The data stored here come from a lab-in-the-field experiment, called Mr. Banks, where volunteers are given a controlled set of financial information -based on real data from worldwide financial indices- and they are required to guess whether the market price would go up or down in each situation. Data is used to explore basic statistical traits, behavioural biases and emerging strategies. More details can be found in the following publication: Mario Gutiérrez-Roig, Carlota Segura, Jordi Duch and Josep Perelló.
