A lot of people hate charts because they do not predict anything and sometimes the chartist can come off more like a carnival sideshow barker than a serious market analyst. All those calls, warnings and targets… only to be wrong and have to revise, as if by magic.
But one thing charts can do is set very real parameters and rules. The new NFTRH key ETF chart service (added to the premium service at no extra charge) is purposely mechanical and rules based. It has been saying stock markets remain on bull signals and precious metals and commodities remain on bear signals. In a difficult market there is something to be said for rules.
