Parameters

Name	Type	Description
Length	Numeric	Sets the number of bars to consider for the directional movement index minus calculation.

Remarks

DMIMinus measures downward movement strength.

DMIMinus is the one of the core components to the directional movement calculations. It is derived by comparing the Low of the current bar to the Low of the previous bar. If the Low of the current bar is less than the Low of the previous bar, than DMIMinus value is that difference for the current bar.

The DirMovement function calculates the DMIMinus value.

The value for the Length input parameter should always be a whole number.

Example

Assigns to Value1 the DMIMinus value where the DMI length is 14 bars, then plots Value1:

Value1 = DMIMinus(14);

Plot1(Value1, "DMIMinus");
