PowerTrade employs a sophisticated margin methodology that provides a more capital-efficient solution compared to its competitors. In this comparison (Exchange A, Exchange B), we will examine the differences in margin methodologies and highlight the advantages of PowerTrade's approach.

Key Differences

  1. Margin Calculation Method: PowerTrade utilizes the SPAN (Standard Portfolio Analysis of Risk) methodology for its entire portfolio, which takes into account a comprehensive risk analysis of the portfolio. In contrast, Exchange A uses a Dual Margin System with Cross Margin and Isolated Margin, and Exchange B employs a Portfolio Margin methodology.

  2. Currency Denomination: PowerTrade's margin is denominated in USD, while Exchange A’s margin is denominated in the contract's base currency, and Exchange B offers margins in BTC and ETH.

  3. Scenarios and Shock Factors: PowerTrade uses nine scenarios with varying Spot Rate Inputs and Implied Volatility Inputs, accounting for both spot and volatility shocks. Exchange A and Exchange B do not provide an equivalent level of detail in their methodologies.

  4. Configurable Parameters: PowerTrade allows for configurable parameters, such as Spot Shock Factor (SSF) and Volatility Shock Factor (VSF), which can be modified in response to market conditions. Exchange A and Exchange B do not provide such flexibility in their margin systems.

  5. Treatment of Non-USD Coins: PowerTrade's margin methodology considers non-USD coins as margin cover in USD while providing the full benefit of covered call positions. This feature is not present in Exchange A’s and Exchange B’s margin methodologies.
