Need black volume bar for doji bars

[streetffightingman]

can some one add that a doji bar (a price bar where it closes on its open) can have a black color for its volume bar?
right now all doji bars have a green volume bar

Hi, streetffightingman, thanks for your post.

For normal plotting, you can use the PlotBrushes array to change the color of a specific brush. e.g.

if(Open[0] == Close[0])
            {
                PlotBrushes[0][0] = Brushes.Black;
                PlotBrushes[1][0] = Brushes.Black;
            }
            else
            {
                PlotBrushes[0][0] = Brushes.LimeGreen;
                PlotBrushes[1][0] = Brushes.Red;
            }

Your code is using the OnRender Override, so you will need to change the DX brush being used when a Doji appears. You can get the open and close of a bar from OnRender with GetOpen() GetClose().

Please let me know if this does not resolve your inquiry.

The problem is I do not know how to code. If you could tell me where to copy and paste code into the editor I would be so grateful cause Im an idiot to code.

maybe it would be easier to change this indicator in NT8

Hello streetffightingman,

Thanks for your reply.

Even modifying a simple script involves a number of steps.

To get you going, as this was a simple modification, I've modified the VolumeUpDown indicator (Renamed as VolumeUpDownDoji) to meet your request. Please note that this is provided as a courtesy and that it is against our policy make custom modifications.

If in the future you have similar needs, we recommend that you either take the time to learn C#/Ninjascript or seek 3rd party programmer's to create what you need.

Here is a screenshot of the indicator comparing the standard Volume Up down with the VolumeUpDownDoji. Below the screenshot is a link to download the indicator.
