Never use full margin
Committing 100% of your account as margin at 1:1000 means a 0.1% adverse move wipes you out. Professional traders rarely exceed 5–10% of their account on any single position, regardless of available leverage.
Leverage, explained
1:1000 leverage means every £1 controls £1,000 of exposure.
It is the most aggressive leverage ratio available in retail trading. Used carefully, it gives small accounts access to large markets. Used carelessly, it can erase an account in seconds. This page explains exactly how it works — and exactly what is at stake.

What leverage actually means
Leverage is borrowed exposure. You deposit a small amount of capital — called margin — and your provider lets you control a much larger position. The ratio between your deposit and your total exposure is the leverage ratio.
At 1:1000, every £1 you deposit controls £1,000 of market exposure. A £100 deposit gives you command over a £100,000 position. The magnification works in both directions: gains are amplified, and so are losses — often faster than beginners expect.
Margin
The deposit you put down — your skin in the game.
Notional value
The full size of the position you control.
Liquidation
The point where your margin is exhausted and the position is closed.
The magnification
At 1:1000, a 0.1% market move equals 100% of your margin.
This is the single most important number on this page. Major indices routinely move 0.1% within minutes. A single economic data release can move them 1% or more. At 1:1000 leverage, that routine 1% move is a 1,000% change in your account.

Comparison
Leverage levels, side by side
The same £1,000 account, the same 1% market move — five different outcomes. Notice how the jump from 1:100 to 1:1000 is not incremental: it is a tenfold increase in an already extreme position.

How to read these numbers
Each figure updates in real time as you adjust the controls. Here is what each one means — and why it matters.
- Position value — the total market exposure you control. At 1:1000, even a modest deposit commands a very large position.
- Margin required — the deposit locked up to open the position. This is your capital at direct risk.
- P&L — your profit or loss based on the market movement. Note how quickly it scales relative to your account size.
- Move to wipe account — the percentage adverse move needed to erase your entire deposit. At 1:1000 with full margin, this can be as little as 0.1%.
- Margin level — equity as a percentage of margin used. Below 100% triggers a margin call; at 0%, the position is liquidated.
Risk awareness
Why 1:1000 demands more respect than any other ratio
At lower leverage, a bad trade costs you money. At 1:1000, a bad trade can cost you your entire account — and in fast-moving or gapping markets, potentially more. The three disciplines below are not suggestions. They are the difference between surviving and not.
Use guaranteed stop-losses
At 1:1000, slippage on a standard stop-loss can be catastrophic. A guaranteed stop-loss costs a small premium but ensures your position closes at the exact level you set — even if the market gaps through it.
Assume gaps will happen
Markets gap overnight, on weekends, and on news. A 2% gap against a 1:1000 position is a 2,000% loss — twenty times your account. If you cannot afford the worst-case gap, the position size is wrong.
Worked examples
Three traders, same market, three outcomes
Three traders start with the same £1,000 account in the same market. The outcomes diverge drastically based on leverage choices, position sizing, and market conditions. The numbers speak for themselves.
Disciplined
The careful trader
1:10 leverage · 10% margin used
Account
£1,000
Margin used
£100
Position value
£1,000
Market move
+1.0%
Result
+£10 · +1%
A modest gain on a modest risk. The account is intact, the trader is in control, and there is room for many more trades — including losing ones. Position sizing is the foundation of survival.
Overleveraged
The reckless trader
1:1000 leverage · 100% margin used
Account
£1,000
Margin used
£1,000
Position value
£1,000,000
Market move
−0.15%
Result
−£1,500 · −150%
Account liquidated. This illustrates position sizing failure: at maximum leverage and margin, a routine 0.15% intraday fluctuation is mathematically unsurvivable. The position was doomed from the moment it was opened.
Margin call
The overnight gap
1:500 leverage · 50% margin used
Account
£1,000
Margin used
£500
Position value
£250,000
Market gap
−0.5%
Result
−£1,250 · −125%
The market gapped overnight on news, skipping straight past the stop-loss. This illustrates slippage (gap risk): the position was moderate, but a structural market gap rendered the stop-loss useless, filling the order at a catastrophic price.
Two distinct paths to zero
The red and yellow scenarios demonstrate that high leverage presents more than one existential threat. The reckless trader was destroyed by intraday exhaustion — the position was so large that a minor market fluctuation wiped the margin. The overnight gap trader was destroyed by slippage — the position was moderate, but a market gap rendered their stop-loss order useless. Understanding both mechanics is essential before deploying high leverage in live markets.

Frequently asked
Questions about 1:1000 leverage
If your question is not here, the full curriculum includes a longer Q&A module on leverage and margin mechanics.
Is 1:1000 leverage legal for retail traders?
In the UK and EU, leverage for retail traders is capped by regulation at much lower levels — typically 1:30 for major forex pairs, 1:20 for indices, and 1:2 for cryptocurrencies. 1:1000 leverage is available in certain jurisdictions outside these regulatory frameworks, typically through offshore brokers. The fact that it is available does not mean it is appropriate: the FCA and ESMA restricted leverage precisely because the vast majority of retail traders lose money at high ratios.
How much can I lose at 1:1000 leverage?
If you use 100% of your account as margin, a 0.1% adverse market move wipes your entire account. In volatile or gapping markets, losses can exceed your deposit — meaning you could owe money to your broker. Guaranteed stop-loss orders are the only reliable way to cap this downside, but they come at a cost and may not be available on all instruments or during all market conditions.
Why would anyone use 1:1000 leverage?
The legitimate use case is narrow: it allows traders with very small accounts to access markets that would otherwise be inaccessible, by reducing the minimum position size. A £10 deposit at 1:1000 controls £10,000 of exposure. The danger is that most traders interpret "available" as "recommended" and use the full ratio on positions that are far too large for their account. Professional traders who have access to 1:1000 rarely use more than a fraction of it.
What is a margin call?
A margin call occurs when your account equity falls below the maintenance margin — the minimum required to keep your position open. At that point, your broker will either ask you to deposit more funds or will begin closing your positions automatically. At 1:1000 leverage, the margin call level and the liquidation level are exceptionally close together — often just 0.05% apart in market terms — leaving you almost no time to react.
Does higher leverage mean higher risk?
Not automatically. Leverage is a tool; risk is determined by position size. A trader using 1:1000 leverage but only committing 0.1% of their account as margin takes on the same market risk as a trader using 1:1 leverage with 100% of their account. The danger of high leverage is psychological, not mechanical: it makes it easy to take on far more risk than you intend, because the margin requirement feels small relative to the exposure.
Can I start trading with 1:1000 leverage immediately?
We strongly recommend against it. If you are new to leveraged trading, complete the full curriculum first, then practice on a demo account for at least three months, and only consider live trading with money you can afford to lose entirely. 1:1000 leverage is not a starting point — it is an endpoint that most traders should never reach, and many experienced traders choose never to use.
Understand the power.
Respect the risk.
1:1000 leverage is not inherently good or bad — it is a tool that amplifies whatever discipline or recklessness you bring to it. The curriculum teaches the discipline.
