Statistics for Traders
Statistics is one of the most misunderstood and abused subject in mathematics (and science). The reason is something we can all easily understand – statistics is something we can all sort of relating to but counter-intuitive when applied in event by event situations.
Our brains are wired that way so that our ancestors can survive in nature. Since human has not evolved into any better forms for quite some time, yet our civilization is advancing in such a pace that even our computers are outdated every year or two, our minds are not that cooperative when it comes to making decisions that are drastically different from the ones that our ancestors faced. The ability to adapt our minds in making proper trading decisions boils down to our ability in applying logical thinking and statistical analysis properly.
It all sounds so complicated but in reality all you have to do is to take time understanding some basic concepts in statistics, then utilize the distilled rules and concepts to make better trading decisions, as oppose to relying on our gut feelings.
