Min/Max Values of Painted DataSeries

[Zeos6]

Hi,

Does anyone know whether it is possible to get the min or max values of an entire data series painted on the chart? Specifically, I'd like to get the highest high, of all the bars painted, and if at all possible I'd like to get it done in OnStartUp() method. I have tried using MAX but during OnStartUp() the last bar painted does not seem to yet exist.Thanks for any input.

It would not be possible to gather this information OnStartUp() as this is only ran on the first bar on the chart (current bar = 0)

You will need to run this OnBarUpdate()

			int period = Count;
			
			double highest = MAX(High, period)[0];
			double lowest  = MIN(Low, period)[0];				
			
			Print(highest);
			Print(lowest);

Thanks Mathew. So if OnStartUP() runs only on the first bar, how can I access the entire data series painted on the chart without walking through it bar by bar? Or do I have to walk through bar by bar? I really want to know the highest High of the entire series and then scale on the basis of this highest High.

You will have to walk through Bar by Bar via the OnBarUpdate method.

Ok Thank you. Finally, as I walk through, bar by bar, how do I loop back to rescal starting at bar 1?

You can use a for loop to loop back through the data series.

What exactly are you looking to scale?

Thank you. I am trying to reset the Min/Max values on an indicator in another panel. Seems a waste to loop throug twice.
