What tools do you use while you trade?

By this I mean are you using coinmarketcap or something else? Do you draw those lines and functions in hope to predict the moment of prices? Or you are simply one of those news hunters and buy when there's good news and simply dump coin later? Do you look and read in depth about the coin or you simply buy it based on surface information because you know others are looking at the surfice?

Hope I will get good quality answers.

Don't spam pls if you don't have anything clever to say, thanks.
