Your terminal turns red, a banner reads Margin Call, and you brace for everything to close. Nothing does. A few minutes later half your positions vanish with no second warning.

That's the margin call vs stop out gap, and traders treat the two words as one event right up until it costs them. The first is a warning light. The second is a forced exit. On a regulated EU retail CFD account, the margin call is whatever your broker decides to flag, while the stop out is a formula ESMA standardized, and the line it fires on has nothing to do with any level you drew on a chart.

Margin level is one fraction, and everything else hangs off it

Margin is the deposit your broker locks up to hold a leveraged position open. Equity is your balance plus the floating profit or loss on open trades. Free margin is equity minus the margin already locked up.

Margin level ties them together: equity divided by used margin, times 100. MetaTrader exposes it as a plain account property, "account margin level in percents", and every warning on this page is a threshold on that one fraction. Think of it as a fuel gauge. Price moves drain it. So does opening another trade, because that locks up more margin.

A margin call is a warning your broker defines

The margin call is the amber light. It marks the level where the platform starts telling you the cushion is thin, and the regulator doesn't set it. In MetaTrader's documentation, the margin call level and the stop out level are separate account properties, each "expressed in percents or in the deposit currency" depending on the mode the broker picked.

A common setup flags a margin call at 100%, where equity equals used margin. That's a rule of thumb about broker defaults, not a law, so your own account's terms win. At the flag itself, usually nothing gets closed. With free margin at zero there's no room to open anything new, and what you get is a little warning before the next line.

The stop out is where the regulator's number lives

The stop out is the forced part. Most "forex accounts" at EU brokers are actually CFDs (contracts for difference, leveraged contracts on a price instead of the asset itself), and our breakdown of how FX and CFDs differ for EU retail traders explains why that matters. For those accounts, ESMA (the EU's securities markets regulator) standardized the line in 2018. When the sum of funds in the account and the unrealised net profits of all open CFDs falls below half of the total initial margin for those positions, the provider has to close one or more of them.

In plain English: equity under 50% of required margin, measured across the whole account and not trade by trade. ESMA's temporary decision expired on 31 July 2019, and most national regulators have adopted permanent measures at least as stringent. The UK's FCA wrote the same 50% into its own handbook, which we cover in our piece on why your stop order didn't fill where you set it.

The reasoning is in ESMA's own paper. Before the rule, some providers let clients fall to 0–30% of initial margin before closing anything, which leaves almost no buffer when a market gaps. ESMA set 50% to reduce that risk.

The cushion is smaller than the account

Here's a worked example with made-up numbers, ignoring spread, swap, and currency conversion. Equity is €2,500, and the trade is long €60,000 of notional (the full contract value) on a major currency pair. At the 3.33% rate that position locks up €2,000. Margin level: 2,500 ÷ 2,000 = 125%.

The forced-close line is half the required margin, €1,000. The cushion is €2,500 minus €1,000, so €1,500. Divide by the €60,000 notional and it's 2.5%. A 2.5% adverse move in the pair and the broker closes something, with 60% of the account already gone.

Now set a planned stop 3% away. That's a planned loss of €1,800, and the broker's line sits at 2.5%. The formula gets there first.

Position size is what decides whether a stop lands inside that cushion. Where the stop goes on the chart is a separate question from where the broker's line lands, and a trade needs both answers to line up.

A second position shrinks the cushion without a single tick

Same account. Add a €10,000 position on a listed major index at the 5% rate and another €500 gets locked up. Used margin is now €2,500 against equity of €2,500, so margin level is 100%, right where many platforms flag a margin call. Free margin is zero.

The forced-close line moved from €1,000 to €1,250 of equity. The cushion fell from €1,500 to €1,250, and price hasn't moved once.

Margin level isn't a score you check once you're in trouble. It's a fuel gauge you sit next to the whole time, and opening a trade is pressing the accelerator.

— The Tradoki desk note

Because the rule works at the account level, one trade's loss eats into the margin backing another. Which position goes first is another open question. ESMA's own FAQ says the rule doesn't prescribe which positions must be closed out, or in what order. Your winner can be closed along with your loser or instead of it, depending on your broker's terms.

A stop out is a market order, not a promised price

The 50% line says when the broker has to act. It doesn't say what price it gets. Closing happens at the market, and in a gap the market can skip straight past the line. ESMA's own paper says automatic close-out reduces, but does not eliminate, the risk of losing all or more than the initial margin.

That's why a second rule exists. ESMA calls negative balance protection a backstop for when the close-out rule does not work effectively as a result of a very sudden price movement, and points to the Euro's sudden fall against the Swiss franc in January 2015, when some retail clients without it ended up owing providers very large sums.

So the protections stack. The leverage cap limits how fast the gauge drains, the stop out closes you at 50%, and negative balance protection (total loss capped at the funds in the account) catches whatever falls through.

Outside the retail regime, the line moves

Everything above is the retail regime. ESMA's FAQ says its measures only apply to retail investors, and that professional clients don't have the same protections. A professional-status account isn't covered, and nothing in the rule reaches a broker operating outside the regime.

Whether the stop out on an account like that sits at 50%, 20%, or somewhere lower is a fact in the broker's margin policy. It isn't something to assume from a forum post.

Knowing your distance takes one subtraction

The arithmetic before a trade goes on is short. Start from the broker's stated stop-out level, 50% on a regulated EU retail account. Subtract that fraction of the margin the trade will lock up from equity, then divide by the position's notional value. The result is how far price can move against the position, as a percentage, before forced closure.

If the planned stop sits farther away than that number, either the position is too big for the stop or the stop is too wide for the account. A demo account is the cheapest place to watch the gauge fall for the first time, because the same arithmetic costs nothing there.

● FAQ

What is the difference between a margin call and a stop out?

A margin call is a warning that your margin level (equity divided by used margin) has dropped to a threshold your broker chose. A stop out is the forced closing of positions when it falls to a lower threshold. The first is a message, the second is a market order you didn't place.

At what margin level does a stop out happen?

On an EU retail CFD account, the standardized line is when your funds plus the unrealised profit or loss on all open CFDs fall below half of the total initial margin for those positions. Outside that regime, the level is whatever your broker's margin policy says, so it can be lower. Your account terms are the only reliable source.

Can I lose more than my deposit after a stop out?

Under the EU retail regime, negative balance protection caps your total liability on CFDs at the funds in your CFD trading account. ESMA describes it as a backstop for when the close-out rule fails because price moved too suddenly. Professional-status accounts and brokers outside the regime don't carry that guarantee by default.

Which position does the broker close first in a stop out?

ESMA's rule doesn't say. It requires the provider to close one or more positions when the threshold is hit, without prescribing which ones or in what order. Your broker's terms of business decide that, which is a good reason to read them before you need them.

How do I work out how far price can move before a stop out?

Subtract the stop-out fraction of the required margin from your equity, then divide by the position's notional value. That gives the adverse move, as a percentage of price, your account can absorb. Spread, swap, and currency conversion shave a little off, so treat the result as an upper bound.
