BB MACD is a MACD (Moving Average Convergence Divergence) indicator variation with an addition of Bollinger Bands, which helps in detecting trend change points and measuring current trend's strength.

The indicator is separated into three parts:

• The "line" part which is the colored MACD value.
• The "channel" part which is the Bollinger Bands drawn that way to make it easier to spot the changes of MACD within the channel.
• The "early levels" part which is the Bollinger Bands using smaller deviations multiplication for early assessment of MACD trend change.
