Instantiate indicator OnBarUpdate calling only a predifined number of bars

[vavatete]

Hello,

I need to run several interations of a indicator with parameters determined by logic OnBarUpdate.

Is there a way to run it only in the last bars for performance reasons?

I just know using Onrender() to draw object will faster a bit.

If it was logic flow, I think it should be stick to the OnBarUpdate there.

Thank you for your reply.

Is this case i'm not ploting, so OnRender should not be useful.

I just need to make several interactions with diferent indicator parameters in the last bars until a mach is found.

Thank you again!

Hello vavatete,

Thank you for the post.

You can call the indicator on a last bar to start calculating at that point for performance reasons however by not calling the indicator during historical bars it won't be able to calculate that data. For the indicator to calculate the full series of historical data points it would need to be called from OnBarUpdate during those bars.

I look forward to being of further assistance.
