Just doing analysis for practice

Hi, I'm a newbie and honestly I don't know much about financial markets, but I'm a person who likes to observe, create and invent.
I don't like those already-made strategies because I don't understand them well, so I'm trying to test if the strategy i am creating and I want to use works.
I think the best way is to try and test it here on tradingview, so don't take my ideas as trading tips or investing tips.
I'm just a newbie
