Trading signals are mostly scams but not all, the ones selling them only makes their profits from the stipends you pay for or subscribe to. It's none and void, I don't follow signals, I create my own signals with the market charts either from technical or Fundamental analysis, but I based fully on technical analysis. Trading signals are mostly hinted for newbies in the market because they understand nothing and trading for the first time triggered fear especially when the trade is not going according to plans. We should be able to analyze the market by ourselves rather than depends on false signals that's totally wrong with the market, giving more room to losses.
To be honest, I have joined several signal groups, after several months of following the group's signals it turns out that my loss level has increased, after I reset, it turns out that most groups only seek profit from members, and cannot contribute to their members. In addition, now I realize that everyone's trading style is different, everyone has different technical and fundamental analysis.
So now I prefer to practice my own strategy rather than relying on other people, because this has proven to be more effective even though I experienced a loss, but at least this can be a learning material not to repeat it and be a little more advanced. Create your own strategy.
