''Intraday probability of informed trading''
( 2011, Vol. 31 No.4 )
 
 
By extending Easley, Kiefer, O'Hara and Paperman's (1996) framework to an intraday model, I empirically estimate the intraday probability of informed trading (PIN) for the 30 stocks in DJIA index. I document a U-shaped PIN pattern over the time of a day, and the consequent test validates this finding.
 
 
Keywords: Probability of informed trading, Market microstructure
JEL: G1 - General Financial Markets: General (includes Measurement and Data)
C5 - Econometric Modeling: General
