Randomness is unstructured freedom without responsibility. When we trade without well-defined plans and with an unlimited set of variables, it’s very easy to take credit for the trades that turn out to our liking (because there was “some” method present). At the same time, it’s very easy to avoid taking responsibility for the trades that didn’t turn out the way we wanted (because there’s always some variable we didn’t know about and therefore couldn’t take into consideration beforehand).
