Trading tools might be helpful but I would never rely on them, not only ont them. I believe that trading tools can't replace your ability to make decision, your knowledge and experience, that data and analysis only are not enough. Some users think that trading tools will help them make better profit but to my opinion that is more question of luck and coincidence.
Anyway, use trading tools as assistance, not as your main tool in trading.
I'm convinced that those sources help do deep research and understand the market from different points of view. It doesn't mean you shouldn't have your own vision but using them is a good place to start or change your own considerations. There are plenty of author reports on what will be successful tomorrow, but giants know better what will win in the market.
