Stop-Out Level in Forex (0%, 20%, 50%): How Liquidation Works

The stop-out level in forex is the exact Margin Level percentage (Equity ÷ Used Margin × 100) at which your broker's server automatically begins force-closing your open losing positions to prevent your account equity from falling into a negative balance. Depending on your broker's regulatory jurisdiction and account tier, stop-out thresholds typically sit at 50% (mandatory under FCA, ESMA/CySEC, and ASIC retail rules), 20% (common across offshore ECN brokers), or 0% (offered by Exness). Knowing how Margin Call differs from Stop-Out—and which position gets liquidated first—is essential for small-account survival.

1. The Exact Formula: Balance, Equity, Used Margin & Margin Level (%)

Every second you hold an open trade in MetaTrader 4 (MT4), MetaTrader 5 (MT5), or cTrader, the platform calculates four linked numbers in the bottom Trade bar. If you are new to collateral mechanics, review forex margin explained and margin call explained alongside these four formulas:

1. Account Balance: Your closed cash balance before counting currently open trades.
2. Equity: The real-time liquidation value of your account right now: Equity = Balance + Floating Profit − Floating Loss ± Swap/Commission
3. Used Margin (Required Margin): The collateral locked up by your broker to keep your current positions open (Notional Contract Value ÷ Leverage).
4. Margin Level (%): The health gauge that triggers Margin Calls and Stop-Outs: Margin Level (%) = (Equity ÷ Used Margin) × 100

Margin Call vs. Stop-Out Level: What Is the Difference?

• Margin Call (The Warning Light — Typically 80% to 100%): When floating losses pull your Margin Level down to the broker's Margin Call threshold (for example, 100%, meaning Equity = Used Margin and Free Margin = $0), the MetaTrader terminal highlights your balance bar in red and blocks you from opening any new positions. However, a Margin Call does not close your trades automatically.
• Stop-Out Level (Automatic Liquidation — 50%, 20%, or 0%): If the market continues moving against you and your Margin Level drops to the broker's Stop-Out percentage, the server overrides your control and automatically liquidates your open positions at the current market price.

2. Worked $200 Account Example: Step-by-Step Liquidation Order

What actually happens when you have multiple open trades and hit the Stop-Out level? Brokers do not close all of your positions simultaneously unless a massive price gap wipes out all equity at once. Instead, MetaTrader follows a strict Liquidation Waterfall: it force-closes the single position with the largest floating dollar loss first, freeing up that trade's Used Margin and immediately recalculating your Margin Level.

Let us walk through a concrete numerical example on a $200 account (see how much money to start forex trading) with 1:100 leverage, a 100% Margin Call, and a 50% Stop-Out level:

Step 1: Opening Three Trades on EUR/USD (At 1.1000)

You open three separate 0.05-lot (5,000 units each) long positions on EUR/USD (0.15 lots total = $1.50 per pip combined):

• Each 0.05-lot ticket requires $55.00 of Used Margin at 1:100 leverage ($5,500 ÷ 100).
• Total Used Margin across all 3 tickets = 3 × $55.00 = $165.00.
• Initial Free Margin = $200.00 − $165.00 = $35.00.
• Initial Margin Level = ($200.00 ÷ $165.00) × 100 = 121.2%.

Step 2: EUR/USD Drops 23.3 Pips — Margin Call Triggers (100%)

EUR/USD falls 23.3 pips without a stop-loss placement. Your combined floating loss across the three tickets is 23.3 pips × $1.50/pip = -$35.00:

• New Equity = $200.00 − $35.00 = $165.00.
• Margin Level = ($165.00 ÷ $165.00) × 100 = 100.0%.
• Your terminal flashes a 100% Margin Call warning, and Free Margin reaches $0.00.

Step 3: EUR/USD Drops to -78.3 Pips — 50% Stop-Out Liquidates Ticket #1

EUR/USD continues falling to -78.3 pips (-$39.17 floating loss on each of the three 0.05-lot tickets, or -$117.50 total floating loss):

• New Equity = $200.00 − $117.50 = $82.50.
• Margin Level = ($82.50 ÷ $165.00) × 100 = 50.0% (STOP-OUT TRIGGERED!).
• Automatic Liquidation Action: The server immediately closes Ticket #1 (the largest losing trade, realizing a -$39.17 loss).
• Post-Liquidation Recalculation: Closing Ticket #1 reduces your Used Margin from $165.00 down to $110.00 (for the remaining two tickets), while your Equity remains $82.50. Your new Margin Level jumps back up to ($82.50 ÷ $110.00) × 100 = 75.0%—temporarily saving Tickets #2 and #3 until Equity falls to $55.00 (50% of $110.00).

3. Why Exness's 0% Stop-Out Is a Double-Edged Sword

Among major regulated brokers, Exness is famous for combining high dynamic leverage with a 0% Stop-Out level. Under a 0% Stop-Out, even if your Used Margin is $165.00 on a $200.00 account, your trades are not liquidated at $82.50 (50%) or $33.00 (20%)—they remain open until your floating loss reaches -$200.00 ($0.00 Equity).

• The Advantage: If you isolate a fixed dollar risk inside a dedicated sub-account, 100% of that sub-account's cash acts as usable margin buffer, preventing premature liquidation at the bottom of a liquidity wick.
• The Danger: If you keep your entire $2,000 trading bankroll inside a single account and trade without a hard Stop-Loss order, a 0% stop-out means an unhedged losing trade will consume every last cent down to $0.00. Furthermore, regulatory investor protection mandates from the UK Financial Conduct Authority (FCA) require a mandatory 50% close-out rule and Negative Balance Protection for UK/EU retail clients specifically so traders do not lose 100% of their account on a single margin event.

Stop-Out Level in Forex: Your Questions Answered

What is the difference between a Stop-Loss and a Stop-Out in forex?

A Stop-Loss is a voluntary protective order that you place on a specific trade to cap your loss at a planned pip or dollar amount (such as 1% of your account). A Stop-Out is a mandatory emergency liquidation triggered by your broker's server when you fail to manage your losses and your overall account Margin Level (Equity ÷ Used Margin × 100) collapses to 50%, 20%, or 0%.

Which trade gets closed first when a Forex Stop-Out happens?

When your account hits the Stop-Out percentage in MetaTrader 4 or MetaTrader 5, the server automatically liquidates the open position with the largest floating dollar loss first. If closing that position restores your Margin Level above the Stop-Out threshold, your remaining positions stay open; if not, the server immediately closes the next largest losing trade.

Does higher leverage make a Stop-Out more or less likely?

For the exact same lot size, higher leverage reduces your Used Margin, which mechanically makes your Margin Level percentage higher and delays the Stop-Out trigger toward zero equity. However, in practice, inexperienced traders use high leverage to open much larger lot sizes, which multiplies their dollar loss per pip and triggers a Stop-Out in just a few pips of adverse movement.

Can my account balance go below $0.00 if a Stop-Out slips during news?

If the market gaps violently during a weekend or central bank announcement, the broker's Stop-Out market order can experience slippage in forex and fill below $0.00. That is why you should only trade with brokers offering Negative Balance Protection, which legally absorbs the deficit and resets a negative balance back to $0.00.

Why did my prop firm fail my challenge when my Margin Level was still above 1,000%?

Proprietary trading firms enforce equity drawdown rules (typically a 5% Maximum Daily Loss and 10% Maximum Total Loss), not margin stop-outs. Even if your Margin Level is 2,000%, losing 5% of your account in a single day immediately terminates the evaluation.
