Could you help me with a pcf please.
Presently have a pcf which modifies a 2 day tsv. This is
(2*TSV1 +(2*TSV1.1+(2*TSV1.2+(TSV1.3+TSV1.4)/3)/3)/3)/3
I would like to have another pcf based on 13 day TSV using the same principle as the above pcf

Your formula appears to be creating a weighted average of a TSV of 1. I am not sure what makes this a modified 2-day TSV. If anything each plot includes 5-bars of TSV (back to TSV1.4).
I need to you to explain more what you are trying to do.

rayok,
Your request is like asking what is the next term of 1,2,3,4,.... It is impossible to to tell, but most would guess it is 5.
Your PCF looks like an attempt to approximate
XAVG(TSV1,2)
Thus,
XAVG(TSV1,13)
is likely a good approximation to the PCF you are looking for.
Thanks,
Jim Murphy

Craig,
The pcf given is by Elder as the Tc 2000 equivalent of his 2 day EMA of Force Index
Elder also talks about a 13 day EMA of Force Index and that is what I am trying to achieve
As you can see I am no genius when it comes to creating or understanding pcf's

I think you have something confused.
This is the formula for his Force Index (not in PCF syntax):
EFI = AVG( VOL * (CL - CL.1) )
To add his force index to your chart create a custom indicator with these settings:
Visible (checked)
Center Zero Line (checked)
Smoothing Average (2 or 13 or whatever)
Simple (selected)
Indicator Formula:
V*(C-C1)
I was suprised, in me research, to find it was a simple average.
Again, I don't see anything in my searching that implies TSV is part of his force index.

My research differed from Craig's in that it seemed to indicate an Exponential Average is the more common method. If that is what you prefer, just follow Craig's directions to plot the indicator except change the Average Type to Exponential.
If you want to write Personal Criteria Formulas for the Exponential versions, you may want to try the following approximations:
EMA2 of Force Index:
((C - C1) * V + 1 / 3 * ((C1 - C2) * V1 + 1 / 3 * ((C2 - C3) * V2 + 1 / 3 * ((C3 - C4) * V3 + 1 / 3 * ((C4 - C5) * V4 + 1 / 3 * ((C5 - C6) * V5)))))) / (3 / 2 - 1 / 2 * (1 / 3) ^ 5)
EMA13 of Force Index:
((C - C1) * V + 12 / 14 * ((C1 - C2) * V1 + 12 / 14 * ((C2 - C3) * V2 + 12 / 14 * ((C3 - C4) * V3 + 12 / 14 * ((C4 - C5) * V4 + 12 / 14 * ((C5 - C6) * V5 + 12 / 14 * ((C6 - C7) * V6 + 12 / 14 * ((C7 - C8) * V7 + 12 / 14 * ((C8 - C9) * V8 + 12 / 14 * ((C9 - C10) * V9 + 12 / 14 * ((C10 - C11) * V10 + 12 / 14 * ((C11 - C12) * V11 + 12 / 14 * ((C12 - C13) * V12 + 12 / 14 * ((C13 - C14) * V13 + 12 / 14 * ((C14 - C15) * V14 + 12 / 14 * ((C15 - C16) * V15 + 12 / 14 * ((C16 - C17) * V16 + 12 / 14 * ((C17 - C18) * V17 + 12 / 14 * ((C18 - C19) * V18 + 12 / 14 * ((C19 - C20) * V19 + 12 / 14 * ((C20 - C21) * V20 + 12 / 14 * ((C21 - C22) * V21 + 12 / 14 * ((C22 - C23) * V22 + 12 / 14 * ((C23 - C24) * V23 + 12 / 14 * ((C24 - C25) * V24 + 12 / 14 * ((C25 - C26) * V25 + 12 / 14 * ((C26 - C27) * V26 + 12 / 14 * ((C27 - C28) * V27 + 12 / 14 * ((C28 - C29) * V28 + 12 / 14 * ((C29 - C30) * V29 + 12 / 14 * ((C30 - C31) * V30 + 12 / 14 * ((C31 - C32) * V31 + 12 / 14 * ((C32 - C33) * V32 + 12 / 14 * ((C33 - C34) * V33 + 12 / 14 * ((C34 - C) * V34 + 12 / 14 * ((C35 - C) * V35 + 12 / 14 * ((C36 - C) * V36 + 12 / 14 * ((C37 - C) * V37 + 12 / 14 * ((C38 - C) * V38 + 12 / 14 * ((C39 - C) * V39 + 12 / 14 * ((C40 - C) * V40 + 12 / 14 * ((C41 - C) * V41 + 12 / 14 * ((C42 - C) * V42 + 12 / 14 * ((C43 - C) * V43 + 12 / 14 * ((C44 - C) * V44))))))))))))))))))))))))))))))))))))))))))))) / (7 - 12 / 2 * (12 / 14) ^ 44)
