    How a Margin Call Works

    A margin call is the warning you get when a leveraged trade turns against you — your losses have eaten into the deposit (your margin) backing the position, and the exchange wants you to add more funds or risk having the trade closed for you. In crypto, that warning and the forced close often arrive almost together, sometimes within seconds. Here's exactly how it works, and how to stay out of its way.

    Where a long is liquidated under one stated model — the same one our liquidation calculator uses: linear contract, isolated margin, a flat 0.5% maintenance rate, no fees or funding. The move that ends the position is 1/leverage minus the maintenance rate: about 19.5% below entry at 5x, 9.5% at 10x, 3.5% at 25x, 1.5% at 50x and 0.5% at 100x. Zero equity (bankruptcy) sits deeper, at 1/leverage — 1% at 100x — but the exchange closes the position at the maintenance line, which at the highest levels lies inside ordinary market noise. Real venues add tiers, mark-price rules and fees, so their figures differ.

    Initial Margin

    The upfront collateral required to open a leveraged position. At 10x leverage, opening a $10,000 position requires $1,000 initial margin.

    Maintenance Margin

    The minimum collateral balance required to keep a position open. Falling below this level triggers a margin call. Typically a small percentage of notional value.

    5 Ways to Avoid a Margin Call

    Use Lower Leverage #1

    The #1 cause of margin calls is excessive leverage. At 100x, a 1% move liquidates you. At 5x, you can withstand a 20% adverse move. Start with 2x–5x as a beginner.

    Always Set Stop-Loss Orders #2

    A stop-loss automatically closes your position at a predetermined price, limiting your loss before a margin call ever triggers. Place it before you enter the trade.

    Monitor Your Margin Ratio #3

    Check your margin ratio regularly. On Binance Futures, a warning appears when the ratio approaches 100%; liquidation triggers at 100%. Bybit displays the maintenance margin rate — when it is nearly consumed, close or top up. Keeping your ratio below 80% is a safe operating zone on most exchanges.

    Risk Only 1–2% Per Trade #4

    Professional traders rarely risk more than 1–2% of their total account on a single trade. Use a position size calculator to determine your optimal trade size.

    Keep a Margin Buffer #5

    Don't use your entire balance as margin. Keep extra funds available so you can add collateral during volatile periods without needing to deposit more.

    Isolated vs Cross Margin

    Isolated Margin

    Only the collateral you earmarked for that specific trade is at risk. Margin calls trigger sooner, but losses are capped at what you staked. Recommended for beginners.

    Cross Margin

    Your entire account balance serves as collateral. Margin calls happen later (more buffer), but when liquidation hits, you can lose everything. Used by experienced traders with strict risk controls.

    Frequently Asked Questions

    What triggers a margin call in crypto?
    A margin call is triggered when your position's unrealized losses reduce your margin balance below the maintenance margin requirement set by the exchange. This typically happens during sudden price drops (for longs) or spikes (for shorts).
    What is the margin ratio and at what percentage do exchanges issue a margin call?
    The margin ratio is your maintenance margin divided by your margin balance, expressed as a percentage. On Binance Futures, a margin call warning appears when your margin ratio approaches 100%; liquidation is triggered at 100% for most contracts. Bybit uses a similar model — it alerts you when the maintenance margin rate is nearly consumed. When your ratio hits the maintenance threshold, the exchange force-closes the position. Keeping your margin ratio below 80% is a safe operating zone for most traders.
    What happens if I ignore a margin call?
    If you don't add more collateral or reduce your position after a margin call, the exchange will automatically liquidate your position. With isolated margin, the damage is contained to what you staked on that particular trade. With cross margin, the exchange draws from your full wallet to keep the position open, so ignoring the warning can drain your entire futures balance.
    Can I get liquidated without receiving a margin call warning?
    Yes. In fast-moving markets, price can gap through the margin call threshold and reach the liquidation price in milliseconds before any notification is sent. This is especially common during high-volatility events (major news, exchange outages, funding rate spikes) and at low-liquidity trading hours. Never treat a margin call notification as a safety net — use stop-loss orders set above the margin call price as your actual protection.
    Do all crypto exchanges issue margin calls?
    Most major exchanges like Binance and Bybit have margin call notification systems. However, in fast-moving markets, the price can move so quickly that liquidation happens before a margin call warning is received. Never rely solely on margin call alerts.
    Does margin mode affect when I get a margin call?
    Yes. Isolated margin triggers the warning sooner because only the collateral you earmarked for that trade is counted. Cross margin delays the alert because the exchange factors in your full available balance as a buffer — you get more time, but if the margin call eventually escalates to liquidation, the losses are far greater.

    Derivatives & Leveraged Products — Important Risk Warning

    Derivatives and leveraged products are complex and carry a high risk of rapid, substantial losses. Depending on the product and account rules, losses can exceed the initial margin or money committed. A stand-alone purchased option can lose its entire premium plus transaction costs; writing options, exercising into another position, or combining positions can create additional obligations. An uncovered call writer can face unlimited loss. Applicable legal protections can affect the loss boundary.

    You should carefully consider whether you understand how derivatives work and whether you can afford to take the high risk of losing your money. This content is for educational purposes only and does not constitute financial advice, investment advice, or a recommendation to trade derivatives.

    Legal availability and regulatory protections depend on the product, service, provider and jurisdiction. In the EU, check the applicable investment-services rules, including MiFID II where relevant, and any product restrictions. Before trading, verify with the relevant regulator whether the provider has the permissions required for the service and whether the product may be offered to you.
