Double Bollinger Bands Trading System

This is a long only trading system that uses two Bollinger bands indicators with different look back periods.

Bollinger Bands is a technical analysis tool created by John Bollinger and it consists of two lines (upper and lower lines) that form an envelope around the price series or any other time series (in case Bollinger bands function is applied to another indicator).

Entry rules are defined as follows:

Buy when a stock is trading below the 14-bar and 60-bar lower Bollinger bands
Buy when the price is higher than $2 and the average trading volume is higher than $100,000

Exit rules are defined as follows:

Sell when a stock is trading above either the 14-bar or the 60-bar upper Bollinger band.
Sell when the stock decreases more than 70% from its highest high. This is implemented using a 70% trailing stop.

Strategy Settings:

The maximum number of positions is 10.

Optimization:

Several parameters can be optimized in this trading system:
- The lookback period of the first Bollinger bands
- The lookback period of the second Bollinger bands
- The trailing stop level
- The maximum number of positions in the portfolio
