Even if you're to make use of the technical and fundamental analysis we have in trading or tracking the market price, you will still need to do your own research, this will help you to know what more better and apply the right method to use, we also have to understand that either we make use of the random signals or the technical fundamental analysis as the case may be, we have to either be on the winning or losing as we cannot afford to always be accurate or inaccurate about the signal used.
When we do fundamental analysis or technical analysis that is a part of doing our own research and that is the best way to trade with more confidence. Doing everything yourself is better than depending on others, there are some things that you'll need help through collaboration or learning directly from others but don't depend totally on them or you'll be going down a path that wouldn't be good for you as you trade for a longer time.
Random signals can cause you to lose as you don't know if the signals are good ones or bad ones. There are alot of fakers online and they can post fake signals just to make it look like they're good at providing signals draw attention of newbie that they're want to scam and if you don't do your own research but depend on them, you're going to lose.
