Step 3: UN-CHECK the Fit Studies check box.
Step 4: Make sure Scale is set to Auto.

You can also get to these settings by clicking the Price Axis Settings icon in the top right corner of your TOS chart (see above).

How to scale an indicator in TOS:

If you notice that the charts on your screen in TOS are squished, scrunched, or tiny and hard to read, chances are you will need to make one quick adjustment to fix this visibility issue. 

Most of the time, this will affect your Voodoo Lines, Lay Up Indicators, or any indicator that displays significantly above or below the area for the price. 

Please be sure your indicator is applied to the chart so you can note the difference once the changes have been made.

Next, on the top menu in Thinkorswim, select Style > Settings > Price Axis
This will bring you to the menu where you can set the scale setting.  

From here, you will need to make sure and set the “Scale:” to Auto, then
UNCHECK the box for fit studies.

Click “OK,” and you should be all set.
