STAT
System Description
SPC Finally Comes To Trading Systems
The worldwide productivity increase has in large part been due to controlling
processes through the use of Statistical Process Control (SPC). Now, for the
first time, there is a commodity trading system that uses this technique to
extract profits from the commodity markets.
The reason many systems that use a similar approach have problems is because
they assume commodity prices are "normal". They try to take advantage
of the probability characteristics of a normal distribution. They think they
will be successful because prices fit a bell shaped curve or normal frequency
distribution. The way these systems usually operate is by using a moving average
crossover approach. They also usually tack on a couple of standard deviation
bollinger bands to try to keep from taking too many false trades.
Bad News! Commodity prices do not form a normal distribution. In many
cases the distribution isn’t even close to normal.
Good News! STAT doesn’t care. It uses special techniques to
generate a normal probability distribution out of prices. Then STAT uses the
well developed SPC concept to take its trades. So STAT comes much closer to
being technically correct than most of the other moving average crossover
systems.
