Indicator code placement

[JTizz]

I am trying to add bar brushes to an indicator.
Where, at what number line would I place the brush code?

Picture on left, bar brush is what I want to add to indicator on right. Any info would be helpful. Thx

Bottom picture is the indicator and top is the bar brush i want to add to it.

I probabally needed to put this question in indicator development not strategies.

Hello JTizz,

Thank you for your post.

I have moved this thread to Indicator Developement.

Where you use BarBrush in your code would depend on what you are trying to accomplish. If you would like to change the BarBrush color when a certain condition happens, you would need to create that condition followed by calling BarBrush.

See the attached example script which demonstrates using BarBrush to change the color of a bar when a certain condition happens.

Also, see this help guide link for more information.

I looked at the links you have provided...Thx Here is what I want to add to the above indicator. Where would it be added to the indicator? What line number?

Hello JTizz,

Our role is not really to advise on "copy this code and paste it here" so much as it is to support our product and provide direction for accomplishing your tasks.

Changing the BarBrush property will require that you understand how the BarBrush property can be used and a will also involve basic understanding of C# syntax. You will need to know what exactly you will want to check to create your condition to then set BarBrush.

Please observe that in the strategy code, the indicator plots are referenced as DynamicSR.Resistance[0] and DynamicSR.Support[0]. Within the indicator, you would not reference those plots as DynamicSR.Resistance[0] and DynamicSR.Support[0], because you are already in the indicator. You could just reference Support[0] and Resistance[0] after they have been set.

We look forward to assisting.

This code is in strategy builder strategy. How can I convert code from Strat builder srtategy to an custom indicator?

[JTizz]

I am trying to have the Dynamic SR indicator that you created, paint the bars above the upper band the upper band color, bars below the lower band the lower band color and bars inbetween the bands a neutral color.

Hello JTizz,

Thank you for your note.

If you are wanting to create a modified version of the DynamicSR indicator, you could download and import the DynamicSR indicator followed by modifying the indicator in a New > NinjaScript Editor window. To do so, you would open a New > NinjaScript Editor window, double-click the Indicators folder, then select the DynamicSR indicator. Right-click in the indicator's code and click 'Save as' to create a copy of the DynamicSR indicator.

After creating a copy of the DynamicSR indicator, you would create conditions in your script that check if the current Close[0] is greater than or less than the Support[0]/Resistance[0] plot and call BarBrush to change the color of a bar when that condition becomes true.

That being said, you would create your conditions in the OnBarUpdate() method of the script. Something you could do is check if the current Close[0] is greater than the Resistance[0] plot and call BarBrush to change the color of the bar to blue. The code would look something like this.

protected override void OnBarUpdate()
{
    if (Close[0] > Resistance[0])
        BarBrush = Brushes.Blue;
}

This would also need to be done for the Support[0] plot to change the bar color to magenta when the current Close[0] is less than the Support[0] plot.

I added the code as you described and everything compiled but as an indicator it does not plot on my chart. Any suggestions would be helpful. thhx

Hello JTizz,

I would suggest starting with a simple indicator that changes BarBrush to get acquainted using this property.

For example, you can start with the following in a new indicator.

protected override void OnBarUpdate()
{
    if (Close[0] > Open[0])
        BarBrush = Brushes.Orange;
    else if (Close[0] < Open[0])
        BarBrush = Brushes.Purple;
}

After you are familiar using that code implement it in the custom indicator you want to modify and make sure it still sets the bar color.

Then, instead of checking Open vs. Close, use the Support and Resistance Series and compare that with the close price of the bar.

Debugging prints may be used to print out the values used in the conditions so you may see why the condition is/is not becoming true and allowing BarBrush to bet set. The prints may be viewed in a NinjaScript Output Window.
