Mark Price vs. Last Price: Key Differences
Mark Price vs. Last Price: Key Differences
In cryptocurrency futures trading, understanding the difference between **Mark Price** and **Last Price** is crucial. These two pricing mechanisms serve distinct purposes: Mark Price ensures fair liquidation practices, while Last Price reflects the actual executed trade price.
What Is Mark Price?
The **Mark Price** is a calculated price that aims to prevent unfair liquidations during periods of high market volatility. It is derived from a combination of the spot market price and other factors, such as funding rates, to reflect a fair value of the contract.
- Key Features of Mark Price:**
- **Purpose:** Used to determine liquidation. - **Calculation:** Combines the spot price and a weighted index from multiple exchanges. - **Stability:** Less prone to manipulation and short-term price spikes.
What Is Last Price?
The **Last Price** is the price at which the most recent trade was executed on the exchange. It represents the actual trading activity in the market.
- Key Features of Last Price:**
- **Purpose:** Determines realized profit and loss (PnL). - **Reflects Market Activity:** Directly tied to executed trades. - **Volatility:** Can be affected by sudden market movements or low liquidity.
Key Differences Between Mark Price and Last Price
| Feature | Mark Price | Last Price |
|---|---|---|
| **Purpose** | Prevents unfair liquidations | Tracks executed trade prices |
| **Use Case** | Determines liquidation levels | Calculates realized PnL |
| **Calculation** | Weighted index of spot prices and funding rates | Based on the last executed trade |
| **Stability** | Less volatile | More volatile |
| **Manipulation Risk** | Low | Higher in illiquid markets |
Why the Distinction Matters
1. **Liquidation Protection:**
- Exchanges use Mark Price to calculate liquidation levels, reducing the risk of forced liquidation due to market manipulation or short-term price spikes.
2. **PnL Calculation:**
- Realized profit and loss (PnL) is based on the Last Price, making it critical for tracking actual trading outcomes.
3. **Strategy Alignment:**
- Understanding these differences helps traders manage risk and optimize strategies based on liquidation and execution prices.
Example of Mark Price and Last Price in Action
- **Scenario:**
- Mark Price: $20,000 - Last Price: $19,800 - Liquidation Level: Based on the Mark Price of $20,000.
- **Implication:**
- Even if the Last Price drops to $19,800, the position will not be liquidated unless the Mark Price also falls below the maintenance margin threshold.
