Going long: you think the price will rise
When you go long, you are telling the exchange: I want to profit if this coin gets more expensive. Say bitcoin is at 60,000 and you open a long worth 500 USDT — that is the size of the trade, not the money you need sitting in your account, because the exchange only sets part of it aside as your deposit (illustrative numbers). If the price climbs 2% to 61,200, your trade is up about 10 USDT. If it slips 2% the other way, you are down about the same, minus the small fee the exchange charges when you open and when you close.
That deposit the exchange holds while your trade is open is called margin, and on a 500 USDT position it can be a fraction of that amount depending on your leverage — that is the setting that lets you open a bigger trade with the same money, see what leverage is and what margin is. The word "long" itself comes from old market slang and says nothing about time: a long position is not a "long-term" trade. You can hold it for ten minutes or ten days. "Long" only tells you which direction pays you.
Going short: you think the price will fall
A short is the mirror image. Same 500 USDT position on bitcoin at 60,000, but this time you profit if the price drops. Bitcoin falls 2% to 58,800 and you are up about 10 USDT; it rises 2% instead and you are down about 10 USDT. Nothing exotic is happening — you simply picked the other side of the same market.
This is the thing that surprises most newcomers: on futures, a falling market is not automatically bad news. It is just another direction to trade. We go deeper into that idea on the page about making money when the price is falling.
Where does the profit actually come from?
A futures contract is an agreement about price, not a purchase of coins. When you open a long, someone else on the exchange is holding the opposite side — a short — on the same contract. The price moves, and money flows from one side to the other: the exchange calculates the difference between your entry price and your exit price and credits or debits your account in USDT.
That is why you never touch the coin itself. You do not borrow bitcoin, you do not receive bitcoin, and you do not need to own any to short it. If that sounds strange, the page on trading bitcoin without owning it walks through it, and what crypto futures are covers the contract from the ground up.
What long and short look like on the exchange screen
In the order window of any futures exchange you will see two buttons, usually green and red, labelled something like Buy/Long and Sell/Short. Above or next to them you set the amount, and the screen shows how much margin that position will take from your balance. You pick a side, confirm, and the trade is open — the full click-by-click walkthrough lives in how to open a long position.
After that, the trade appears as a position card lower on the screen. It shows the direction (Long or Short), the size of the position, your entry price, the price the exchange uses to value it right now, and your running profit or loss in green when you are up and red when you are down. That number moves every second while the position is open, and it is not final money until you close the trade. The easiest way to see all of this for real is to sign up on Bybit and look at the order window with a small amount, or in demo mode first.
The mix-up almost every beginner has about shorts
Many people assume "short" means selling coins they already own. It doesn't. If you hold bitcoin in your spot wallet and sell it, you have simply exited — you are now holding USDT and nothing happens to you if the price keeps falling. A short on futures is an open position that keeps earning while the price goes down, and keeps losing while it goes up.
The second mix-up is thinking a short is riskier than a long because "the price can rise forever". In practice both sides behave the same way on your screen: the exchange holds part of your money as margin, and if the market moves far enough against you, it closes the position for you. How far that loss can go depends on the margin mode: with isolated margin it is usually limited to the money you set aside for that one trade, with cross margin it can reach your whole futures balance. That works the same way whichever direction you picked — the difference between the two modes is explained in cross vs isolated margin.
Picking a side is the easy part. Deciding when to be long and when to be short is the real work, and no page can hand you that. What you can do from day one is cap the damage when you are wrong: set a stop-loss before you confirm the trade, and keep the position small enough that one bad call does not hurt. Our page on when to buy and when to sell goes into reading the market.
So which one should you start with?
Most people start with longs, simply because "I think this will go up" feels more natural than the reverse. There is nothing wrong with that. Just remember that the ability to go short is half of what you are paying for with futures — otherwise you could buy the coin on spot and be done, as we compare in futures vs spot.
Before you risk anything, check that futures are available where you live — several exchanges do not offer derivatives in certain countries, and the app will tell you during sign-up. Then start with an amount you would not mind losing, and see how a real position card behaves for a few hours. The mechanics make a lot more sense once you have watched one green number turn red and back again.
Is a long position the same as buying bitcoin?
It feels similar — you profit when the price rises — but you are not buying the coin. A futures long is a contract settled in USDT: you never receive bitcoin, you cannot withdraw it to a wallet, and the position carries margin and fees that a simple spot purchase doesn't.
Do I need the full position size in my account?
No. The size you type in the order window is the size of the trade; the exchange only holds part of it as your margin, and how big that part is depends on the leverage you set — the higher the leverage, the smaller the deposit for the same trade. The order window shows the required margin before you confirm, so check that number rather than guessing.
Can I hold a long and a short on the same coin at the same time?
Many exchanges have a setting that lets the two positions sit side by side instead of cancelling out — look for it in the position settings, the name differs from app to app. For a first trade it just makes the screen confusing, so leave the default alone and hold one direction at a time.
Which is more profitable, long or short?
Neither one earns more by design. A 2% move pays the same 10 USDT on a 500 USDT position whichever side you took — what changes your result is how often you read the direction right and how big the position is.
What happens if the price goes against my position?
Your profit number turns red and grows as the move continues. If it reaches the point where your margin is nearly used up, the exchange closes the position itself. That is called liquidation, and in most cases you lose the margin behind that trade — with cross margin it can reach into the rest of your futures balance. A stop-loss set well before that point is how you choose the size of the loss yourself.
How long can I keep a long or short open?
On perpetual contracts there is no expiry date, so a position can stay open for as long as you have enough margin. You do pay or receive funding every few hours while it is open, which is a small payment between the long and short sides — worth checking before you leave a trade running for days.
