The Price Oscillator displays the difference between two moving averages of a security's price. The difference between the moving averages can be expressed in either points or percentages.
Syntax
osc( nFastLength , nSlowLength , bExponential [, Series | sym() | inv() ][, nBarIndex ] )
Parameters
Parameter: Description: Default:
n/a nSlowLength Required. Number for the slow period length to use for the calculation.
n/a bExponential Required. Boolean true or false to use exponential calculations.
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.
n/a
Return Value(s)
Returns a Series Object when nBarIndex is not specified.Returns a single value when nBarIndex is specified.
Notes
Only available in versions 7.9 or later.
Code Examples
Single Line Indicator:
function main() { return new Array(osc(10, 21, false) );}
Single Line Study-on-Study Indicator:
function main() { return new Array(osc(10, 21, false, hl2()) );}
Retrieve single values:
function main() { var nValue_0 = osc(10, 21, false, 0); // Current Bar Index var nValue_1 = osc(10, 21, false, -1); // Prior Bar Index return new Array(nValue_0, nValue_1);}
Initialize Series Objects:
//global Series Object variablevar xStudy = null;function main() { if (xStudy == null) xStudy = osc(10, 21, false); // 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 // Plot Current Bar Index Value return nValue_0; }
Initialize a Series Object based on an external interval:
// global Series Object variablesvar xStudy = null;var bInit = false; // Initialization flagfunction main() { if (bInit == false) { xStudy = osc(10, 21, false, 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 // Synchronized Series plot return getSeries(xStudy); }
Initialize a Series Object based on an external symbol and interval:
// global Series Object variablesvar xStudy = null;var bInit = false; // Initialization flagfunction main() { if (bInit == false) { xStudy = osc(10, 21, false, 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 // Synchronized Series plot return getSeries(xStudy); }
