If you want to be a trader, avoid to used any platform. But, start learn to trade by your self with your own research and create your own strategi. if you are newbie, you can start to learn about trading phsycology, learn to make a profit from bear market. Following strategy from other it can be a big mistake, because no strategy on internet 100% true.
Why avoid using platforms if there are some which provide good foundations? i've come accross few sites which provided surprising good tools and indicators to use as guidelines while trading. DYOR is essential of course but it's much easier using platforms
Personally, I do not know of a single analytics platform which would not be mistaken in key moments.
Especially revealing are the events of the last few months when the behavior of Bitcoin was completely opposite compared to 100% of the predictions.
Third-party analytics = other people's mistakes.
