It is hard to control emotion when it comes to money. The process of Panic selling occurs when a stock price rapidly declines on high volume. And we can't deny the fact that most of the newbies are doing panic selling and loss, some of the expert also feels uncomfort with the price movement because of the high volatility, but they can control thier emotion because they experience so many same hard situations before they become expert. So I suggest to continue learning and be more wise in the next trade for good.
