What Is a Margin Call? The Warning Before Your Account Gets Liquidated
A margin call is a warning from the exchange when your margin account falls below the required level. We explain the mechanics, what happens if you ignore it, and why leverage trading demands extreme caution.
The call nobody wants to receive
When trading with borrowed money (margin / leverage), there is a term you absolutely must understand: the margin call. It is the final warning before your account can be liquidated — and misunderstanding it can wipe out your capital.
What margin trading is (a quick recap)
Margin trading is when you borrow money from the exchange to trade a larger amount than your actual capital. You put up part of your own funds as margin (collateral), and the exchange lends the rest. This is a form of leverage — amplifying both gains and losses.
What a margin call is
When a trade goes against you, the loss eats into your margin. If your margin falls below the minimum the exchange requires, the exchange issues a margin call — demanding that you:
- Add more funds to restore the margin level, or
- Close part of your position to reduce risk.
Loosely: a margin call is the exchange saying "your collateral is no longer enough — top it up, or I will be forced to act."
What happens if you ignore it
If you do not meet the margin call (do not add funds, do not reduce the position) and the market keeps moving against you, the exchange will automatically liquidate — selling your position to recover the loan. At that point:
- You can lose most or all of your margin capital.
- The forced selling happens at a bad time (price is unfavorable).
This is why liquidation is the dreaded outcome of leverage trading. A margin call is the warning before it happens.
Why leverage demands extreme caution
Margin calls reveal the inherently risky nature of leverage:
- Amplified losses: a small adverse move can quickly erode your margin.
- Time pressure: you must react fast to a margin call, usually right when the market is stressed.
- Risk of losing more than your initial capital in some cases.
Leverage turns small mistakes into disasters. This is why it is not for beginners, and requires very tight risk management.
How to avoid a margin call
- Use low or no leverage. The higher the leverage, the shorter the distance to a margin call.
- Always have a stop loss. Limit losses before they reach the margin threshold.
- Do not use all your buying power. Leave spare margin as a buffer for volatility.
- Understand the exchange''s margin requirements before entering a trade.
For most long-term investors, the safest way to avoid a margin call is... to not trade on leverage.
Conclusion
A margin call is a warning from the exchange when your margin falls below the required level — the step before your account is forcibly liquidated. It exposes the core risk of leverage: amplified losses and time pressure. Understand it to see why leverage trading demands extreme caution — or, best, to avoid it if you are not highly experienced.
