Smoothed Oscillator

smoothOsc() Built-in Study Functions

The Smoothed Oscillator displays the simple difference between two smoothed moving averages of a price. It can be used to help identify divergences, short-term variations from the long-term trend, and to identify the crossing of two smoothed moving averages, which occur when the oscillator crosses the zero line.

Syntax
smoothOsc( nFastLength, nSlowLength [, Series | sym() | inv() ][, nBarIndex ] )

Parameters
Parameter: Description: Default:
nFastLength Required. Number for the fast period length to use for the calculation.

 

n/a nSlowLength Required. Number for the slow period length to use for the 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.

 

Base sym/inv nBarIndex [Optional]  Bar index of series to retrieve.

 

n/a


Return Value(s)

Returns a Series Object when nBarIndex is not specified.

Returns a single value when nBarIndex is specified.

Code Examples
Single Line Indicator:
function main() {    return smoothOsc(5, 10);}

Single Line Study-on-Study Indicator:
function main() {    return smoothOsc(5, 10, hl2());}

Retrieve single values:
function main() {    var nValue_0 = smoothOsc(5, 10, 0);  // Current Bar Index    var nValue_1 = smoothOsc(5, 10, -1); // Prior Bar Index             return new Array(nValue_0, nValue_1);}

Initialize a Series Object:
var xStudy = null;function main() {    if (xStudy == null) {        xStudy = smoothOsc(5, 10);    }            // retrieve single values for conditional statements    var nValue_0 = xStudy.getValue(0);  // Current Bar Index value    var nValue_1 = xStudy.getValue(-1); // Prior Bar Index value            return nValue_0;  // Plot Current Bar Index Value}

Initialize a Series Object based on an external interval:
var xStudy = null;var bInit = false;  // Initialization flagfunction main() {    if (bInit == false) {        xStudy = smoothOsc(5, 10, inv(20));  // 20-min interval        bInit = true;    }            // retrieve single values for conditional statements    var nValue_0 = xStudy.getValue(0);  // Current Bar Index value    var nValue_1 = xStudy.getValue(-1); // Prior Bar Index value            return getSeries(xStudy);  // Synchronized Series plot}


Initialize a Series Object based on an external symbol and interval:
var xStudy = null;var bInit = false;  // Initialization flagfunction main() {    if (bInit == false) {        xStudy = smoothOsc(5, 10, sym("IBM,20"));  // IBM 20-min interval        bInit = true;    }         // retrieve single values for conditional statements    var nValue_0 = xStudy.getValue(0);  // Current Bar Index value    var nValue_1 = xStudy.getValue(-1); // Prior Bar Index value         return getSeries(xStudy);  // Synchronized Series plot}
