I think the problem with new traders focusing on a TA based approach is that they're ignoring the underlying behaviour that drives the patterns, putting the cart before the horse. When I started to think about the interaction between traders that results in the patterns I trade, the indicators became pretty useless.
rather than saying ''double top pattern - short'', say, ''buyers failed to make a new high - short''
So 'trading the behaviour' is just changing the language you use to describe where and why you are taking a trade and what you think is happening, but in the end gives the same entries and the same result since it's all visual and manifests itself as bars on a chart.
