What is a stop out? Forced closing, and losses larger than your deposit

In forex, when losses grow, your broker may close your positions automatically, even if you do nothing. This is called a stop out. This article explains, with diagrams, how a stop out happens, how the rules differ between countries and regions, and what happens when a stop out comes too late and the loss is larger than the money you deposited. It does not tell you how to trade.

In short

A stop out is when open losses (losses on trades you have not closed yet) grow and the money left in your account falls below a set level, so the broker closes your positions automatically. Regulators in the European Union, the UK and Australia have set rules for closing positions before losses grow too large.[1][2][3] In Japan, for example, a stop out is often called a "loss cut".[5] But if price jumps suddenly, the stop out can come too late, and the loss can be larger than your deposit.[7]

What happens as open losses grow

Say you deposit 100,000 (in your account's currency) and open a trade, and the money needed to keep that position open (the required margin) is 40,000. As your open loss grows, the money left in your account shrinks.

An example with 100,000 deposited and 40,000 required margin. With no open loss, 100,000 is left and margin level is 250%. With a 60,000 open loss, 40,000 is left: 100%, and a warning comes. With an 80,000 open loss, 20,000 is left: 50%, and positions are closed automatically.
The % is "money left ÷ required margin". It does not mean half of your deposit is gone. Numbers are examples.

This % is called the margin level (money left ÷ required margin × 100). In the example, when the open loss reaches 80,000 and 20,000 is left, the margin level is 50%. By the time the positions are closed, 80% of the 100,000 deposit is gone.

The lesson on margin and margin level explains the terms and the math. To see how far price can move before your account is stopped out, use the margin level and stop out calculator.

How the rules differ by region

The stop out level, and what happens to losses larger than your deposit, depend on the rules. Here are some published rules. (The EU, UK and Australian rules are for retail clients, which covers most individual traders but not professional or wholesale clients. Japan's rules cover a broker's clients as defined in the association's rules.)

European Union

Stop out: close positions when the account's funds plus open profit or loss fall below half of the required margin.[1]

Losses beyond the deposit: the client's liability is limited to the funds in that account.[1]

This was a temporary 2018 decision by the European Securities and Markets Authority, covering CFDs (contracts where only the price difference is settled), which include forex.[1] Between 2019 and 2020, national regulators in EU countries replaced it with their own rules.[8]

United Kingdom

Stop out: close positions when funds fall to 50% of the margin needed to keep them open.[2]

Losses beyond the deposit: clients cannot lose more than the funds in their account.[2] (Made permanent in 2019.)

If a firm fails: the Financial Services Compensation Scheme (FSCS) can pay up to £85,000 per person, per firm, when a covered investment firm has gone out of business and cannot return your money. It does not pay for losses from price moves.[9]

Complaints: first complain to the broker. If you are not happy with its answer, or it has not answered within 8 weeks for most complaints, you can take the complaint to the Financial Ombudsman Service (FOS) for free.[10]

Australia

Stop out: if the money in the account (net equity) falls below 50% of the total initial margin for the open positions, the broker must close one or more positions as soon as market conditions allow.[4] The aim is to close positions before all or most of the client's money is lost.[3]

Losses beyond the deposit: limited to the funds in the account.[3] (From March 29, 2021.)

Complaints: ASIC says firms covered by its dispute resolution rules must be members of the Australian Financial Complaints Authority (AFCA), and that AFCA can handle complaints that the firm could not resolve internally.[11] Check whether the firm is an AFCA member before you rely on it.

Japan

Stop out: each broker sets its own level, above a minimum in the industry association's rules (for example, at least 15% at 25:1 leverage).[5]

Losses beyond the deposit: if a stop out closes positions at a loss larger than the deposit, the client owes the broker the difference, and brokers must explain this in advance.[5]

Countries and regions not listed here have their own rules. Even in one country, the level differs by broker and account type, and the rules that apply can depend on where the broker is registered, which may not be the country you live in. Brokers outside these rules may not offer these protections. To check your own account:

When the stop out comes too late

A stop out does not guarantee you are closed at the level. If price jumps, the trade closes at the price after the jump.

An illustrative price path for a buy position. Price jumps from just above the stop out level to well below it. The trade closes at the price after the jump, not at the level.
An example with a buy position. The horizontal line shows the price at which the margin level reaches the stop out level.

So a stop out does not promise that your loss stays within your deposit. The lesson on price gaps explains why prices jump, for example at the start of a week.

This has happened. The Swiss National Bank had a policy of not letting one euro fall below 1.20 Swiss francs, and on January 15, 2015 it announced it was ending that policy.[6] After the large price move that followed, US forex broker FXCM said its clients had significant losses and negative balances owed to FXCM of about 225 million dollars.[7]

How losses larger than your deposit are handled

When a loss is larger than the money in your account, it is handled in one of two broad ways.

An example with 100,000 deposited and a loss of 120,000. Where you pay any shortfall, the balance becomes minus 20,000 and you owe that amount. With negative balance protection, the balance stops at 0.
Amounts are examples, in your account's currency.

Things to check yourself

A stop out is set by your broker. A stop loss is an order you place yourself. You can work out how much you are willing to lose in a day with the daily loss limit calculator, and your trade size with the position size calculator. What you do is your decision; this article does not make it.
