It depends on exactly what you want.

To start with, refer to the following and the item below it:
Chart Menu: Show Bid and Ask Lines (Chart menu)

And then there is the following study:
Bid & Ask Prices

If you want to get the actual spread itself as a single value, then you can use the Arithmetic studies to calculate the difference between the two subgraphs from the above study. Refer to the following:
Using the Basic Arithmetic Studies

You can then display the most recent value (or some offset value) using this study:
