Description

The Double Exponential Moving Average (DEMA) is a combination of a single exponential moving average and a double exponential moving average. The advantage is that gives a reduced amount of lag time than either of the two separate moving averages alone.

Syntax

DEMA(int period)
DEMA(ISeries<double> input, int period)

Returns default value
DEMA(int period)[int barsAgo]
DEMA(ISeries<double> input, int period)[int barsAgo]

Return Value

double; Accessing this method via an index value [int barsAgo] returns the indicator value of the referenced bar.

Parameters

input	Indicator source data (?)
period	Number of bars used in the calculation

Examples


// Prints the current value of a 20 period DEMA using default price type double value = DEMA(20)[0]; Print("The current DEMA value is " + value.ToString()); // Prints the current value of a 20 period DEMA using high price type double value = DEMA(High, 20)[0]; Print("The current DEMA value is " + value.ToString());
