Hello vinay,

Thank you for writing in.

Please note that while we do not provide programming services, this is a relatively simple indicator to program.

Please take a look at the following code below:

protected override void OnBarUpdate()
{
	if (Close[0] > EMA(8)[0] && Close[0] > EMA(21)[0])
		BarBrush = Brushes.Green;
	else if (Close[0] < EMA(8)[0] && Close[0] < EMA(21)[0])
		BarBrush = Brushes.Red;
	else
		BarBrush = Brushes.Blue;
}

For more information about BarBrush, please take a look at this help guide link: https://ninjatrader.com/support/help.../?barbrush.htm

Please, let us know if we may be of further assistance.

Thanks for this. Really appreciate this.

BarBrush

I am trying to reference a 5 minute bar's close to the previous bar's close in addition to comparing highs and lows. Below is what I have but it doesn't color any bars. Am I not referencing each bar's close, high and low correctly?

protected override void OnBarUpdate()
{
if (Close[0] > Close[1] && Low[0] < Low[1])
BarBrush = Brushes.Green;
else if (Close[0] < Close[1] && High[0] > High[1])
BarBrush = Brushes.Red;
else
BarBrush = Brushes.Black;
}

Hello josef,

Thanks for your post.

When you run your script, do you see any error messages listed in the "Log" tab of the NinjaTrader control center?

Based on what you are showing you may have an indexing error on the first bar loaded which you can prevent by placing this line ahead of your code in OnBarUpdate(): if (Currentbar < 1) return;

When I compile it I don't see any errors. Also, I can't find a "Log" tab. I'm using NT8. When I added your recommended code I do get the following error code: CS0103

Did I put it in the correct spot?

protected override void OnBarUpdate()
{
if (Currentbar < 1) return;
if (Close[0] > Close[1] && Low[0] < Low[1])
BarBrush = Brushes.Green;
else if (Close[0] < Close[1] && High[0] > High[1])
BarBrush = Brushes.Red;
else
BarBrush = Brushes.Black;
}

Hello josef,

Thanks for your reply.

In the NinjaTrader8 control center, the tabs are located at the bottom of the control center. Typically you will have "Orders", "Executions", "Strategies", "Positions", "Accounts", "Log" and "+". If you do not see "Log" then click the "+ " and select Log.


In the code I provided there was a typo, here is the correctly capitalized version:

if (CurrentBar < 1) return;
