New Basic Indicator converted from Strategy

[ij001]

Hi there,

I have simple bits of code that I created a strategy with. It compiles & works as planned. I learned with templates that it would be better suited as an indicator like a moving average so I copied the code and made it an indicator.

The indicator was working earlier this week during market hours but now for some reason isn't. However the other predefined indicators are (MA, etc.)

There is no "Enable = True" with indicators so I can't figure out what could be the issue?
Something in Data Series?

Attached is a screenshot of the indicator properties.

The indicator's properties do not tell much. You may want to post any errors in the log instead.

ij001, as koganam has said, can you please post the error messages you're receiving in the logs (right-most tab of Control Center)? You could also post the code if you want.

There was something in the log:

Error on calling 'OnBarUpdate' method for indicator 'NR7' on bar 0: You are accessing an index with a value that is invalid since its out of range. I.E. accessing a series [barsAgo] with a value of 5 when there are only 4 bars on the chart.

The code is for a 'NR7':

protected override void Initialize()
{
Overlay = true;
CalculateOnBarClose = true;
}

protected override void OnBarUpdate()
{

if (

Math.Abs(High[0]-Low[0]) <= Math.Abs(High[1]-Low[1]) &&
Math.Abs(High[0]-Low[0]) <= Math.Abs(High[2]-Low[2]) &&

Math.Abs(High[0]-Low[0]) <= Math.Abs(High[3]-Low[3]) &&

Math.Abs(High[0]-Low[0]) <= Math.Abs(High[4]-Low[4]) &&

Math.Abs(High[0]-Low[0]) <= Math.Abs(High[5]-Low[5]) &&

Math.Abs(High[0]-Low[0]) <= Math.Abs(High[6]-Low[6]) &&

Math.Abs(High[0]-Low[0]) <= Math.Abs(High[7]-Low[7])
)
BarColor = Color.Purple;

}

}

You are trying to process bars that do not yet exist. The simplest solution is to escape the initial bars thus:

protected override void OnBarUpdate()
{
[COLOR="Red"]if (CurrentBar < 7) return;[/COLOR]
if ( ...
