“…To define large transactions in futures market, we follow Frino et al (2008), who develop five trade size categories based on empirical distribution of trading volume for all transactions: first size, up to the 50th percentile; second size, from the 50th percentile up to, but not including, the 70th percentile; third size, from the 70th percentile up to, but not including, the 90th percentile; fourth size, from the 90th percentile up to, but not including, the 95th percentile; and the fifth size, which is greater than the 95th percentile.…”
