It is important not to succumb to panic, and when panic arises, I recommend leaving the market and waiting for the market to change. A new U.S. credit rating recalculation was announced, and according to forecasts, the news will be negative and the dollar will fall.

Traders attempted to get out of the currency, which contributed to the panic and pushed the trend lower.
It turned out the ratings didn't change, the trend was reversing, and the guy who didn't cause trouble won. You never know ahead of time if a crash will happen on a stock exchange.
