Smoothing Methods

Many technical indicators are based on various methods of the price series smoothing. Some standard technical indicators (iAlligator(), iEnvelopes(), iEnvelopesOnArray(), iForce(), iGator(), iMA(), iMAOnArray(), iStdDev(), iStdDevOnArray() and iStochastic() indicators) require specification of the smoothing type as an input parameter. For specifying the desired type of smoothing, identifiers listed in the ENUM_MA_METHOD enumeration are used.
