Indicator no longer working

[Mindset]

I have an indicator that measures bar duration (in seconds only,not minutes and seconds)
It stopped working today. Any ideas?
It still compiles I just get an empty panel.

protected override void OnBarUpdate()
{
		
if(CurrentBar < 3)
return;
		
bartimespan = Bars.GetTime(CurrentBar) - Bars.GetTime(CurrentBar -1); 

n2 = Convert.ToInt32(bartimespan.Seconds);
n3 = Convert.ToInt32(bartimespan.Minutes*60);
					
spanseries.Set(n2+n3);
		
RangeTimeEMA.Set(EMA(spanseries,21)[0]);
string avg = String.Format("{0:N0}",spanseries[1]);
Plot0.Set(Math.Min((spanseries)[0],600));
DrawTextFixed("BottomRight", "Current\n" +spanseries[0]+"\nPrior \n"+spanseries[3]+"," + spanseries[2]+"," + spanseries[1],
		TextPosition.BottomRight,Color.White,ChartControl.Font,Color.Black,Color.Blue,10);
}

Hi Mindset,

At a glance I don't see anything obvious, however, I would certainly check the Log tab for any errors.

From there, try using Print() statements to figure out which parts/calculations are going awry.

Doh!

The error seems to be in the line

RangeTimeEMA.Set((EMA(spanseries,21)[0]

I amended another line to
if(CurrentBar < 25 )
return;

I can see that spanseries doesn't have 21 nos to average, how do I get around that?

Hi Mindset,

Try moving your CurrentBar check to the line just before...

RangeTimeEMA.Set(EMA(spanseries,21)[0]);

That way the values are calculated before you try to access them 21 bars back.

[Mindset]

Current Bar

CurrentBar check is first line of OnBarUpdate.
if I comment out the rangetimeema line it works (minus the ema line of course).
If the line is in it compiles but no output.

Hi Mindset,

Have you tried adding the second CurrentBar check?

protected override void OnBarUpdate()
{
		
if(CurrentBar < 3)
return;
		
bartimespan = Bars.GetTime(CurrentBar) - Bars.GetTime(CurrentBar -1); 

n2 = Convert.ToInt32(bartimespan.Seconds);
n3 = Convert.ToInt32(bartimespan.Minutes*60);
					
spanseries.Set(n2+n3);

if(CurrentBar < 25 )
return;		

RangeTimeEMA.Set(EMA(spanseries,21)[0]);
string avg = String.Format("{0:N0}",spanseries[1]);
Plot0.Set(Math.Min((spanseries)[0],600));
DrawTextFixed("BottomRight", "Current\n" +spanseries[0]+"\nPrior \n"+spanseries[3]+"," + spanseries[2]+"," + spanseries[1],
		TextPosition.BottomRight,Color.White,ChartControl.Font,Color.Black,Color.Blue,10);
}

[Mindset]

Tried that

Doesn't work.
Let me think on this - I am sure it is simple to resolve.

Hi Mindset,

To clarify, is the text not showing at all? One of the plots?

Are you still getting errors in the Log? What errors?

[Mindset]

Error

I am getting an index outside bounds of array error. And neither plot shows.
If I comment out the rangetimeema I get the first plot but not the second.

MindSet, are you working on 65 or 7 beta with this indicator? Would you mind attaching the full cs / zip for us to test? On NT7 the dataseries handling slighly changed and all points would need a setting of value otherwise you could run into those exceptions like you've seen. Thanks.

[Mindset]

Zip

Hi Bertrand

7b15.

I have another issue in that I can't export from NT7 currently ( related issue?)

so here is a cs version that you can test.

Hi Mindset,

Looking at your code, it seems you do not have a plot for "RangeTimeEMA"

Adding...

Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "RangeTimeEMA"));

to Initialize() solved this on my end.

As for exporting, what issue are you experiencing?

[Mindset]

lol

That's hilarious - well done,Tim. A real Homer moment. I am fascinated that it worked for 3 days without that line??
The other issue I am dealing with support already - I suspect a reinstall is due.
:-(
