The center line is an exponential moving average ; the price channels are the standard deviations of the stock being studied. The bands will expand and contract as the price action of an issue becomes volatile expansion or becomes bound into a tight trading pattern contraction. Learn about the difference between simple and exponential moving averages by checking out Moving Averages: A stock may trade for long periods in a trend , albeit with some volatility from time to time.

To better see the trend, traders use the moving average to filter the price action. This way, traders can gather important information about how the market is trading. For example, after a sharp rise or fall in the trend, the market may consolidate , trading in a narrow fashion and criss-crossing above and below the moving average.

The standard deviation is then multiplied by a factor typically 2. We calculate the upper band by adding the standard deviation multiplied by the factor to the moving average. We calculate the lower band by subtracting the standard deviation multiplied by the factor from the moving average.

This means that you can apply them to any market and timeframe without needing to adjust the parameters. You can learn how to backtest your trading strategies using a Tradinformed Backtest Model. The models are built using Excel and you can use them to test on any timeframe and market.
