Williams %R is just the raw Stochastic minus one hundred (it runs from -100 to 0 instead of 0 to 100). So to create a Custom Indicator for a 10-Period Williams %R:

Select Chart Template | Add Indicator | Indicator.
- Visible: Checked
- Center Zero Line: Unchceked
- Plot using price scale: Unchecked
- Smoothing Average: 1
- Average Type: Doesn't matter (because the Smoothing Average is 1)
- Indicator Formula: STOC10 - 100

Another option might be to just add the built in Stochastic indicator and adjust it mentally. The Stochastic will run from 0 to 100 while the Williams %R will be autoscaled (although this may not matter with a short enough Period vs Zoom). You may wish to review the following:
