Two lines are channel averages created by High and Low price values for different periods displayed as clouds. Two indicator buffers and two indicator lines are added into the 2MoHLC_ indicator for a visual drawing of the indicator.
This indicator was first implemented in MQL4 and published in CodeBase on mql4.com on 24.06.2010.
