## House Rules

House rules are the internal margin policies set by a broker that are often stricter than regulatory minimums. Brokers adjust these based on their assessment of market risk and their own risk tolerance.

Traders must comply with both regulatory and house margin requirements. Being aware of house rules is vital as they can change quickly, especially during high volatility.

These layers alternate in color, including dark navy blue, light green, and a pale cream shade, creating a sense of depth and encapsulation against a solid dark background. This abstract composition serves as a powerful metaphor for complex financial engineering in decentralized finance DeFi. The innermost core represents a core synthetic asset or a yield-generating position, requiring robust protection. The surrounding nested layers symbolize a multi-tiered risk management framework, where each layer provides collateralization and hedging against specific market risks. This layered approach is characteristic of structured products and derivative instruments, illustrating how complex protocols create risk stratification to manage volatility and mitigate counterparty risk. The design visualizes the composability of smart contracts and a robust collateral management system essential for stable liquidity provision within the ecosystem."
