Introduction to Mark Price in Crypto Contract Trading
The financial world is undergoing rapid transformation with the emergence of digital assets, challenging traditional trading methods. As margin trading gains popularity, having a stable reference point for investment decisions becomes crucial. This is where mark price comes into play - a mechanism that accurately reflects derivatives' true value while helping traders avoid unexpected liquidations.
Understanding Mark Price: Calculation Formulas & Key Differences
Mark price serves as a reference price derived from the underlying index of derivatives. This index typically represents a weighted average of an asset's spot price across multiple exchanges.
How Mark Price is Calculated in Contract Trading
The calculation method combines:
- Spot Index Price + EMA (Basis)
- Alternative Formula: Spot Index Price + EMA [(Best Bid + Best Ask)/2 - Spot Index Price]
This dual approach helps:
- Prevent price manipulation
- Smooth out abnormal volatility
- Reduce unnecessary liquidations
Key Differences: Mark Price vs. Last Traded Price
| Factor | Mark Price | Last Traded Price |
|---|---|---|
| Calculation Basis | Weighted index + moving averages | Most recent transaction |
| Volatility Impact | Smoothed | Immediate market reaction |
| Liquidation Triggers | More stable reference | Can be manipulated temporarily |
