Please try the following:
Select Chart Template | Add Indicator | Indicator.
- Center Zero Line: Checked
- Plot using price scale: Unchecked
- Smoothing Average: 1
- Average Type: Simple or Exponential (Doesn't matter because the Smoothing Average is 1).
- Indicator Formula: 100 * (C - C1) * V
This will return the raw Force Index. If you wish to smooth the indicator, adjust the Smoothing Average and Average Type as appropriate. You may wish to review the following:

pzirakian,
Your formula is for the Cumulative Force Index. It is plotted by constructing a Custom Cumulative Indicator with:
Up Condition:
ABS(V)>=0.0
Down Condition:
ABS(V)<0.0
Value To Add/Subtract:
V*(C-C1)
Thanks,
Jim Murphy

Is there a way to name an added indicator? When it appears on the screen the formula appears, this could get cumbersome if the formula is long. Naming it would be handy for immediate recognition from screen to screen as well.

TeoDowning,
It is possible to start the formula with the "name". You can even put the "name" on the first line and have the formula on the second line (although this requires writing the formula in another program and pasting it into the formula window).
This is not supported however (meaning it could stop working at any time) and great care must be taken in constructing the name. If it contains reserved symbols or words, TeleChart will see it as a formula and attempt to evaluate the name. This will normally result in an error of some sort, but could result in a mis-calculation instead.
