A trader also needs to control his emotions. Moreover, this control should be in place both in successful transactions and in unsuccessful ones. After all, it often happens that when a trader begins to succeed in something in trading, he is overcome by euphoria and self-confidence, which pushes the trader to overestimate the risks in transactions in order to earn even more, which ultimately leads to the loss of the entire deposit. In case of unsuccessful transactions, many people want to immediately compensate for losses, without waiting for strategy signals, and the lot of transactions increases to quickly compensate for losses, which also ultimately leads to even greater losses. Therefore, without controlling emotions in trading there will be no profitability.
