Volume Up / Down based on Close

[Richard168]

I'd like to change the VolumeUpDown indicator, which is based on comparing the current bar's open with the current bar's close, to comparing current bar's close and previous bar's close.

I thought it's a simple change:

protected override void OnBarUpdate()
{
if (Close[0] > Close[1]) // changed from: if (Close[0] >= Open[0])
{
Values[0].Set(Volume[0]);
Values[1].Reset();
}
else
{
Values[1].Set(Volume[0]);
Values[0].Reset();
}
}

I got a clean compile but no volume shows up. I don't understand why.

Please take a look and let me know I have done wrong.

Thanks,

Richard

Hi Richard168,

Check the log tab of control center for error messages. You're likely running into this issue here:

You can resolve by preventing script from accessing invalid values on the first bar in series.

if (CurrentBar < 1) return; //add to top line in OnBarUpdate().

I used the above quoted code too with the intention of having a green volume bar for an up bar and red volume bar for a down bar, however, I still didnt get any difference from the default indicator.

As you may know the default indicator doesnt only print up green bars and down red bars but sometimes also prints green down bars and red up bars.

Please help me with the changes I want.

Also if you know of a volume indicator doing what I want, please give me a link. I have searched but in vein

Hello ramos04,

Thank you for your post.

The VolumeUpDown should only plot green up and red down based on the default settings. Can you provide a screenshot of this not being the case?

What happens when you use the code from this thread? Can you provide a screenshot of this as well?

To send a screenshot with Windows 7 or newer I would recommend using Window's Snipping Tool.

Click here for instructions: http://windows.microsoft.com/en-us/w...#1TC=windows-8

Alternatively to send a screenshot press Alt + PRINT SCREEN to take a screenshot of the selected window. Then go to Start--> Accessories--> Paint, and press CTRL + V to paste the image. Lastly, save as a jpeg file and send the file as an attachment.

I look forward to your response.

Yes. Will be contacting you as directed.

Coming from a Meta Trader 4 (MT4) background, the volume there is calculated based on the volume close ie green for a volume bar that closes higher than the previous and red for a volume bar closing below the previous bar. This is not necessarily the case with the default VolumeUpDown NT7 indicator, and am also not knowledgeable enough to technically explain why it (VolumeUpDown) can print green up volume bars and green down volume bars and the same with red volume bars.

NinjaTrader_PatrickH developed me a VolumeUpDown2 and also allowed me to share it. It does what is described above that MT4 can do.

Enjoy
