Stocks & Commodities V. 24:3 (46-52): Trading Trends With The Bollinger Bands Z-Test by Jacinta Chan
Standard deviation bands are helpful in determining trends. Here, the author develops a trading system based on this idea that yields high returns with low, controlled risk.
The set of trading techniques that I will present here uses standard deviation bands to determine trends and help develop a trading system that yields high returns at low, controlled risk. The name for this trading system, BBZ, is an acronym derived from “Bollinger Bands” and the "z-score,” based on a Working Money article published in October 2002 by Veronique Valcu. In “Z-Score Indicator,” Valcu related z-scores to Bollinger Bands. Intrigued by the article and to continue that discussion, I wanted to take a closer look at that relationship and introduce the Bollinger Bands z-test (BBZ).
RECAP
The z-score (Z) measures the difference (direction) between the closing price (C) from the mean (n-period moving average) given the n-period standard deviation(s). Positive or negative values show that the closing price (C) is above (C>µ) or below (C<µ) the mean, respectively.
The properties that interest traders are return and risk. In finance, average depicts expected return and standard deviation depicts expected risk. In statistics, we can define range trading as prices that are observed within the expected one (1) standard deviation band. We define trend trading as prices that are observed above +1 standard deviation band (for uptrends) and below -1 standard deviation band (for downtrends).
This article will show how to design and develop this trading system. It outlines the research, why the z-score indicator is used, the tests, and the results.
