P-R, P-E, P/R-A, E-A: what are they?
These values represent the relationships between outcomes of events as ‘bits’ of information, which helps significantly with analysis when glancing over a group of filtered results. We are not really interested in the values themselves, only in the relationships between them, as these help us interpret that data together with the reactions of the markets in order to generate information that we can utilize.
P-R represents the Previous-to-Revised value relationship, whereas P-E represents the Previous-to-Expected value relationship. P/R-A represents the Previous-to-Actual or Revised-to-Actual value relationship depending on whether a revised value exists. Finally, E-A represents the Expected-to-Actual value relationship.
These relationships can either be ‘P’ for positive, ‘O’ for neutral or ‘N’ for negative. They have three different strength levels depending on various relational factors and are to be interpreted as they relate to the specified event’s EEC.
