Volatile financial environments such as the forex and cryptocurrency markets are complex arenas for decision-making under intense pressure. Sustained success in these markets depends not only on technical knowledge and market analysis, but also on the ability to effectively manage emotions and cognitive biases. The purpose of this study is to examine the impact of emotion control and financial decision-making power on the continued profitability of forex and cryptocurrency traders.The sample of the study consisted of 100 Iranian traders in these markets. Data were collected through researcher-made questionnaires on emotional control and financial decision-making, as well as actual profitability reports from the MetaTrader software, and hypotheses were tested and analyzed using structural equation modeling (SEM). The results showed that both emotional control and decision-making power have a positive and significant relationship with profitability, which emphasizes the underlying importance of psychological skills in achieving sustainable performance in financial markets.
