## How Does a Centralized Exchange (CEX) Use Margin Trading in Financial Derivatives?

CEXs allow users to trade derivatives, such as perpetual futures, using borrowed funds, which is margin trading. The CEX acts as the counterparty or facilitator, providing the leverage and managing the risk.

Users deposit a small amount (initial margin) to control a much larger position. The CEX continuously monitors the user's equity against the maintenance margin and will automatically liquidate the position if the collateral falls below this threshold to prevent the CEX from incurring losses.

        "caption": "The image displays a sharply angled structure with planes of muted tan and cyan intersecting against a profound black background, dramatically highlighted by strong directional light casting severe shadows. The tan surface features a dark, centralized circular motif with a minute central node, perhaps symbolizing a governance token lock or a fixed notional value in a decentralized exchange mechanism. The sharp cyan edges suggest a distinct boundary or a high-leverage exposure profile, characteristic of sophisticated options trading strategies on crypto assets. This geometry visually abstracts the precision required in calculating Greeks for non-linear payoff structures common in crypto derivatives markets, such as analyzing vega exposure in volatile DeFi index products. The deep shadow work implies market friction or the difficulty in price discovery within opaque trading venues or when managing delta-neutral spreads against rapid price action. It represents the structural tension between the transparent, immutable nature of blockchain execution and the complex, often illiquid reality of exotic crypto derivatives settlement, requiring mastery of volatility skew and implied volatility modeling."
