How to Plot Custom SCID File Data on Chart?

Hello,

I have a custom ACSIL study (computationaly heavy) that calculates values and writes them to an SCID file using sc.RelayTradeUpdate(). The SCID file is being created and contains data.

Problem: The chart shows no bars/values. The SCID file exists with data, but I cannot get Sierra Chart to display it.

What I need: A way to open/display an existing SCID file as a chart - without recalculating all the historical values again.

Questions:

What symbol/chart settings are required to display data from a custom SCID file?
Is sc.RelayTradeUpdate() the correct function for this use case, or should I use something else?
Do I need to configure the symbol as "No Data Feed" in Global Symbol Settings?
The data is already computed and saved - I just need Sierra Chart to read and display it.

Thank you,
user396
