Not really a good idea if you do really rely with others signals but always verify it for yourself if those analysis were considerable or totally just a trash.
Without knowledge and experience then you cant really determine which one is good and which one is bad. You can make use of others analysis
but doesnt mean that you would simply rely into those and to think that fails and mistakes do commonly happen because
this had been part of the learning process. You wont learn if you wont commit mistakes but as you earn experience you would surely improve.
That's why I said that joining a trading signal group isn't worth the time to waste on them. I don't fully agree with you saying that you won't learn if you don't make mistakes because the wiser way is to learn from the mistake of the other people.
