Fear, anger, anxiety, despair, rage, euphoria, self-confidence, control over the market, etc.... They will destroy your deposit. Beginner traders primarily study trading techniques and miss an important factor in the market - this is “psychology” and personal emotions.
A biased assessment of this aspect in trading is “expensive.” Many people go a very long way to psychological and financial stability.
Don't let emotions get into your trading! Always follow your rules, strategy. Complementing with patience and measure! Emotional discipline is the path to success.
An exchange is not a casino where you can make quick money.
