getValueAbsolute() – EFS

getValueAbsolute()

Returns the value of the specified type at the specified bar index relative to bar 0, regardless of the bar currently being processed.

Syntax

getValueAbsolute( barType [, barIndex ][, numBars ][, Symbol ] )

Parameters

Parameter:

Description:

Default:

barType	Required. String for type of value to retrieve: "open", "high", "low", "close", "time", "rawtime", "volume", "oi", "year", "month", "day", "hour", "minute", "second"	n/a
barIndex	[Optional] The number for the bar index (or beginning index) to retrieve.	0
numBars	[Optional] Total number of bars of data to retrieve.	1
Symbol	[Optional] String specifying a symbol to use, which may also include an interval (e.g., "IBM,5").	chart symbol

Return Value(s)

Returns a single value if numBars is not specified or is 1.

Returns an array of values if numBars is specified and greater than 1.

Notes

Using getValueAbsolute( "time" ) can be very processor-intensive and, for that reason, its use is not recommended. Instead you should use getValueAbsolute( "rawtime" ) which returns the number of seconds elapsed since 1/1/1970.

Code Examples

function main(){ 
//retrieve the close from bar -10 
	var myVar = getValueAbsolute("close", -10);	 	
//retrieve the rawtime of bar 0 
	var myVar = getValueAbsolute("rawtime", 0); 	
//retrieve 20 high values into an array starting at bar 0 
//where the [0] element of myArray contains the high at bar 0.	
        var myArray = getValueAbsolute("high", 0, -20);	
// more common method	
//retrieve 20 high values into an array starting at bar -19
//where the [0] element of myArray contains the high at bar -19.	
        var myArray = getValueAbsolute("high", -19, 20);
// less common method
}
