The classic EMA with the linear combination of price timeseries. The formula for the calculation:
NavelEMA = EMA( ( close*5 + open*2 + high + low ) / 9 )
This indicator was first implemented in MQL4 and published in Code Base on 05.02.2009.
The indicator uses SmoothAlgorithms.mqh library classes (must be copied to the terminal_data_folder\MQL5\Include). The use of the classes was thoroughly described in the article "Averaging Price Series for Intermediate Calculations Without Using Additional Buffers".
