Best way to precompute a custom formula and store it

I've been trying to think of a way to work around the memory issue that I've submitted that I've encountered when heavily using the
chande_trendscore_by_symbol. I was thinking the answer could be to precompute the values for each stock quote and store it.

What would be the best way to do that? Is there a way from the script editor to access custom functions? Ideally I'm thinking the best way to do this
would be to create a c# function that computes the value and have both a script that can sweep the database and update the precomputed values,
and enhance the downloader to compute these as the data comes in.

If I can't do that, is the only option I have to rewrite the chande_trendscore_by_symbol function to not use the cFunctions and be a standard function
that can be invoked everywhere?

Appreciate any guidance you may have.

Hi Stefan,

We have solved the memory problem. We will send you an email explaining the changes we have made.

You can access a custom function in the global script using the ParserTool class.
Example: ParserTool.CreateParser("a = customfunction()");
