Billy,

Stockcharts.com have recently instituted pivots on their charts. In their blog, they list their standard pivot calculation as the following:

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

Support 1 (S1) = (P x 2) - High

Support 2 (S2) = P - (High - Low)

Resistance 1 (R1) = (P x 2) - Low

Resistance 2 (R2) = P + (High - Low)

This appears different than the calculation used on this site. If true, do you happen to know why the difference?
