Stock Trading Robot Makes Decisions Based on Superstitious Algorithms

• Colin Lecher via

When we feel there's a situation out of our control, we often fall back on superstition to account for it. ("Nothing else is working, why not blame it on that black cat?") But when enough of us rely on superstition, it's not just an individual comfort; it starts to have real repercussions. Now a designer has created an algorithm trades stock superstitiously, and it's going to see if gambling based on full moons and thirteens can pay off.

Sid the Superstitious Robot (for which you can see the open-sourced code if you're so inclined) is governed by a set of rules programmed by 25-year-old Shing Tat Chung. Among them are a phobia of the number thirteen that prevents it from trading stocks on the thirteenth day of the month. On the other side of the scale, it has an affinity for new moons, but will sell during a full moon. It's a rewiring of other trading systems that make decisions based on more rational changes, such as costs of certain goods or other expected outcomes.

But those beliefs aren't concretely set; Sid incorporates new ones based on feedback from his performance. That doesn't equate to rationality: a certain pattern can be observed but also be imaginary, and the algorithm will incorporate it based on a superstitious "feeling" that it evokes.
