Research: Best ways to identify a Buy/Sell

Hello everybody,

I am interested in the intersection of trading and computer science and I would prerequire that there is a way to "predict" good situations to go long or short on a certain stock or crypto.
That being said, I am interested what the best indicators, signals, media hype, ect are to make the prediction as good as possible.

• is it candle patterns? if yes, which ones are the most promising you think?
• what indicators would you recommend?
• what are the most important timeframes? 1m 1h 4h?
• media sentiment
• fundamental KPIs
• what ever you think would be beneficial in addition

I am trying to compound all these signals to be in the end able to create an app that can help supporting this selection.

What do you think? Happy for your inputs
