Read this before anything else

Leverage does not make a bad trade good. It makes every trade bigger — the winners and the losers equally. Most people who lose an account to leverage did not get unlucky. They used a setting they did not understand on money they could not afford to lose.

If you finish this guide and still cannot say out loud what your liquidation price is before you click, you are not ready. That is a normal place to be.

Six lessons. One idea each.

Read in order the first time. Tap a lesson to open it, answer the question, mark it done.

Spot — you buy the coin and own it. Price up 10%, your coin is worth about 10% more. Nobody can close you out. You can still lose if it falls, but only what you put in.

Spot margin — you borrow cash or coins to buy more than you can afford, and you pay interest for the loan. The loan is the risk. Fail to cover it and the exchange sells you out.

Perpetual futures — you post collateral and get a contract that tracks the coin. You never own the coin. It has no expiry date, and a payment called funding keeps it close to the real price.

In one lineSpot owns. Margin borrows. A perpetual just tracks.

A perpetual future gives you…

You never take delivery. You post collateral and hold a contract that follows the price.

You have $100. At 1× you buy $100 of coin and a 10% rise makes you about $10.

At 5× that same $100 controls $500. A 10% rise makes about $50. A 10% fall loses about $50. A 20% fall wipes the $100 out.

The extra $400 was never money in your account. It was exposure. Your downside grew by exactly as much as your upside did.

In one linePosition size = your cash × leverage. Nothing was deposited.

You post $100 at 10×. Price moves 10% against you. Ignoring fees?

10× means a 10% adverse move equals 100% of your margin. The venue closes you slightly before that.

Initial margin is the deposit needed to open. Maintenance margin is the smaller amount you must still have for it to stay open.

Isolated margin risks only the cash you assigned to that one trade. If it fails, that slice is gone and the rest of your wallet is untouched. The cost is a closer liquidation.

Cross margin lets the trade draw on your whole wallet. Liquidation sits further away — but one bad trade can spend everything, not just a slice.

In one lineIsolated protects the wallet. Cross protects the trade. Pick on purpose.

You isolate $100 out of a $1,000 account and the trade is liquidated.

That is the entire point of isolated — the damage is capped at the slice you assigned.

Long means you profit if price goes up. Short means you profit if it goes down. On a perpetual you do not need to own the coin to take either side.

Beginners get short backwards because shopping only ever trains "buy low". On a short, a falling chart is a winning chart.

Both sides can be liquidated. A short has no natural ceiling on how far price can run against it, which is why size matters even more on that side.

In one lineDirection is a choice. Liquidation applies to both choices.

You are short and the price falls.

A short profits as price falls. Perpetuals have no expiry to wait for.

When your margin falls below the maintenance level, the venue closes the position for you. You do not choose the price you get.

The rough move that wipes isolated margin is 100 ÷ leverage, in percent. 10× is about a 10% move. 5× about 20%. 2× about 50%. Fees pull that line slightly closer.

Most venues liquidate on a smoothed "mark" price built from several exchanges, not the last trade printed on your chart. A scary wick on the chart does not always liquidate you — and sometimes a calm-looking chart does.

In one lineA stop is your decision. Liquidation is the venue's. Never use liquidation as your stop.

Roughly what adverse move wipes isolated margin at 20×?

100 ÷ 20 = 5. At 20× a 5% move against you is the whole deposit.

Funding is not an exchange fee. It is a payment passed between longs and shorts to keep the contract near the spot price.

If the contract trades above spot, longs usually pay shorts. Below spot, shorts usually pay longs. Many venues settle roughly every 8 hours.

It is charged on the whole position, not on your margin. 0.03% on a $20,000 position is $6 per interval — about $18 a day, every day you hold.

In one lineFunding is rent on the position. Held long enough, it quietly eats the trade.

Funding is +0.03% and you are long $20,000. Roughly what do you pay this interval?

0.03% of $20,000 = $6. It is charged on the position, not your margin.

The words, without the costume 12 terms
Margin
The cash you post so a leveraged trade can exist. A deposit, not the size of the bet.
Notional
The full size of the position in dollars. $100 at 5× is a $500 notional.
Mark price
A smoothed price from several exchanges. This is usually what liquidates you.
Last price
The most recent trade on that book. Not necessarily the price that liquidates you.
Isolated margin
Only the cash assigned to that trade is at risk.
Cross margin
The whole wallet backs the trade. Further from liquidation, more to lose.
Maintenance margin
The minimum you must still hold for the position to stay open.
Funding rate
Periodic payment between longs and shorts on a perpetual. Not a fee to the venue.
Liquidation
The venue closing your trade because margin ran too low. You do not pick the fill.
Slippage
The gap between the price you clicked and the price you got.
Reduce-only
A switch so an order can only shrink a position, never open a new one.
Stop order
Your own exit at a level you chose. A request, not a guaranteed price.

Move the numbers until it clicks.

Round figures on purpose. Nothing connects to an exchange and nothing is sent anywhere.

