Mark-to-Market
Mark-to-Market is the accounting practice of recording the value of a position based on its current market price rather than its original entry price. This process ensures that the trader's account balance reflects the real-time profit or loss of their holdings.
In the context of derivatives, mark-to-market is performed continuously to determine whether a trader meets the required margin thresholds. If the market price moves, the unrealized profit or loss is immediately reflected in the account equity.
This provides transparency and allows the exchange to monitor risk accurately at every moment. For cryptocurrency derivatives, where prices change in milliseconds, this practice is essential for maintaining a fair and stable market.
It prevents the accumulation of hidden losses that could threaten the protocol. By forcing traders to recognize their current financial standing, mark-to-market encourages more disciplined and informed trading decisions.
