About coding an indicator on indicator

[MickeyHR]

Hello
I would like to calculate an indicator on indicator rocoflinreg (ROC by 3 days of LinReg by 5 days) with changeable variables and I have a couple of questions

// In ninjascript    
#region Variables     
private int       period=5;     
private int       [COLOR=Red]rocperiod[/COLOR]=3;  
// Question 1) I guess I need to add [COLOR=Red]rocperiod[/COLOR] as Variable like above? 
//...
/// <summary> 
/// Called on each bar update event (incoming tick)
/// </summary>    protected override void OnBarUpdate()     
{            
double [COLOR=SeaGreen]rocoflinreg[/COLOR] = ROC(LinReg(), period)[0];  
// Question 2) Where above should I add the [COLOR=Red]rocperiod[/COLOR] variable?

Thank you

Hello,

I imagine you'd want :

ROC(LinReg(), rocperiod)[0];
