Lesson 9 — Leverage, Margin, MTM & Liquidation

In the previous lesson, we learned about spot, futures and perpetual contracts. Now we will understand four important concepts used in leveraged trading: leverage, margin, MTM and liquidation.

1. What Is Margin?

Margin is the amount of money or crypto that you provide as collateral for a leveraged trading position.

For example, suppose you want to take a futures position worth 10,000 USDT and the exchange requires 1,000 USDT as the required margin.

Your 1,000 USDT is supporting a position with a much larger notional value.

2. What Is Leverage?

Leverage allows you to control a larger position using a smaller amount of margin.

For example, with 10 times leverage, 1,000 USDT of margin can be used to control a position with a notional value of around 10,000 USDT, subject to the exchange's rules.

The important point is that leverage increases your exposure. It does not make the underlying asset less risky.

3. How Does Leverage Affect Profit and Loss?

Imagine you have 1,000 USDT as margin and open a 10,000 USDT Bitcoin position.

If Bitcoin moves 5 percent in your favour, the position makes approximately 500 USDT before fees, funding and other adjustments.

But if Bitcoin moves 5 percent against you, the position loses approximately 500 USDT.

This is why leverage can make both profits and losses happen much faster.

4. High Leverage Is Not Free Money

A common mistake among beginners is to think that higher leverage means higher guaranteed profit.

That is not correct.

Higher leverage means that a smaller price movement can have a larger impact on your margin.

The higher the leverage, the smaller the adverse price movement that may cause serious damage to your position.

5. What Is MTM?

MTM means Mark-to-Market.

In simple terms, MTM means calculating the current value of your open position based on the current market or reference price.

This means your unrealized profit or loss can change continuously while your position remains open.

6. Simple MTM Example

Suppose you buy a futures position when Bitcoin is at 100,000 USDT.

If the relevant price moves to 102,000 USDT, a long position will show an unrealized profit, before fees and other adjustments.

If Bitcoin falls to 98,000 USDT, the same long position will show an unrealized loss.

This changing value is part of the mark-to-market process.

7. Unrealized vs Realized P&L

Unrealized profit or loss is the gain or loss on a position that is still open.

Realized profit or loss is the gain or loss after the position has been closed.

For example, if your futures position currently shows a profit of 200 USDT but you have not closed it, that is generally an unrealized profit.

Once you close the position, the resulting profit or loss becomes realized, subject to fees and other adjustments.

8. What Is Liquidation?

Liquidation happens when an exchange automatically closes a leveraged position because the available margin is no longer sufficient under the exchange's rules.

The purpose is to prevent the position's losses from exceeding the collateral available to support it, subject to the exchange's liquidation system.

9. Simple Liquidation Example

Suppose you have 1,000 USDT of margin supporting a much larger leveraged position.

If the market moves strongly against your position, your unrealized loss increases.

When your available margin falls to the level where the exchange's liquidation rules are triggered, the exchange can automatically close the position.

You can therefore lose a large part or potentially all of the margin supporting the position.

10. Liquidation Is Not the Same as a Normal Stop Loss

A stop-loss is an order or risk-management instruction that you choose to use to limit a loss.

Liquidation is an automatic risk-control mechanism applied by the exchange when the position no longer meets its margin requirements.

A responsible trader should not plan to use liquidation as a risk-management strategy.

11. Why Does the Liquidation Price Matter?

When you open a leveraged position, the exchange normally shows an estimated liquidation price based on the position, margin, leverage and other factors.

Traders should know this price before entering the position.

But remember that liquidation price is not simply the same percentage calculation for every trade. It depends on the exchange's rules, contract, margin mode, fees and other factors.

12. Isolated Margin

In isolated margin mode, a specific amount of margin is assigned to a particular position.

This can limit the amount of your available margin exposed to that individual position, according to the exchange's rules.

13. Cross Margin

In cross margin mode, available margin in the relevant account can be shared across positions according to the exchange's rules.

This can help a position avoid liquidation in some situations, but it can also expose more of your available account balance to losses.

14. The Important Relationship

Remember this simple relationship:

Leverage → Larger position → Greater exposure → Faster P&L changes → Higher liquidation risk.

Margin provides the collateral. MTM reflects the changing value of the position. Liquidation can happen when the margin requirements are no longer satisfied.

15. What Should a Beginner Remember?

If you are new to crypto, do not start with high leverage.

First understand how the position size, margin, unrealized P&L, funding and liquidation price work.

A small position with sensible risk management is much easier to understand than a large position created using high leverage.

Key Takeaway

Leverage allows you to control a larger position with less margin, but it also increases risk.

MTM shows how the value of your open position changes as the market moves.

Liquidation is the exchange's automatic mechanism for closing a position when margin requirements are no longer met.

Before using leveraged crypto trading, understand these concepts completely. Never use leverage simply because the exchange allows it.
