Hi, I want to make a PCF for RMI(4,2).  Any help would be much appreciated.

Please try the following Indicator Formula:

momentum index

100 * (ABS(C > C2) * (C - C2) + .75 * (ABS(C1 > C3) * (C1 - C3) + .75 * (ABS(C2 > C4) * (C2 - C4) + .75 * (ABS(C3 > C5) * (C3 - C5) + .75 * (ABS(C4 > C6) * (C4 - C6) + .75 * (ABS(C5 > C7) * (C5 - C7) + .75 * (ABS(C6 > C8) * (C6 - C8) + .75 * (ABS(C7 > C9) * (C7 - C9) + .75 * (ABS(C8 > C10) * (C8 - C10) + .75 * (ABS(C9 > C11) * (C9 - C11) + .75 * (ABS(C10 > C12) * (C10 - C12) + .75 * (ABS(C11 > C13) * (C11 - C13) + .75 * (ABS(C12 > C14) * (C12 - C14) + .75 * (ABS(C13 > C15) * (C13 - C15) + .75 * (ABS(C14 > C16) * (C14 - C16) + .75 * (ABS(C15 > C17) * (C15 - C17) + .75 * (ABS(C16 > C18) * (C16 - C18) + .75 * (ABS(C17 > C19) * (C17 - C19) + .75 * (ABS(C18 > C20) * (C18 - C20) + .75 * (ABS(C19 > C21) * (C19 - C21) + .75 * (ABS(C20 > C22) * (C20 - C22) + .75 * (ABS(C21 > C23) * (C21 - C23) + .75 * (ABS(C22 > C24) * (C22 - C24) + .75 * (ABS(C23 > C25) * (C23 - C25) + .75 * (ABS(C24 > C26) * (C24 - C26) + .75 * (ABS(C25 > C27) * (C25 - C27) + .75 * (ABS(C26 > C28) * (C26 - C28) + .75 * (ABS(C27 > C29) * (C27 - C29) + .75 * (ABS(C28 > C30) * (C28 - C30) + .75 * (ABS(C29 > C31) * (C29 - C31) + .75 * (ABS(C30 > C32) * (C30 - C32) + .75 * (ABS(C31 > C33) * (C31 - C33) + .75 * (ABS(C32 > C34) * (C32 - C34)))))))))))))))))))))))))))))))))) / (ABS(C - C2) + .75 * (ABS(C1 - C3) + .75 * (ABS(C2 - C4) + .75 * (ABS(C3 - C5) + .75 * (ABS(C4 - C6) + .75 * (ABS(C5 - C7) + .75 * (ABS(C6 - C8) + .75 * (ABS(C7 - C9) + .75 * (ABS(C8 - C10) + .75 * (ABS(C9 - C11) + .75 * (ABS(C10 - C12) + .75 * (ABS(C11 - C13) + .75 * (ABS(C12 - C14) + .75 * (ABS(C13 - C15) + .75 * (ABS(C14 - C16) + .75 * (ABS(C15 - C17) + .75 * (ABS(C16 - C18) + .75 * (ABS(C17 - C19) + .75 * (ABS(C18 - C20) + .75 * (ABS(C19 - C21) + .75 * (ABS(C20 - C22) + .75 * (ABS(C21 - C23) + .75 * (ABS(C22 - C24) + .75 * (ABS(C23 - C25) + .75 * (ABS(C24 - C26) + .75 * (ABS(C25 - C27) + .75 * (ABS(C26 - C28) + .75 * (ABS(C27 - C29) + .75 * (ABS(C28 - C30) + .75 * (ABS(C29 - C31) + .75 * (ABS(C30 - C32) + .75 * (ABS(C31 - C33) + .75 * (ABS(C32 - C34))))))))))))))))))))))))))))))))))

Thank you Bruce!

Hi, I am trying to learn about RMI and I would need a PCF for RMI(20,3).  Please help. Thanks.

If you are really looking to learn more about the RMI instead of just getting the formula, you might want to read through the momentum index topic referenced in my original response or seach the internet.

You can extend the pattern in both the numerator and denominator further if you need a more accurate version of RMI(20,3), but this is the longest version which is short and fast enough to be practical or post in the forums:
