How to add an indicator to strategy without adding it to chart

[alex.nt]

Hi,

I can add an indicator to strategy (i.e. then using it in OnBarUpdate) like this:

// In Initialize()
MyIndicator m_indicator = MyIndicator(Parameter);
Add(m_indicator)

// in OnBarUpdate()
if (m_indicator.IndicatorValue[barsBack] > 0)
...

Assume now that I do not want my indicator to appear on the chart but I still would like to use it internally. How do I do that in the most efficient way?

Thank you!

Hi Alex, I guess I'm not exactly following you here - you would not have to Add the indicator in for display to use this efficient way of referencing it.

Please confirm that if I assign a reference to my m_indicator variable then the indicator will be accessible at any moment thereafter (in OnBarUpdate and so on).

Also, what exactly happens when we write MyIndicator m_indicator = MyIndicator(Parameter);?

I mean when the indicator's object is constructed and the like?

Alex, your understanding is correct.

Most of the background can be still found here from where ( I believe ) this technique originated sometime ago - http://web.archive.org/web/201004282...ds/rwt/rwt004/
