Take a look at tradingview.com! It's an amazing (free!) tool for charting and the Bitcoin chat community is quite active, knowledgable and helpful! Just keep in mind that it isn't obvious easily who's right or wrong, and that even the best chartist/trader does make wrong predictions regularly, so don't follow anyone blindly

As someone else said, it isn't so much about being right or wrong, but about improving your odds, finding critical points where something is bound to happen, and finally managing your trades in a way that you profit in the end.
