Check sums like these in the profit calculator.

Worked example: going short on EUR/USD

Start from the same hypothetical quote, 1.1000 bid and 1.1001 ask, and the same 0.10 lots.

• You enter: sell at the bid, 1.1000.
• Price falls: the quote becomes 1.0950 bid and 1.0951 ask. You close by buying at the ask, 1.0951.
• Result: 1.1000 − 1.0951 = 0.0049, which is 49 pips. 49 × $1 = $49 profit.
• If price had risen instead: you close at an ask of 1.1041. 1.1000 − 1.1041 = −0.0041, which is 41 pips. 41 × $1 = $41 loss.

Everything is a mirror image, including your protective orders. On a short, the stop-loss (the order that closes a losing trade for you) sits above your entry and the take-profit sits below it. Our guide to stop-loss placement covers where to put them.

What does closing a position mean?

A position is an open trade. While it is open, the profit or loss on your screen is only a running figure that changes with every price tick. Closing means making the opposite trade of the same size: you sell what you bought, or buy back what you sold. Only then does the result become final and move into your account balance.

You can close by hand, or let an order do it: a stop-loss, a take-profit or, in the worst case, the broker’s automatic stop-out when your margin runs too low. You can also close part of a trade, such as 0.05 of a 0.10-lot position. See lot sizes and order types for the order types.

One trap: on many MetaTrader accounts, pressing Sell while you hold a Buy does not close it. It opens a second, opposite position, and you pay the spread again. To close, use the close button on the trade itself.

Short selling forex vs shorting shares

With shares, going short is a special process. Your broker must find shares to borrow, you sell them, and later you buy them back and return them. There can be borrowing fees, limits on which shares you may short, and sometimes outright bans.

Retail forex has no borrowing step. You are not dealing in physical money; you hold a contract with your broker, usually a contract for difference (CFD), that pays the change in price between entry and exit. A contract that gains when the price falls is as easy to create as one that gains when it rises, so the Sell button needs the same margin (the deposit set aside for the trade) as the Buy button.

There is a deeper reason too. Every currency deal is already a sale of one currency for another, so selling is normal, not special. We compare the two markets in forex vs stocks.

Does swap differ for long and short trades?

Yes. Swap is a small overnight fee or credit on trades left open past the daily cut-off at 5pm New York time. It comes from the interest-rate gap between the two currencies, so the long and short sides of the same pair have different rates. One side may earn a little while the other pays, and after the broker’s markup both often pay.

If you close your trades before that cut-off, swap never touches you. If you hold for days or weeks, check the rate for your direction first. Forex swap fees explained shows where to find it, and since rates vary from firm to firm, they are worth a look when you compare regulated brokers.

Common beginner confusions about buy and sell

• “I need to own euros before I can sell them.” You do not. A short is a contract on the price, and it needs only margin in your account.
• “My stop was hit but the chart never touched it.” Most platforms draw the chart from the bid price. A short closes at the ask, which sits one spread higher, so a stop on a short can trigger just before the chart line appears to reach it.
• “Buying and selling the same pair at once is safe.” Holding both directions just freezes your result while you pay two spreads.

The best cure for all of these is practice with no money at stake. Place a few long and short trades on a forex demo account and watch how the profit figure moves in each case.

Being able to trade in both directions doubles your choices, not your chances: a short loses money as quickly as a long when the market goes the other way. Forex and CFDs are leveraged products with a high risk of loss. Only trade with money you can afford to lose.
