Bollinger on OBV ?

[T2020]

Shouldn't something like this work . A minor change to the original Bollinger
indicator to make bands of OBV ?
Value.Set(OBV(SMA(Period))[0] + NumStdDev * StdDev(Period)[0]); Value.Set(OBV(SMA(Period))[0]);
Value.Set(OBV(SMA(Period))[0] - NumStdDev * StdDev(Period)[0]);

Would imagine you would get something plotted out of that, but you can't just use Value.Set for all 3. Value is a single plot. Going .Set 3 different times is just going to overwrite prior .Set calls.

Changed to Upper.set and Lower.set ,but didn't make any difference . With
my limited knowledge , all I can do is try to edit existing indicators ,if it
doesn't work .... I don't see any real complete tutorials how to do this on your
own .

T2020,

You can't just change the names to different plots. You actually have to have a plot named those names. Please ensure in the Properties region there actually are plots with those names.

[T2020]

You mean some thing like this ?

#region Properties
/// <summary>
/// Gets the lower value.
/// </summary>
[Browsable(false)]
[XmlIgnore()]
public DataSeries Lower
{
get { return Values[2]; }

I'm just trying to modify the standard " Bollinger " indicator . Your right I get
something to plot in a lower pane , but it's a long way away from OBV .

You will need to debug your values. Whatever value you set is the value that will be plotted. If those values just don't make sense in relation to OBV then you will have to adjust the logic you are using to generate those values.

I think your trying to help and I am trying to learn more , but I have no clue
what that means . Yes there's obviously some logic off some where . The
snap shot looks like it should work to me . ???

Take those lines and do a Print of the value.

Print(OBV(SMA)Period .....);
Print(..whatever value you need printed..);

Then you will be able to understand why your indicator plots where it does.

Well , looked all over Ninja and help files trying figure out what that was ?

Not following you. Just use the Print() method to print whatever you want printed. Print the values so you can see what the values are and evaluate it by hand. Prints go to the Output Window.

OK , I thought maybe you were talking about some special analysis app in
Ninja ...... . Still , forgive my ignorance but "Print() method" ? Not seeing
anyway to get something to the output window . And where
are these values suppose to come from ? I feel like I'm being sent on a wild
goose chase .

T2020,

Just place these lines above your .Set lines. Then run your indicator with the Output Window open and you will get the print out of the values as your indicator processes them.

OK , now this is starting to make some sense . The Output values are way
off . The Orange line ...should mimic ... the Blue line below . So , whats next ?
Not sure how this tells me what correction I should make . How the Code should be changed ?

T2020, make sure you're printing out exactly what you want to. Here you can see exactly how the values are being set:

protected override void OnBarUpdate()
        {
            Print("");
            Print("Bar:\t" + CurrentBar);
             
            Print("OBV(SMA(Period))[0]=\t\t" + OBV(SMA(Period))[0]);
            Print("NumStdDev * StdDev(Period)[0]=\t" + NumStdDev * StdDev(Period)[0]);

            Upper.Set(OBV(SMA(Period))[0] + NumStdDev * StdDev(Period)[0]);
            Print("Upper set at:\t" + Upper[0]);
            
            Middle.Set(OBV(SMA(Period))[0]);
            Print("Middle set at:\t" + Middle[0]);
            
            Lower.Set(OBV(SMA(Period))[0] - NumStdDev * StdDev(Period)[0]);
            Print("Lower set at:\t" + Lower[0]);
        }

[T2020]

That is more detailed . All the numbers are positive on the output window and
OBV itself is a very negative number on this chart . Seems to me that :

Middle.Set(OBV(SMA(Period))[0]);
Should be :
Middle.Set(SMA(OBV(Period))[0]);

But that won't compile . So , ???
