## How Does the “Stress Test” Factor into Portfolio Margin Calculations?

The stress test is a core component of portfolio margin, where the broker's system simulates various extreme market scenarios to determine the maximum potential loss of the entire portfolio. The margin requirement is then set to cover this calculated worst-case loss, ensuring the account has sufficient collateral to withstand severe market movements.

## Glossar

### [Maximum Potential Loss](https://learn.greeks.live/area/maximum-potential-loss/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Exposure ⎊ Maximum Potential Loss (MPL) within cryptocurrency, options trading, and financial derivatives represents the theoretical worst-case financial detriment an investor could incur from a specific position or portfolio.

### [Portfolio Margin](https://learn.greeks.live/area/portfolio-margin/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Margin ⎊ The portfolio margin, within cryptocurrency derivatives and options trading, represents the aggregate collateral required to maintain open positions across an entire trading account, rather than on a per-contract basis.

### [Stress Test](https://learn.greeks.live/area/stress-test/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Simulation ⎊ A stress test is a simulation technique used to evaluate the resilience of a financial institution or portfolio under extreme, adverse market conditions.

This geometric juxtaposition symbolizes the critical node where centralized limit order book dynamics meet decentralized finance settlement layers. The intersecting elements can be interpreted as the structure of a specific synthetic instrument whose payoff profile relies on the interaction between the two spheres representing underlying crypto asset holdings and strike valuations. This scenario highlights the necessity of precise execution within multi-asset collateral pools, crucial for minimizing slippage during volatile exit scenarios or during complex option exercise procedures. The interplay between shadow and intense light reflects the dichotomy between transparent blockchain verification and opaque, off-chain market making strategies. The entire composition speaks to managing counterparty risk within bespoke yield farming protocols or when determining optimal gamma scalping strategies across exchange ecosystems."
