midpoint() – EFS

midpoint() Series Functions

The midpoint() function is used to create a Series Object of the midpoint value found in a series within a specified number of bars. It is implemented as ( highest value found + lowest value found ) divided by 2.

Syntax

midpoint( nLength [, Series | sym() | inv() ][, nBarIndex ] )

Parameters

Parameter:	Description:	Default:
nLength	Required. Number of periods to use for calculation.	n/a
Series or sym() or inv()	[Optional] Series Object or function of sym() or inv() to determine symbol/interval source for the study.	Chart's sym/inv
nBarIndex	[Optional] Bar index of series to retrieve . See Notes.	n/a

Return Value(s)

Returns a Series Object when nBarIndex is not specified.

Returns a single value when nBarIndex is specified.

Notes

The nBarIndex parameter is available only starting with version 10.5

Code Examples

function main(){
	//create a Series Object of the midpoint close price. 	
	var xSeries =  midpoint(10);
	//create a Series Object of the midpoint low price. 
	var xSeries =  midpoint(10, low());
	//create a Series Object of the midpoint low price of IBM. 
	var xSeries =  midpoint(10, low(sym("IBM")));
	//create a Series Object of the midpoint low price from 15 min interval. 
	var xSeries =  midpoint(10, low(inv(15)));
	//create a Series Object of the midpoint value from sma(20). 
	var xSeries =  midpoint(10, sma(20));
	//retrieve a single value for the current bar. 
	var nValue_0 =  midpoint(10, 0);
	//retrieve a single value for the previous bar. 
	var nValue_1 =  midpoint(10, -1);
