Quote Lifetime Efficiency measures the average duration a price quote remains valid and executable before being withdrawn, revised, or filled, particularly within crypto request-for-quote (RFQ) systems. Its purpose is to assess the responsiveness and stability of liquidity providers’ pricing, indicating their operational speed and commitment. This metric reflects quote reliability.
Mechanism
This efficiency is determined by tracking the timestamp of quote issuance and comparing it against the timestamp of its expiration, modification, or successful execution. The mechanism involves monitoring a series of RFQ interactions, recording how long a given quote remains actionable. Systems collect and analyze this temporal data to identify average quote lifetimes, their distribution, and any systematic differences across various assets, market conditions, or counterparties.
Methodology
The strategic approach utilizes this metric to optimize the timing of RFQ requests and evaluate the technical capabilities and reliability of liquidity providers. A longer, stable quote lifetime indicates robust pricing engines and deeper liquidity commitment, reducing the risk of stale quotes or last-look practices. This framework assists institutional traders in selecting efficient counterparties and designing more effective execution strategies, ultimately improving the overall quality of institutional crypto trading interactions.
Dynamic quote expiry performance is best measured by Quote Lifetime Efficiency, Adverse Selection Rate, and TWAP Slippage, all calibrated for market volatility.
