Keep calm, and have a coffee, said me a trader when lemhan and half financial world collapsed in 2008. He said "Don't follow your ideas, follow the market! Remember that as the world goes, there will always be something to eat ".
Nothing could be more true!
If you are a trader, a real trader, you will make your fortune when the market goes down and others sell! Short all & buy at discount. The sales time is starting
To keep calm is ability which is needed to succeed in any situation in life as well in trading.
Indeed keep calm and everything will be okay sooner or later
