The existing literature on emotion regulation strategies provides important insights with regards to intrapersonal strategies for emotion regulation. However, in pointing out the limitations of intrapersonal emotion regulation models, it has been suggested that emotion regulation is not confined to intrapersonal processes and the complex social networks that humans form are intricately connected to their emotions. The previous work on financial traders has recognized the relevance of emotions in trading, focusing only on intrapersonal emotion regulation strategies. In this chapter, drawing on the author's previous research on emotions in trading as well as existing research on social sharing of emotions and interpersonal emotion regulation, interpersonal emotion regulation strategies in the work of financial traders are identified. In doing so, an existing definition of interpersonal emotion regulation is extended and it is argued that while the pursuit of a regulatory goal is paramount, the benefits of interpersonal regulation may be achieved even in the absence of live social interaction, as long as labeling of the affective state takes place. The chapter concludes with a model summarizing intra-interpersonal emotion regulation processes.
