You can use this indicators in different ways

• Moving Average
• Range area
• Filtered area of market movement

You can set :

• Average period of candle=HeikinPeriod
• Average Type (simple,exponential,triangular, etc) = AverageType
• Average period of impression channel (Highest/Lowest) = ChannelPeriod
• Transparency of the candle =Transparency
