A cautionary tale about the dangers of facile backtesting... I think.
Rattraders is an experiment in which I trained lab rats to trade in the foreign-exchange and commodity-futures markets. With the help of these rodents, I managed to outperform some of the world's leading human fund managers. My motivation was to find out what kind of highly paid jobs will eventually be replaced by machines—or, as was the case here, by rats. Like the work of many in this field, my research indicates that all jobs that do not require human-to-human interaction may be replaceable. I focused on brokers because of their high earnings, but the job itself seems to be based on pattern-recognition capabilities and the ability to avoid distractions. I figured that rats might be up to the task.
