Never believe trading signals, they are just scams.
If anyone has the correct trading signals he has become a millionaire, and he only needs to think about how to spend his money instead of selling those trading signals.
Quite interesting, why do we have mentors and teacher all over the whole, that's because they want to pay the knowledge to the next generation. Are there signals providers that are honest and quite profitable to follow? Yes but you'll be doing yourself less good and more harm. There's nothing specific in waiting on someone else to interpret the market and make you money.
Doing so will only make you lazy, you can learn this skills within months although to perfect them, you'll need experience which can only be gotten from continues practice (time). That been said, you have to make yo your mind to acquire the skills involves in trading if you want to become a professional traders.
Bits invite other hand ar quite understandable, you are basically inputting your knowledge into the bot and it excute thai tasks automatically but if you're speaking of bots that trades for you with their own interpretations then that's as wasteful as relying on signal providers.
