Long, short and leverage
Long means profiting from a rise, short — from a fall, leverage — trading a bigger amount than you have. Three words you need for any futures trade. Here is, with numbers, what leverage really does and why it wipes out deposits.
What a long is
A long is a trade on a rise: buy lower, sell higher. You buy bitcoin at $100,000, it rises to $105,000 — you made 5%. That is what anyone buying a coin on spot does.
What a short is
A short is a trade on a fall: sell first, buy back cheaper. You open a short at $100,000, price drops to $95,000 — you made 5%. If price rises, you lose. On futures a short opens as easily as a long: one "Sell / Short" button.
The only difference is direction: in a long the stop loss goes below entry, in a short — above. Details in Stop loss and take profit.
What leverage is
Leverage lets you open a position larger than your money. 10× means every dollar of yours opens $10 of position. Your money in the trade is the margin, the full value of the position is the position size:
Profit and loss are calculated on the position size. Price up 3% — the $1,000 position made $30, i.e. 30% of your $100. Down 3% — minus $30, also 30% of margin.
How leverage affects profit, loss and liquidation
Leverage multiplies the result as a percentage of margin — both ways. And it has a limit: when the loss almost eats the margin, the exchange closes the position itself. That is liquidation. With isolated margin it happens about 1 ÷ leverage away from entry:
- 5× — price only needs to move ~19.5% against you;
- 10× — ~9.5%;
- 20× — ~4.5%;
- 50× — ~1.5%;
- 100× — ~0.5%, an ordinary one-minute wick.
The liquidation calculator gives the exact price for your trade.
Something beginners miss: leverage by itself does not make a trade riskier if you have a stop and size the position from risk. A $1,000 position with a 2% stop loses $20 — at 5× or at 20×. Leverage only changes how much of your money sits in margin and where liquidation is. The real danger is high leverage without a stop, with the whole deposit in one trade.
Which leverage to choose
- First choose the stop level — from the chart and volatility.
- Size the position from risk: size = risk amount ÷ distance to stop. Risk is usually 1–2% of the deposit (why — in How much to risk per trade).
- Pick leverage where margin covers that size and liquidation sits beyond the stop with room.
The position size calculator does all three steps and shows the safe leverage range.
FAQ
What are long and short in simple terms?
A long is a trade on a price rise: buy lower, sell higher. A short is a trade on a fall: sell higher, buy back lower. On futures both open with one button.
What is leverage on an exchange?
The ability to open a position larger than your money: at 10× leverage, $100 of margin opens a $1,000 position. Profit and loss are calculated on the whole position.
Why is leverage dangerous?
It multiplies the result as a percentage of margin both ways and brings liquidation closer: at 10× the position is closed after a ~9.5% move against you, at 50× after ~1.5%.
What leverage is best for beginners?
One where liquidation is well beyond the stop — most often 2–5×. More important than leverage are a stop loss and position size based on 1–2% risk.
Can I lose more than I put in?
In isolated mode, no: liquidation takes the margin of that position. In cross mode the whole account balance backs the position and you can lose more. Isolated mode is easier for beginners.
