EDUCATION: Bollinger Bands

Hello, dear subscribers!
The next topic of our education is the Bollinger Band channel.

What is Bollinger Bands?
BB channel consists of three lines: the moving average of close price, the MA plus/minus 2 standard deviations. This channel defines the most likely price swings range.

How to trade with BB?
There are two different situations for the BB trading.
The first one is the trading during the consolidation phase.
You should open the long positions when the price broke the lower BB and close when it reached the centraline. The short position you can open when the price hits the higher BB and close on the centraline.

The second situation is the trend trading. According to theory the periods with low volatility are preceded by the high volatility periond. When the the volatility is low the BB channel is squeezed and it is a good time to searching for the potential trend beginning. You can use Money Flow Index or other volume-based indicators for the trend confirmation. For example, when the price hits the higher BB and the money flow index value rapidly increased it can be the evidence of potential uptrend beginning.
The most difficult and important problem of the BB trading is the trend direction definition. If the trend is defined correctly this strategy becomes very profitable.
