“…Starting from the popular ROLL measure (Roll, 1984), which is based upon successive price changes, various models or proxies have been proposed to estimate intraday spread using lowfrequency data (Abdi & Ranaldo, 2017;Corwin & Schultz, 2012;Chung & Zhang, 2014;Fong et al, 2017Fong et al, , 2018Goyenko et al, 2009;Holden, 2009;Lesmond et al, 1999) and several studies have tested their performance and reported that the performance of these proxies are mostly unsatisfactory in terms of their ability to capture spread (Chung & Zhang, 2014;Cobandag Guloglu & Ekinci, 2016;Corwin & Schultz, 2012;Fong et al, 2017;Goyenko et al, 2009;Lesmond, 2005). 10 Moreover, as these proxies mostly aim at measuring daily liquidity, their utility is limited at higher frequencies.…”
