Wealth lab. C# how to write a spherical function?

Question

C++ / C#

I am learning, I am writing a simple trading robot in wealth-lab on sharp.
It is required to write a spherical function that takes indicator data (bollinger lines in this case), takes the value of bars, calculates something, guesses on coffee grounds and gives the result. I can't describe it properly. Code and error below, spherical function - some_funct()

Answer 1

Would you like to create BBUp and BBMed arrays? If you create, then show the creation code, and where it is called.

Answer 2

In Wealth Lab, you can work directly with the DataSeries object. All bar values ​​are just such objects. Therefore, in order to allow you to calculate some values ​​based on the indicator data and bars, you can write something like:
DataSeries bband = BBandUpper.Series(Close, 25, 1);
DataSeries someValue = bband - Close;
Here we will get a new DataSeries object where the values ​​will equal the boileringer minus the closing prices.
