TY - JOUR T1 - A Practical Approach to Liquidity Calculation JF - The Journal of Trading SP - 57 LP - 65 DO - 10.3905/jot.2014.9.3.057 VL - 9 IS - 3 AU - Oleh Danyliv AU - Bruce Bland AU - Daniel Nicholass Y1 - 2014/06/30 UR - https://pm-research.com/content/9/3/57.abstract N2 - In this article, the authors propose a new measure for liquidity that allows the user to estimate the liquidity of different instruments, regardless of exchange or the currency in which they are traded. The measure can be estimated from the order book data or by using historic measurement over the day. These two forms of the metric have proved to be well correlated with each other and allow for real-time monitoring of markets or historical calculation of liquidity. A simple liquidity algebra is considered to calculate the liquidity for portfolios of both stock and exchange-traded fund instruments.TOPICS: Accounting and ratio analysis, quantitative methods, equity portfolio management ER -
