Understanding the true market value of your positions is crucial for successful trading strategies. Traditional methods often rely on the last trading price to mark a position’s value and need to be more accurate in accurately reflecting the market’s true value. This discrepancy becomes especially pronounced during market manipulation, illiquidity, or abnormal volatility and can lead to unnecessary liquidations. Such challenges are more prevalent in the nascent stages of a new exchange, where liquidity is still developing.

To mitigate these issues and enhance market stability, the CVEX Protocol introduces an innovative approach to evaluating a contract’s value through the Mark Price mechanism. This article delves into the significance of Mark Price in futures and perpetual contracts trading on CVEX, highlighting its benefits and the methodology behind its calculation.

What is Mark Price?

Mark Price acts as an anchor to the market’s perception of a contract’s true value, independent of immediate fluctuations in the order book. It is a critical tool the CVEX Protocol uses to assess the value of traders’ positions in futures and perpetual contracts. By doing so, it calculates equity and maintenance margins, stabilising against market manipulation and protecting traders from unwarranted liquidations due to market anomalies.

Calculating Mark Price

Calculating Mark Price involves several steps, each designed to ensure that the final value accurately reflects the market’s consensus on a contract’s value. Here’s a breakdown of the process:

  • Index Price. The Mark Price calculation begins with the Index Price of the underlying asset, provided by the Price Oracle. This price reflects the aggregated value of the asset across multiple exchanges, serving as a reliable reference for its true market value.
  • Last Price. Concurrently, the Last Price is determined based on the CVEX order book. It is calculated as the median value between the lowest ask and the highest bid prices, averaged throughout the Index Price updates.
  • Contract Basis. The protocol computes the contract basis as a moving average of the difference between the Index Price and the Last Price. This basis reflects the market’s collective cost of carrying underlying assets, accounting for factors like time value and market expectations.
  • Mark Price Calculation. Finally, the current Mark Price is calculated by adjusting the current Index Price with the basis. This ensures that the Mark Price remains sensitive to genuine market trends while being protected against price manipulation.

MarkPrice = IndexPrice + Basis

The implementation of Mark Price in futures trading on CVEX offers several advantages:

  1. Stability. By stabilising the valuation of contracts against market anomalies, Mark Price protects traders from unnecessary and potentially harmful liquidations.
  2. Fair Valuation. It ensures that the value of positions reflects the collective perception of the true market value, free from the distortions of temporary market fluctuations.
  3. Protection Against Manipulation. Mark Price acts as a safeguard against potential market manipulation, ensuring that the integrity of the trading environment is maintained.
