Calculates the Envelopes indicator on data, stored in array, and returns its value

Parameters

array	Array with data
total	The number of items to be counted. 0 means the whole array
ma_period	Averaging period for calculation of the main line
ma_method	Moving Average method. It can be any of following values: MODE_SMA Simple averaging MODE_EMA Exponential averaging MODE_SMMA Smoothed averaging MODE_LWMA Linear-weighted averaging
ma_shift	MA shift. Indicator line offset relate to the chart by timeframe
deviation	Percent deviation from the main line
mode	Indicator line index. It can be any of Indicators line identifiers value (0 - MODE_MAIN, 1 - MODE_UPPER, 2 - MODE_LOWER)
shift	Index of the value taken from the indicator buffer (shift relative to the current bar the given amount of periods ago)

Returns

Numerical value of the Envelopes indicator, calculated on data, stored in array[]
