What Is Leverage in Forex? The Lot Decides, Not the Ratio

What is leverage in forex? Just a loan from the broker that lets a small deposit hold a big trade? I suppose that is an answer too. With leverage of 1:100, a deposit of $1,000 can hold a position of $100,000 — and $10 on a cent account can hold $1,000.

But for me leverage is two numbers. The first is the ratio on your account. The second is the size of your trade against your own money — and only the second one can empty the account.

This ratio does one job — it sets the margin, the part of your deposit that the broker locks while a trade is open. The table shows this for one trade: 0.10 lot of GBP/USD at 1.3470, a position worth $13,470. Look at the last column.

The margin falls from $449 to $13. The pip stays at one dollar in every row. This is my answer to the 1:100 leverage vs 1:500 question — the same trade wins or loses the same money on both accounts.

What is leverage in forex — one sum

Leverage meaning in forex — the number of dollars in a trade for each dollar of your own. The sum is short: position size divided by margin. A position of $100,000 on a margin of $1,000 is leverage of 100. Brokers write it as 1:100 or 100:1, and both mean the same thing.

How forex leverage works is also simple. You do not receive the borrowed money. The broker lets you open the full position, locks the margin and counts profit and loss on the whole $100,000 — so a price move of 1% is $1,000, your entire margin. I described the locked part in a separate article on margin in forex trading.

What does 1:100 leverage mean, then? One dollar of margin for each hundred dollars in the trade. And what does leverage in forex mean when the broker shows 1:200? It means that 0.5% of each position is locked.

What does leverage mean in forex for a small account? The same, with smaller numbers. A forex leverage ratio of 1:50 locks 2% of the position — so with 1:50 leverage a deposit of $20 can hold $1,000 of currency. This is forex leverage explained with one division. If you know the ratio, you know the margin, and nothing else.

Account leverage and real leverage

There are two kinds of leverage, and brokers advertise only one. Account leverage — the ratio in your account settings, 1:100 or 1:500. This is a limit. Real leverage — the total size of your open trades divided by the money on the account. This is what you hold right now.

Take a $1,000 account with 1:500. One trade of 0.01 lot in GBP/USD is 1,000 pounds, about $1,347. Real leverage is 1.3:1, and the 1:500 in the settings changes nothing in that trade. The same account with a full lot holds $134,700. Real leverage is now near 135:1.

So what is leverage in forex trading for, if it does not change the pip? It frees margin. A set of robots that holds many pairs at once needs free margin for each of them, and a manual trader with one small trade does not need it at all. If you open one trade at a time, a high-leverage forex account gives you room for a mistake and little more.

One pound move, four lots

Here is an example from this autumn. On 14 October 2026 GBP/USD made its low of the year at 1.3137. On 5 November the Bank of England raised Bank Rate to 4% by a vote of 8–1, and the pound traded near 1.3470 that afternoon. This is 333 pips in three weeks, a move of 2.5%.

Imagine four traders who sold at the low, each with $1,000 and no stop. The first sold 0.01 lot and is down $33, or 3.3% of the account. With 0.10 lot the second is down $333. The third sold 0.30 lot — the loss reached the whole deposit, and the broker closed the trade before the end. Then the fourth sold a full lot. His trade lasted 93 pips.

All four saw the same chart. I counted all four on a 1:1000 account. On a 1:100 account the first two results are the same to the cent, the third trade is closed earlier, and the fourth trade cannot be opened at all. On a cent account with $10 — the screen shows 1,000 cents — the shares are the same, and the first trader is down 33 cents.

The loss came from the lot. How a pip turns into dollars for each lot size is in my article on what a pip is. If you want to know your risk before a trade, you need to count the lot against the account.

Leverage 1:1000 and higher

The search queries that bring people to this page ask about leverage 1:1000 more than about anything else. So what is 1:1000 leverage? It means that $1 of margin holds $1,000 of currency — a margin of 0.1%. One standard lot of EUR/USD is 100,000 euros, about $112,200 at the rate of 1.122 on 5 November 2026. With 1:1000 leverage this lot needs $112 of margin.

