ADX (Function)
The ADX series function returns the average directional movement index (DMI) for a security.
Syntax
ADX(Length)
Returns (Double)
A positive numeric value for the current bar.
Parameters
Name | Type | Description |
Length | Numeric | Sets the number of bars to consider for the average directional movement index calculation. |
Remarks
ADX attempts to measure the trending quality of a security independent of direction. The greater the ADX value, the stronger a security is trending.
The DirMovement function calculates the DMI and ADX values.
The value for the Length input parameter should always be a whole number.
Example
Assigns the ADX value to Value1, where the ADX length is 14 bars, then plots Value1:
Value1 = ADX(14);
Plot1(Value1, "ADX");
