Custom Spread Symbol Creation

Hello SC Support Team,

I am attempting to create a custom symbol displaying the spread between the SPX cash market and the current ES futures contract. I have subscribed and agreed to the CBOE data to receive the SPX_CGI symbol real-time. I have also done the same with the CME futures through Denali feed to receive real-time futures data for ESZ25_FUT_CME. I believe DTN IQ Feed does have a symbol that shows this but I am trying to replicate it with my current data subscriptions. I have been trying to follow the instructions on Custom Calculated Symbols but I get a blank chart in the end.

I have attached a picture of my current symbol settings and a picture of the IQ symbol description of what I am trying to replicate. Essentially the difference between the cash market and the futures. Please let me know what other information you need or how I can achieve my desired result.

Thank you.

Please get us an image of the chart by following these instructions:

We know it seems odd to ask for a blank chart, but there are some items that we can get information from.
