Trading in financial markets is associated with a high failure rate, which the research literature traces to psychological factors and lack of trading discipline rather than technical knowledge. While technological solutions (FinTech) have been proposed as a tool to reduce human errors, their empirical impact on the psychological dimensions of traders has been less measured. The main objective of this study was to quantitatively and statistically examine this relationship. This study used a descriptive-correlation method to assess the role of FinTech tools in improving emotional control and trading discipline. Data were collected using a questionnaire from a sample of 100 traders active in the Forex and digital currency markets. The results of the structural equation modeling (SEM) analysis showed that the use of FinTech tools has a positive and significant relationship with increased emotional control and improved trading discipline. These findings provide empirical evidence that fintech can act as an external “behavioral anchor” to help traders stick to their strategies by structuring the decision-making process and providing objective feedback, provided that it is used on the basis of a valid trading strategy. The innovation of this research lies in providing quantitative evidence for the link between behavioral finance theoretical foundations and technological solutions, filling an existing research gap by testing an empirical model.
