## Portfolio VaR Calculation

Portfolio Value at Risk (VaR) calculation is a statistical method used to quantify the potential loss of a trading portfolio over a specific time frame. It estimates the maximum loss expected under normal market conditions with a given confidence level.

For crypto derivatives, this involves analyzing historical price data, volatility, and the correlation between different assets. It allows risk managers to understand the aggregate exposure of a portfolio to various market factors.

By setting a VaR limit, protocols can ensure that the total risk remains within acceptable bounds. It is a cornerstone of quantitative risk management, providing a standardized metric for comparison.

However, VaR can fail during extreme "black swan" events, necessitating supplementary stress testing. It remains a primary tool for capital allocation and risk oversight.
