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 getValue( "time" ) can be very processor-intensive and, for that reason, its use is not recommended. Instead you should use getValue( "rawtime" ) which returns the number of seconds elapsed since 1/1/1970, or the getYear(), getMonth(), getDay(), getHour(), getMinute(), getSecond() functions (see Series Functions).

Code Examples

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