I am a beginner, I still don't know how to operate to leverage the bankroll, so for now I put in 4 $ just to learn how to trade

I started investing a while ago, on the recommendation of a friend. I confess that I don't have the necessary wisdom to invest like this, but I started with 950 reais. Currently, it's like this. Can you give me tips on how to redistribute this amount to leverage more and at least match the initial amount?
