Thinking about how trading strategies need to always be changed and how one strategy may not work for a long time, what do you do with the strategy that you are about to change. do you just forget about it completely once a new strategy starts working for you? or do you keep it in remembrance for the future. If you have experienced this before; has any old trading strategy that you decided to apply work for you? Is it possible that old strategies may work in the future again?
If you know a thing or two about programming or coding, you should know that there are a lot of programming languages, and almost all of them are used for different purposes and has different use cases and powers of their own, but, almost all of them have some similarities among them.
So even if a new programming language is developed, having knowledge of a previous language helps you learn it more quickly or maybe sometimes use things from the old one in the new one. Similarly in trading, an old strategy should always stay with you, even if there is a new strategy that you develop yourself or just adapt, your old strategy will still be able to assist you at times.
