# Perpetual Contract Expiry ⎊ Area ⎊ Greeks.live --- ## What is the Contract of Perpetual Contract Expiry? Perpetual contracts, unlike traditional futures, lack an expiration date, enabling indefinite position holding contingent upon margin maintenance. This structure fundamentally alters time decay considerations, shifting focus from theta to funding rates—periodic payments exchanged between long and short positions based on relative demand. Consequently, perpetual contract expiry isn’t a discrete event but a continuous process of position adjustments and funding rate calculations, influencing market pricing dynamics. ## What is the Calculation of Perpetual Contract Expiry? The determination of the perpetual contract price relies on a mechanism designed to converge with the spot price of the underlying asset, typically through a funding rate. This rate, calculated at regular intervals, reflects the imbalance between buyers and sellers, incentivizing traders to align their positions with the prevailing market sentiment. Sophisticated models incorporate order book depth and trading volume to refine funding rate predictions, impacting arbitrage opportunities and overall market efficiency. ## What is the Mechanism of Perpetual Contract Expiry? A core component of perpetual contract trading is the insurance fund, a pool of capital designed to cover liquidations and prevent cascading defaults during periods of high volatility. This fund is populated by a percentage of liquidation penalties and serves as a critical risk management tool for exchanges and traders alike, ensuring system stability. The liquidation engine, triggered when margin ratios fall below a predefined threshold, executes forced closures to mitigate potential losses, influencing market impact and price discovery. --- ## [Perpetual Futures Basis](https://term.greeks.live/definition/perpetual-futures-basis/) The price differential between an asset's spot price and its perpetual futures contract price, reflecting market sentiment. ⎊ Definition ##
