Hi Samir,
well, I think trading is mainly dominated by human psyche.
Humans react on news (corporate, ECB/FED-decision, enviromental catastrophes, war and so on). Their reaction can be seen in the chart.
An example:
Fact: A company publishes its year earnings.
You say => Fine, they are better than I expected => you open longs.
I say => that profit was too less => I open shorts or close my longs.
What's your opinion?
Best regards
