We study the relationships between the real-time psychophysiological activity of professional traders, their financial transactions, and market fluctuations. We collected multiple physiological signals such as heart rate, blood volume pulse, and electrodermal activity of 55 traders at a leading global financial institution during their normal working hours over a five-day period. Using their physiological measurements, we implemented a novel metric of trader's "psychophysiological activation" to capture affect such as excitement, stress and irritation. We find statistically significant relations between traders' psychophysiological activation levels and such as their financial transactions, market fluctuations, the type of financial products they traded, and their trading experience. We conducted post-measurement interviews with traders who participated in this study to obtain additional insights in the key factors driving their psychophysiological activation during financial risk processing. Our work illustrates that psychophysiological activation plays a prominent role in financial risk processing for professional traders.
我们研究了专业交易员的实时心理生理活动、他们的金融交易和市场波动之间的关系。我们在五天的时间里，从一家全球领先的金融机构的 55 名交易员的正常工作时间内收集了他们的多种生理信号，如心率、血流量脉冲和皮肤电活动。我们使用他们的生理测量数据，实现了一种新的交易员“心理生理激活”指标，以捕捉兴奋、压力和烦躁等情绪。我们发现交易员的心理生理激活水平与他们的金融交易、市场波动、他们交易的金融产品类型以及他们的交易经验之间存在统计学上显著的关系。我们对参与这项研究的交易员进行了测量后的访谈，以了解在金融风险处理过程中驱动他们心理生理激活的关键因素。我们的工作表明，心理生理激活在专业交易员的金融风险处理中起着重要作用。
