What Is Leverage in Trading? The Multiplier That Cuts Both Ways
Every blown-up account has the same autopsy: the idea was survivable, the size wasn't. Leverage is the multiplier that decides which one you're running — here's exactly how it works.
By Pavel Penev, MScFounder, TradeWize · 10+ years trading the marketsThe short answer
Leverage lets you control a trading position much larger than the money you put in: you post a deposit (the margin) and trade a multiple of it. At 10× leverage, your $1,000 moves like $10,000 — every 1% the market moves, your account moves 10%, in whichever direction the market picks. It multiplies gains and losses identically, and at 10× a 10% move against you wipes the account to zero.
Three traders buy the same asset on the same morning, each with the same $1,000. By lunch the market has dipped 5% — the kind of dip that happens dozens of times a year and means nothing. The first trader, unleveraged, is down $50 and mildly annoyed. The second, trading at 10×, is down $500 — half the account, gone on a wiggle. The third, at 20×, is getting acquainted with the word "liquidated": the position closed itself, the whole $1,000 is gone, and the market hasn't even done anything interesting yet. Same idea, same asset, same morning. The only thing that differed was leverage.
That's the entire subject in one paragraph, honestly. Everything below is the mechanics of it — what the multiplier actually is, the one line of arithmetic that decides whether your account survives, where leverage shows up (sometimes without asking), and why the professionals who use it every day treat it with roughly the caution of a chainsaw.
What leverage actually is
In everyday investing, money and exposure are the same number: put $1,000 into an index fund and you own $1,000 of it. Leverage breaks that link. You hand your broker a deposit — the margin — and trade a position several times its size. Put down $1,000 at 10× and you're running a $10,000 position; the full amount your position controls is called the notional value. The broker isn't being generous. Your deposit exists to absorb the position's losses, and the moment it can't, the arrangement ends — abruptly, and not in your favour.
Leverage and margin: same deal, described from opposite ends
Margin is the deposit; leverage is the ratio. Put down $1,000 to control $10,000 and your margin is 10% while your leverage is 10× — two ways of describing one arrangement. Brokers tend to advertise the leverage and whisper the margin, for the same reason casinos put the jackpot on the poster and not the odds.
The math, both ways
The rule fits on a napkin: your account moves by the market's move times your leverage. At 10×, a 1% rise in the market is a 10% gain on your money; a 3% rise is 30%. This is the half of the equation the marketing is built on, and to be fair, it's real — leverage is one of the few things in finance that works exactly as advertised. The catch is that it has no idea which direction it's advertising.
The same routine 5% move, felt three ways. Unleveraged, it's ±5% — a shrug. At 5×, it's ±25%. At 10×, it's ±50% of your account, up or down, decided by which way an ordinary Tuesday happens to lean. The multiplier is perfectly symmetric; your feelings about it won't be.
Leverage is an amplifier: it doesn't care what song you play through it. A good trade gets louder, a bad trade gets louder, and an ordinary market wobble — the background noise every market produces for free — gets louder too. Traders don't usually get destroyed by being spectacularly wrong; they get destroyed by being slightly wrong at high volume.
The wipe-out line: 100 divided by your leverage
Here's the arithmetic that should be on the poster. Your deposit absorbs the position's losses, so the account hits zero when the market moves 100 ÷ leverage percent against you. At 2×, that's a 50% move — a genuine catastrophe, years-of-crisis territory. At 10×, it's 10% — a bad week in a volatile market. At 100×, it's 1% — a move most markets produce before breakfast. High leverage doesn't just raise the stakes; it shrinks the distance between you and zero until routine noise is fatal.
The survival math, drawn. Each step up in leverage pulls the wipe-out line closer, and past roughly 20× it enters the shaded zone — the size of move markets routinely make in a normal week. A 100× position isn't a bold bet on direction; it's a bet that the next 1% of noise happens to lean your way.
