I just went digging through a pile of pivots calculations. I'm not sure which is which as a lot of my notes are hand written. I have realticks r2 as P+(r1-s1) S2 (p-(r1-s1) The r1 and s1 were always correct but the r2, s2 were no longer correct. My math was correct so the formula must have been different then what they told me, because no new variables are introduced to the calculations. I have changed brokers and I do miss the Real Tick pivots.
You can take a look at my manual at www.sp-levels.com It was written specifically to trade a pivot points type of S&R, and should work fine with any valid S&R levels. The manual is free... Phil www.sp-levels.com
Also try using the midpoints between the daily pivot and the S1 /R1, they are quite good for choppy or gapping markets
