in trading need a lot of insight. This is important because of course it is not easy to falter with the establishment. It is often easy for affected merchants to be afraid of the situation there and eventually make them unable to evolve and get satisfying results.
Do you try to say that trader must be clairvoyant? As I learn different technical analyses theories all they tell that market state have all future events in itself already. It mean that any event is reflected in the graphs already without publications. And enough to follow to price chart.