Margin call vs. liquidation — the polite warning and the trapdoor
As losses eat your deposit, the broker first asks you to top it up — the famous margin call (the broker doesn't call to chat). Ignore it, or lose money faster than you can answer, and the broker force-closes the position at the market price — liquidation. It isn't personal and it isn't optional: the broker is making sure the loss stays yours rather than becoming theirs. By design, it tends to happen at the worst price of your week.
You have $1,000. Pick a leverage and a market move, and watch the multiplier work. The whole calculation is account move = leverage × market move.
Illustrative — funding costs, fees and slippage are ignored, and real brokers liquidate a little before your equity hits zero, to make sure the loss stays yours. Now tap Crypto perp · 100×: a −1% move — ordinary pre-breakfast noise — takes the whole stake. Then set the same leverage with the move +1% and notice the win is exactly as big as the loss was. The dial has no opinion about direction. Your position size is the only thing here you actually control.
It works short, too
Everything above is direction-neutral, which is worth spelling out: leverage isn't a bulls-only product. A short position — betting the price falls — amplifies exactly the same way, so a 10× short gains 10% for every 1% the market drops and loses 10% for every 1% it climbs. The wipe-out line doesn't move either: 100 ÷ leverage, just measured upward. Markets can rally as rudely as they crash, and a leveraged short in a rising market has the same survival math as a leveraged long in a falling one.

Leverage isn't a single product you go and buy — it's a feature baked into half the instruments on a trading app, at very different strengths. The map matters, because the difference between 2× and 100× isn't a detail; it's the difference between a rough month and a liquidation email.
The retail leverage spectrum, roughly to scale. The left end is a regulated loan; the right end is an offshore exchange letting you trade 100 times your deposit on the most volatile asset class in finance. Note the axis — every step rightward pulls the wipe-out line closer.
| Instrument | Typical retail leverage | How it arrives | The catch |
|---|---|---|---|
| Stock margin account | Up to 2× (US Reg T) | A literal loan from your broker | Interest accrues daily; margin calls if equity falls below ~25% |
| Leveraged ETFs | 2–3× the index's daily move | Derivatives inside the fund | Daily reset causes volatility decay — long holds quietly bleed |
| Futures | Often ~10–20× | A small margin deposit controls the full contract | Marked to market nightly; losses are collected daily |
| CFDs (EU/UK retail) | 30:1 on major FX, down to 2:1 on crypto | A broker contract mirroring the price | Overnight funding fees; banned for US retail |
| Retail forex (US) | 50:1 majors, 20:1 others | A 2–5% security deposit | An ordinary currency wiggle becomes a huge account swing |
| Crypto perpetuals | Up to 100×+ offshore | Exchange margin, often cross-collateralised | A ~1% move can liquidate; funding rates tick constantly |
Approximate, and deliberately so — exact figures vary by broker, asset and regulator. The point is the range: the same word covers a conservative 2× loan and a 100× coin-flip.
Two of these deserve their own reading. Futures are the purest expression of leverage — the deposit is a performance bond and losses are settled every single night — and our futures guide walks through that machinery, including the day oil traded at minus $37. And leveraged ETFs are the trap for long-term investors specifically: the 2–3× applies to each day's move and resets nightly, which means over months the compounding grinds you down even when the index goes nowhere. Our ETF types guide covers that failure mode properly. The one-line summary: leverage plus time plus volatility is a tax.
What it costs to hold
Leverage is also rented, not free. A margin loan charges interest daily, at rates that would make your mortgage blush. CFDs and forex positions charge overnight funding — a small nightly fee for the exposure you're borrowing — which rounds to nothing on a two-day trade and quietly becomes real money over months. Futures embed their financing cost into the price itself, and leveraged ETFs charge fees on top of their decay. None of these costs is dramatic on its own. All of them share a direction: against you, every day you hold.
