Looking at the backtest report, thinking "What if" or "if only"

At face value, the figures look great in your backtest report but the story it tells is minimal. Forget about being a multi-millionaire as per the report (that wouldn't have happened) but concentrate on using the report to find improvements hidden within the parameters that you have used. Using a Bollinger Band Breakout Strategy profitably is dependent on the deviations of both bands, the lookback period within the periodicity that you elect to use. 


There are a few suggestions 

1. I would prefer to see a backtest for the calendar year for 2011- that is my first benchmark with system development.

2. I would also like to look at the Monte Carlo report & concentrate on the Annual Return report. (now that tells a powerful story)


Bollinger Band "Background" for others

Bollinger Bands a technical indicator developed by John Bollinger. The indicator forms a channel around the price movement. The channels are based on standard deviations & a moving average. Bollinger bands can help you establish a trend's direction, spot potential reversals & importantly monitor volatility. All of this can help you make better trading decisions if you follow a few simple guidelines.


The Basics

Bollinger bands have three lines, upper, middle & lower. The middle line is a moving average of prices. There is "no magic moving average number", so it's important that the moving average (the middle line) aligns with the techniques & strategy being traded. The upper and lower bands are drawn on either side of the moving average. The distance between the upper and lower band is determined by standard deviations. (these parameters & "others" are critical to the profitability of the strategy)
