Calculating pivot points, resistances, and supports

I heard that the following equations are used to calculate a pivot, resistaces, and supports.



Central Pivot Point (P) = (High price + Low price + Close price) / 3

First Resistance (R1) = (2*P) - Low

First Support (S1) = (2*P) - High

Second Resistance (R2) = P + (R1-S1)
Second Support (S2) = P - (R1- S1)





But for the first equation, Central Pivot Point (P) = (High + Low + Close) / 3, what CLOSE PRICE do I have to use? The close price of 00:00 EST? The close price of London market? The close price of New York? Which one??





The following prices are today's (Dec 20) daily resistances and supports made by FXthoughts.



GBP / USD

R: 1.9770 / 1.9800-15
S: 1.9700 / 1.9670-60 / 1.9615


I was wondering how these were calculated, so I tried to find it by myself


This is yesterday's chart of GBP/USD (Time is PST)

A1 is yesterday's highest price before today's London market open.

A2 is yesyerday's highest price before today's EUR market open.


B1 is the lowest price of yesterday, but it was just after London market open

B2 is the next lowest price

These are the close prices of London, New York, EUR, 0:00 EST, and 0:00 GMT (The chart above is PST)

I went to http://www.mataf.net/en/analysis-pivot.htm to calculate the pivot points, resistances, and supports, and put every number in it, but I couldn't get
R: 1.9770 / 1.9800-15
S: 1.9700 / 1.9670-60 / 1.9615


I am so frustrated. Can anyone tell me what is wrong and how to actually calculate them? Is there any program that can automatically calculate pivot points, resistances, and supports?

I have the calculators. But what I want to know is which close, high, low price do I have to use?
