Text: the authors confirm that, for approved reasons, some access restrictions apply to the data underlying the findings. the trading data analyzed in the work was not directly collected by the authors, but provided by an online trading company, according to their data privacy policy and their agreement with mit. hence, due to both ethical and legal concerns, the authors cannot make the data public available without the permission of the company. however, upon request, they can refer any researchers to that company, which provides access to past data (and specifically  the same data that was used for this research) through their platform to academic researchers who sign an agreement with them (which is what the authors did). hence it is totally possible for other researchers to reach the data owner by contacting yanival@media.mit.edu.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
