Online share trading is no longer restricted to expert brokers; there is a diverse population of traders with varying abilities and experience. Decision making in this context can be sub-optimal and risky. This study investigates how performance varies with level of cognitive ability and speed of online trading, and whether a decision aid can overcome traders’ disadvantages. The study showed that novice traders with decision support consistently outperformed those without and that the decision aid mitigated the negative effects of higher decision-making speeds and lower cognitive ability. This adds to decision making under time pressure and behavioural finance literature.
