There is a lot of discussion on these boards regarding Pivot Point trading and calculation and the purpose of this thread is to come to some definitive conclusions about which Pivot Point calculator and calculation method is best.
There are four (4) PP calculators on this site alone and numerous other ones available elsewhere. My question is which one has the greatest validity? Does the user input session data or 24 hour data? Do you use the close or the settlement price? What about the vaunted and somewhat secretive 'floor trader' pivots? In sum, is there a consensus (and attendant back-testing) as to which numbers and which calculator works best?
