can someone suggest what I'm doing wrong?

Hello,

Below is the code for an indicator which plots the volume histogram with a dot that projects end of bar volume. It compiles ok, but when I add it to a chart all I get is the pane. No volume and no indicator. I used the NT help file tutorial as a guide, I'm very new at this. Any ideas?

///<summary>
/// This method is used to configure the indicator and is called once before any bar data is loaded.
///</summary>
protectedoverridevoid Initialize()
{

Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Dot, "PRV"));
CalculateOnBarClose = false;
Overlay = false;
PriceTypeSupported = false;
}
///<summary>
/// Called on each bar update event (incoming tick)
///</summary>
protectedoverridevoid OnBarUpdate()
{
// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.


double perCom = Bars.PercentComplete;
double volPRV = (1/perCom)*(Volume[0]);
PRV.Set(volPRV);
}

Please check the Log tab, likely an error on this indicator at runtime.

Nothing on Log tab, just the usual connection messages. Thank your for your help.

I just noticed that in the data window, the Volume field says "InfinityM".

Then your indicator values are infinite values. You will need to recheck your math.

OK, I started the whole thing over from scratch and played aroung with commenting out various portions to see what works and what doesn't.

Every clue I get suggests I'm using Bars.PercentComplete in an incorrect manner.

I assume, for example, on a 5 min chart that Bars.PercentComplete will return a value of 0.2 one minute into the bar, etc. Even if I just get rid of all my math and try and plot Bars.PercentComplete I get a nonsensical display.

I think the issue is that Bars.PercentComplete is returning a value of zero on historical bars. Might screw up your math? It should return a value of 1 on a historical bar. Either way, you should ensure that you are handling any potential divide by zero issues.

Ray,

I think I figured it out, but won't know until market opens tomorrow so I can run it live. It seems as the Bars.PercentComplete does NOT return the % completed, but rather the % remaining. I'll post again if this turns out to be true. If not, than I'm really baffled, because once I made the adjustment for this, everything looked correct.

Thank you very much for your help.