Why regulators keep capping it
Regulators have looked at retail leverage and, with unusual global consensus, reached for the dial. In the US, stock margin has been capped at 2× since Regulation T, and retail forex is limited to 50:1 on major pairs via minimum security deposits. In the EU and UK, regulators capped retail CFD leverage on a sliding scale matched to volatility — 30:1 for major currency pairs down to 2:1 for crypto — and required negative balance protection, so a retail account can't go below zero. Those rules arrived in 2018 after regulators watched what unrestricted leverage did to retail accounts, and the EU rules came with a memorable disclosure requirement: every CFD broker must now print, on its own marketing, the percentage of its retail accounts that lose money. The figures routinely land around three-quarters.
The professional's answer: size, not conviction
Here's the twist in the tale: professionals use leverage constantly, and almost never the way beginners imagine. To a professional, leverage is a capital-efficiency tool — a way to run a position without parking the full notional in the account — not a way to run the biggest position the broker will allow. The risk decision is made somewhere else entirely: at the stop. A disciplined trader decides where the trade is wrong first, then sizes the position so that being wrong costs a fixed, boring fraction of the account — commonly around 1%. Do that, and the leverage number on the ticket becomes almost incidental; the size did the risk management.
Amateurs ask how much they can control. Professionals ask how much they'll lose when they're wrong — and size the position so the answer is boring.
So should you use it?
Not while you're learning — and afterwards, less than the broker offers. That's not moralising; it's the arithmetic above. Low leverage gives your decisions room to be temporarily wrong, which every trading decision occasionally is, and high leverage hands the verdict on your idea to whichever way the next hour of noise leans. The multiplier is neutral. It will faithfully amplify skill you don't have yet just as loudly as skill you do — and it charges rent either way. If you want to feel what 10× actually does to an account, do it somewhere a liquidation costs you nothing: run the dial above, then trade it with virtual money until a 50% swing stops being a surprise.
What does 10× leverage mean?
It means you control a position ten times your deposit: $1,000 down runs a $10,000 position. Every 1% the market moves, your account moves 10% — in either direction. It also means a 10% move against you wipes the deposit entirely, because 100 ÷ 10 = 10%.
Is leverage the same as borrowing money?
Sometimes literally — a stock margin account is a real loan with real interest. In futures, CFDs and forex, nothing is lent outright; you post a deposit and the broker gives you exposure to a larger notional. Economically it behaves the same way: amplified gains, amplified losses, and a cost to hold.
What's the difference between leverage and margin?
They describe one arrangement from opposite ends. Margin is the deposit you put down; leverage is the ratio between your position and that deposit. A 10% margin requirement and 10× leverage are the same fact — brokers usually advertise the ratio and footnote the deposit.
What is a margin call, and what is liquidation?
A margin call is the broker telling you your deposit has worn too thin — add money or reduce the position. Liquidation is what happens if you don't, or if the market moves too fast for the question: the broker force-closes your position at the market price to stop the loss growing beyond your deposit.
Can you lose more than you deposit with leverage?
It depends on the instrument and where you trade. EU and UK retail CFD accounts have negative balance protection, so losses stop at zero. Futures and US margin accounts have no such floor — a fast gap through your liquidation price can leave you owing the broker money on top of a wiped account.
What leverage should a beginner use?
As little as possible — 1× to 2× while learning, and ideally none until you've traded a realistic simulator long enough to watch leverage work in both directions. The honest tell: EU brokers must publish the share of their retail clients who lose money on leveraged products, and it's typically around three-quarters.
Why do regulators cap leverage?
Because the wipe-out math is brutal at retail-typical sizes: at 100×, routine daily noise is fatal. Regulators cap leverage in proportion to each asset's volatility — the EU allows 30:1 on stable major currency pairs but only 2:1 on crypto — so a routine move produces a survivable loss instead of a zeroed account.
Feel 10× before it costs you anything
Reading the wipe-out math is one thing; watching it happen to a position is another. TradeWize's futures track lets you trade leveraged markets with virtual coins on live-feel charts — margin calls, liquidations and all — so the lesson lands before the money's real.
