What is a margin call, and how do you avoid one?
A margin call is a warning that a leveraged trade has lost too much value, and you need to add funds or the platform will close the position for you. This guide explains what triggers a margin call, how it differs from liquidation, and the practical ways to avoid one. No experience required.
01 The basics
What is a margin call?
A margin call is the moment your trading platform tells you that a leveraged position has lost too much, and you need to top up your funds or it will step in.
When you trade with leverage, part of your position is borrowed. The platform lets you borrow on the condition that you keep a minimum amount of your own money backing the trade. That minimum is called the maintenance margin. As long as your funds stay above it, the trade runs normally. When losses drag you below it, the platform issues a margin call.
Think of it as a line in the sand. Your own money in the trade is the cushion protecting the borrowed part. A margin call fires the moment that cushion gets too thin.
Equity
The portion of the position that is actually your own money, after accounting for what you borrowed.
Maintenance margin
The minimum amount of your own funds the platform requires you to keep backing the trade.
Margin call
The warning that fires when your equity falls below the maintenance margin.
02 How it works
What triggers a margin call
A margin call is triggered by one thing: your losses pushing your own funds below the maintenance margin. Leverage is what makes that happen fast.
Here is a plain example. Say you have $100.00 and use 10x buying power, opening a $1,000.00 position. Of that, $900.00 is borrowed and $100.00 is yours. Because leverage multiplies every move, a small drop in the asset becomes a large drop in your own money. If the asset falls 5%, the position loses $50.00, which is half of your $100.00 gone. If it falls 10%, your entire $100.00 is wiped out.
Somewhere along that slide, before your money hits zero, the platform draws its maintenance line and issues the call. The higher your leverage, the closer that line sits to your starting point, and the smaller the move needed to reach it.
Open the trade
You deposit your own funds and the platform adds borrowed buying power.
The market moves against you
Losses come out of your own money first, not the borrowed part.
Equity falls to the line
Your funds drop toward the maintenance margin.
Margin call
The platform warns you to add funds or cut the position.
You decide
Top up, reduce, or do nothing and risk the platform closing it for you.
03 What to know
Margin call vs liquidation
A margin call and a liquidation are two points on the same path, and it helps to know the difference.
A margin call comes first. It is the warning stage, where you still have room to act. You can add funds to rebuild your cushion, or close part of the position to reduce how much you have borrowed. Either move can pull you back above the maintenance line and keep the trade alive.
Liquidation is what happens if you do nothing and losses keep growing. The platform closes your position automatically to recover the money it lent you. In crypto markets, which trade around the clock, this can happen quickly, sometimes within minutes, because prices never stop moving. Many new traders are surprised by how fast the gap between a call and a liquidation can close.
Whether you can lose more than you deposited depends on the product. On many platforms your loss is capped at the funds you put in, because the position is closed before it goes further. Some leveraged products can lose more than your deposit, so always check the specific rules of the platform you use before you trade.

How to avoid a margin call
You cannot remove the risk of a margin call while using leverage, but you can give yourself far more room to avoid one. These are habits, not guarantees.
The simplest lever is leverage itself. Lower multipliers, like 2x or 3x, leave much more distance between your entry and the maintenance line, so an ordinary price swing will not trigger a call. Maximum leverage does the opposite: it puts the line right next to you.
A stop-loss order is your second tool. It closes a trade automatically at a price you choose, on your terms, before the platform reaches its own liquidation trigger. Setting one means you decide where the trade ends rather than the market deciding for you.
The rest is buffer and attention. Leaving some funds unused in your account gives you something to absorb a call with, instead of scrambling. And because leveraged positions move faster than plain ones, checking them regularly matters: a trade that looked safe at open can reach the line within hours.
Use less leverage
Lower multipliers leave more room before the maintenance line.
Set a stop-loss
Close the trade on your terms before liquidation.
Keep a cash buffer
Unused funds let you answer a call without a scramble.
Check your positions
Leveraged trades move fast, so watch them.

FAQ
What triggers a margin call?
Losses that push your own funds below the platform's maintenance margin. The borrowed part of your position stays fixed, so losses eat into your money first. Once your equity falls under the required minimum, the call fires.
What is the difference between a margin call and liquidation?
A margin call is a warning that still lets you act by adding funds or reducing the position. Liquidation is when the platform closes the trade automatically to recover what it lent, and it happens if you do not resolve the call in time.
How do I avoid a margin call?
Use lower leverage so an ordinary price move does not reach the maintenance line, set a stop-loss to exit on your own terms, keep some unused funds as a buffer, and check leveraged positions often because they move quickly.
Can I lose more than I deposited from a margin call?
It depends on the product. On many platforms your loss is capped at your deposit because the position is closed before it goes further. Some leveraged products can lose more than you put in, so check the specific rules before you trade.
