updated! added the link to the original Savage indicator
added explanation of how to overlay studies!
Sadly, no. You cannot edit the ToS indicators directly.
They are stored on the Schwab servers. Obviously, they wouldn't want traders coming along and mucking them up.
The most common method of editing indicators is:
1. double-click on the indicator.
2. color in and copy the entire indicator
3. click on the create button
4. paste the entire indicator
5. save with a name that you will remember.
After that, you can edit it as much as you want.
You can add a mid-line by appending this code snippet to the end of the code:
You can customize it with multiple stochastic lines, similar to this one that is popular with the members:

Or as you stated, you can copy the StochasticFast into a separate new study.
And then overlay it, multiple times, into the same lower chart.
You can modify each one, with the settings that you want.
Important:
1. you must first copy it into a new study as described above.
2. you MUST ADD the following code line:
declare real_size;
This ensures that all indicators, overlaid in a lower study, are drawn at the actual scale.
Otherwise, overlaid studies get hideous, do not behave, and do not provide reliable data.
NEVER! skip this step, if overlaying multiple studies into the same lower chart!
If you have overlaid indicators, incorrectly. You will know immediately.
Instead of numbers on the right-axis. There will be percentages.
This is ToS is informing you that the lower chart has mistakes.
Appending this code snippet into your studies will fix these errors.
declare real_size;
ThinkOrSwim has a steep learning curve; but each thing that you learn; can then be applied throughout the platform; so just keep asking questions.
If you have a question, probably so do many of the thousand viewers of the forum.
We all learn from the questions posted here!
