Fixing obsolete cTrader, cAlgo C# Csharp code 2023, Chart Objects

Hello Every1

I am very new to coding and started updating old code on my self, well I am trying..

I would like some help on how to fix obsolete code in VS 2022, the correct way, step by step. where to find in which register, how to read the code, how to transfer, translate old definitions to new ones.

Please use the code underneath as an example, and please only links and vids from 2023, anything older is the past ;)

Thank you for any help