Some people also search for 1:4000 leverage. The sum does not change — a margin of 0.025%, about $28 for the same lot. The pip is still $10.

With a ratio like this the margin stops working as a brake. The account accepts a trade that a move of under 100 pips can close. In my example the fourth trader had $1,000, a full lot and a margin of $131. Most brokers close trades when the money on the account falls to a set share of the margin — in the European Union the rule is 50% — so his trade was closed at $66.

What comes before that moment, the margin call, I described in another article.

There is another risk at this height. On 15 January 2015 the Swiss National Bank removed its limit of 1.20 francs per euro, and EUR/CHF fell below 1.00 within minutes. Stops did not fill at their prices. Accounts with high real leverage went below zero, and some brokers failed.

I do not know when the next move like this will come. But I am sure that on such a day a small lot protects you and a stop may not. So check whether your broker gives negative balance protection.

My robots and sixteen to one

I can show the two numbers on my own product. The Forex V Portfolio is a set of 28 robots on 14 currency pairs, and the smallest lot is 0.01. The minimum deposit I set for all 14 pairs is $800 — or $8 on a cent account, where the same lots are 100 times smaller.

Count the real leverage. If each of the 14 pairs holds one trade of 0.01 lot at the same moment, the account controls about $12,600 of currency at early November rates. Against $800 this is close to 16:1. The margin for those 14 trades on a 1:500 account is about $25, so the broker would let the same robots run on a much smaller deposit.

This $800 is there for the drawdown. My product page gives a floating drawdown of up to 25% — this is $200 on the minimum deposit, and the account has to live through it.

Most articles tell a beginner to pick a low ratio, 1:10 or 1:30, and feel safe. I do not agree. For me the ratio is a setting, and the deposit behind each 0.01 lot is the risk. The account is streamed live on our YouTube channel, so the open trades and their lots can be checked.

The regulators’ limit

Regulators do not leave this choice to the trader, and their numbers are hard to argue with. In 2018 the European regulator ESMA reported that “74-89% of retail accounts typically lose money” on leveraged contracts. It then set a limit on leverage for retail clients, added the 50% close-out rule and made negative balance protection a duty of the broker.

In the United States the rule is written as a deposit — 2% of the trade for major pairs and 5% for all other pairs. In Europe, Britain and Australia the limit for minor pairs and gold is lower, 20:1. The Australian order is in force until 23 May 2027, and the regulator ASIC reported that the net losses of retail accounts fell by 91% after it started.

This is the strongest argument against my view. If the ratio were only a setting, a lower limit would not cut losses, and it did. I suppose the reason is simple — a low limit stops the trader who does not count the lot. Outside these countries brokers offer 1:500, 1:1000 or more, and nobody sets the limit for you.

A leverage of your own

What leverage should you use? I would turn the question around and start from the loss. There are three numbers to count before a trade, and the ratio is none of them.

The first number — the money you agree to lose in one trade. On a $1,000 account 1% is $10, and on a cent account with $10 it is 10 cents. The second number — the distance to your stop in pips. A loss of $10 and a stop of 50 pips give 20 cents per pip, which is 0.02 lot in GBP/USD.

The third number — the real leverage that comes out. A trade of 0.02 lot is about $2,700, or 2.7:1.

Only now look at the ratio on the account. Any setting from 1:30 up will open this trade — the margin is $90 at 1:30 and under $3 at 1:1000. For one trade the choice between them changes nothing. For a set of robots a higher ratio leaves more free margin, and this is the one good reason to ask for it.

Leverage in forex is a short list — the ratio, the margin, the lot, the stop, the real leverage. The broker gives the first. The regulator limits it. Everything else is yours. The more attention you give to the lot and the less to the ratio, the steadier the account will be.
