The panic can be stopped only in one way, as I understand. This is the improving professionalism in the trading. For me, this means the respecting the rules of psychohygiene, the following chosen trading strategy (not changing it at the slightest blow), the forming rational attitudes, the controlling emotions, the studying trading and psychology. If each of us does this, the situation on the exchange will become much more favorable and stable. Perfect, is not? =)