01 Position & liquidation
Position size$2,500
Coin quantity25.0000
Liquidation price $80.50
Move that kills it 19.5%

Isolated margin, 0.5% maintenance, fees ignored. Real venues differ slightly — always read the liquidation price on your own ticket.

02 Size from the loss, not the slider
Risk in dollars $60.00
Stop distance5.0%
Position size$1,200
Leverage that implies 1.2×

This is the order the desk works in: decide what you can lose, then let the stop and the maths hand you the size. The leverage number is an output, never an input.

03 What holding costs you
Per interval (8h)$6.00
Per day$18.00
Over the period $126.00

Funding settles roughly every 8 hours on most venues. A negative rate means you are paid instead of charged.

Where you can actually do this.

The same product has different names, different rules and different doors depending on where you live.

Check this yourself before you sign up. Who may open an account, in which state or country, and which products they see changes often — sometimes with no notice. Every link below goes to the exchange's own page, not ours.

The order ticket, field by field

Generic on purpose — every venue styles this differently and restyles it again next quarter. All eight controls are on all of them. Tap any field to find out what it does. Nothing here is connected to anything.

Demo balance $1,000

1 The contract

BTC-USD PERP is a perpetual on bitcoin, priced in dollars. You never receive bitcoin. Check this line first — on most venues the spot ticket and the perps ticket look almost identical, and people open the wrong one.

2 Margin mode

Isolated risks only the cash assigned to this trade. Cross lets it draw on the whole wallet. Set it before you open — many venues will not let you change it on a live position.

3 Leverage

The number most people get wrong. It is a ceiling the venue allows, not a suggestion. Watch the liquidation price move as you drag it — that is the only honest readout of what you just chose.

4 Order type

Market fills right now at whatever price is there, which in a fast move is worse than the one on screen. Limit fills only at your price or better, and may never fill at all. Beginners should default to limit.

5 Price

Greyed out on a market order, because you are not choosing the price — you are accepting whatever the book gives you. That gap is called slippage.

6 Size

The trap. Many tickets show size as a percentage of your balance, so 100% looks like a full allocation rather than every dollar you own at the leverage above. Some show coin quantity, some show dollar value. Read the unit before you drag.

7 Liquidation price

The single number to read before you confirm. If you cannot see it on your ticket, find it. If the move between here and your entry looks like an ordinary day on the chart, the size is wrong.

8 Reduce-only

A safety switch: the order can only shrink a position, never open one. Tick it on every exit order and a fat-fingered stop can never flip you into a brand new trade in the opposite direction.

What you just set up

Drag leverage or size and watch the liquidation price. That is the whole lesson.

Yes. Spot margin with hourly interest on what you borrow.
Futures / perps
Yes. USDⓈ-M (stablecoin margined) and COIN-M (coin margined) perpetuals. Funding roughly every 8 hours.

The leverage slider has reached 100×+ on some bitcoin contracts. That is a product ceiling, not a setting to use. Liquidation runs on Mark price, not Last price.

Popular for its order ticket and testnet. Check Bybit's own restricted-country list before you sign up.

How accounts actually go to zero.

Rarely a mystery wick. Usually a setting that was already wrong before the wick arrived.

01 No stop, or the liquidation used as a stop

Liquidation is the venue protecting itself, not you protecting yourself. By the time it fires, the whole margin is gone.

02 Leverage picked first, size worked out after

The slider is a ceiling, not a recommendation. Decide the loss you can take, then let the maths give you the size.

03 Cross margin on a trade that should have been isolated

One bad altcoin position quietly spending a wallet that was mostly supposed to be long-term holdings.

04 Averaging down into a losing position

Adding size to be "less wrong" moves your liquidation closer while you are already losing. It is the single most expensive habit in leverage.

05 Correlated positions counted separately

Five long altcoins is not five trades. In a sell-off it is one trade at five times the size.

06 Funding ignored on a position held for weeks

A small percentage on the full position, several times a day, compounds into a real number while you wait to be right.

The rules that keep people in the game
  • Risk a fixed small slice per trade — a single number you decide once, in advance, and do not move when you feel confident.
  • The stop goes in before the entry — not after, not "when I see how it goes".
  • Obey the leverage cap you set yourself — not the one the slider allows.
  • No averaging down unless a plan you wrote beforehand says to.
  • Correlated pairs are one risk unit, not several.
  • Size to survive a losing streak, because you will have one.
A careful first week
  1. Open the account and switch margin or futures on. Do not fund it heavily.
  2. Find demo or testnet mode. Place twenty practice trades: open, set a stop, take partial profit, close.
  3. Read your own liquidation price on the ticket, every single time, before you confirm.
  4. First ten live trades at the smallest size the exchange allows. The goal is proving the process, not making money.
  5. Only then think about size — and keep the leverage where it was.
The honest version: most retail accounts that use high leverage lose money. The ones that survive are boring about risk long before they are clever about entries. If you cannot afford to lose the money, leverage is not the tool — spot is.
