My advice for beginners is to make it a habit to learn from the beginning because if you directly use signals from other people then you will never know how you can enter and exit, but if you mean signals from indicators such as oscialtor or bolinger band, you can just learn one , for example you use stochastic, then you just have to wait for the order in the area of 80 to be overbought and get ready to sell and vice versa if in the area of 20 oversold, get ready to buy, so my advice is to study independently don't rely on other people's signals
