If you're a beginning trader, I can recommend you to try out everything.
Different trading styles, indicators, patterns, you name it. Try out everything and see what works for you.
Only then you can start evaluating and see what you are good at and what fits you as a person.
When you are experimenting, I would recommend to keep your risk to a minimum. You are practicing after all. I do favor using your own money vs a demo account though as you will make different decisions if you are trading actual money.
