Long and Short are the first two words a new futures trader meets. A long position is a bet that the price goes up. A short position is a bet that it goes down. Both are ordinary tools, and both carry risk.

This guide explains what each one does, how profit and loss are worked out, what leverage changes, and what liquidation actually means.

What Is a Futures Position?

A futures contract lets you take a position on the price of an asset without necessarily owning the asset itself. What you hold is exposure to that price, backed by money you put up as margin, which is the collateral supporting the position. Because the position is backed by margin rather than fully paid for, the platform can close it if that margin is no longer enough.

Futures come in two forms. A perpetual contract has no expiry, and a position can be held indefinitely. A delivery contract expires on a set date and is settled then. XT Futures offers both, in USDT-margined and coin-margined versions.

The examples here use perpetual USDT-margined contracts.

A futures price tracks the underlying market closely but need not match it exactly, and the two can diverge; on perpetual contracts, funding payments between traders are what keep them aligned. That is also the difference from spot trading: a conventional spot holding gains value when the price rises, other spot strategies such as margin trading work differently again, and a futures position can be opened in either direction from the start.

What Is a Long Position?

Going long refers to purchasing a future when the trader expects its value to rise in the future. On XT, that is the [Buy/Long] side of the order form.

Here is an example, using the BTCUSDT perpetual contract:

The price rose 500 USD and the position gained 500 USD, before fees and funding. Had the price instead fallen from 5,000 to 4,500, the position would have lost 500 USD.

A long position gains when the price rises and loses when it falls.

What Is a Short Position?

If a trader expects the future price to drop, they can sell a future to go short. On XT, that is the [Sell/Short] side of the order form.

The price fell 500 USD and the position gained 500 USD, before fees and funding. Had the price instead risen from 5,000 to 5,500, the position would have lost 500 USD.

A short position gains when the price falls and loses when it rises.

How Do Profits and Losses Work?

XT publishes a formula for unrealized PnL on linear USDT-margined futures, using the mark price as the basis:

Unrealized PnL = Position Size * Order Direction * (Mark Price - Entry Price)

Term by term:

• Position Size is a quantity of the base asset, not a value in USDT. Notional value is a separate figure, contract quantity multiplied by price.
• Order Direction is 1 for a long and -1 for a short. That single sign is the only thing separating the two.
• Mark Price is a reference price, not the last traded price. It will only affect the forced liquidation price and unrealized P/L, and the realized P/L will not be affected — which is also why a position can show a small gain or loss the moment it opens.

Unrealized PnL is what an open position is worth on paper, moving with the mark price.

Realized PnL is the result after the position closes, and that is what settles in the account. The gap between them is what the formula leaves out: fees are charged on entry and exit, and on perpetual contracts funding is exchanged periodically between traders.

Funding, briefly. If the rate is positive, long positions will pay and short positions will receive the funding costs, and vice versa if the rate is negative, and funding fees are collected between users. Holding a perpetual position can therefore cost or earn a little over time.

What Does Leverage Change?

Leverage sets how much margin a given position requires, which is what lets a trader open a position larger than the cash committed to it.

Higher leverage does not automatically increase the profit or loss of an existing position. For the same position size, price movements produce the same absolute PnL. Leverage changes the margin required and the potential return or loss relative to that margin.

Both positions are the same size, so the same 1% move produces the same 100 USD gain. Only the margin behind them differs, which is why the return measured against that margin differs. The example excludes fees, funding and liquidation considerations.

Leverage still matters, in two ways. A trader who uses it to open a larger position does take on larger absolute gains and losses. And the thinner the margin behind a position, the smaller the buffer before the liquidation level, all else being equal. In other words, the higher the leverage, the greater the potential gains or losses. It is recommended that beginners choose a lower leverage multiple before opening a position to become familiar with market operations.

Margin modes. Cross margin is XT’s default. The difference between the two modes:

• Isolated margin: margin is allocated to one particular position.
• Cross margin: XT Exchange uses all of a trader’s available balance within the corresponding trading pair coin type. A liquidation can therefore cost the whole available balance of that coin type, though available funds lost in one position will not serve as margin for other cross positions.

What Is Liquidation?

Liquidation happens when a leveraged position no longer meets the required margin level. XT reduces or closes the position, so liquidation can be partial or full. Losses may consume the margin assigned to that position, and under cross margin the available balance of that coin type can be drawn on as well. Fees and funding also affect where a position ends up.

FAQs

Is a Short position riskier than a Long position?
Both involve risk, and how much depends on position size, leverage, how far the market moves and the conditions of the contract. One theoretical difference is worth knowing: a price cannot fall below zero, so the adverse move against a long has a floor, while there is no ceiling on how far a price can rise.

Does higher leverage increase my profit or loss?
Not on a position you already hold. For the same position size the absolute PnL is the same; leverage changes the margin required, so the result is larger or smaller measured against that margin. Using leverage to open a bigger position is what changes the absolute figures.

Can I adjust leverage after opening a position?
Yes. Raising leverage does not automatically reduce your margin, so adjust margin manually. Margin modes are different: those cannot be switched while a position or an open order exists.

Does a stop-loss order prevent liquidation?
No. Execution can slip in fast markets, the order can fail or fill only partially, and because liquidation is triggered by the mark price while a stop-loss defaults to the latest traded price, liquidation can come first.

If I hold a long BTCUSDT futures position, do I own BTC?
No. The contract tracks the price. Ownership is not transferred in either direction.

Directions, Not Rankings

Long and Short are directions, not rankings. One gains when the price rises, the other when it falls. What they share is that both use margin, both can be liquidated, and both are shaped by leverage and by how far the market moves.

Futures trading is “a high-risk activity with the potential for significant gains, but also the possibility of extensive losses”, and “extreme price fluctuations may lead to the liquidation of your entire margin balance”.
