Trying to modify Range Indicator to display Today Current Close minus Yesterday Close

[tuanly]

Hello,

I am trying to modify the built in Range Indicator for use on daily bar where it would display the difference between the current close and yesterday close instead of today high minus today low.

I tried the following simple modification but it doesn't work.

Value.Set(Close[0] - Close[1]);

Thanks

Hello tuanly,

Thank you for your post and welcome to the NinjaTrader Support Forum!

Have you tried setting the CalculateOnBarClose to False?

Hi Patrick,

Thanks for the quick reply.

I tried it with CalculateOnBarClose = false and nothing still happens

This is my code:

protected override void Initialize()
{
CalculateOnBarClose = false;
Add(new Plot(Color.Firebrick, PlotStyle.Bar, "Close2Close"));
}

/// <summary>
/// Called on each bar update event (incoming tick)
/// </summary>
protected override void OnBarUpdate()
{

Value.Set(Close[0] - Close[1]);

}

I checked by seeing if it worked by changing the code to Value.Set(Close[0] - Open[0]); and it does. So im guessing there must be something missing regarding pulling yesterday close?

Hi Patrick,

Their is an error, here is the log message.

Error on calling 'OnBarUpdate' method for indicator 'Close2Close' 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.

What is the error in your log?

I expect it to say: "You are accessing an index with a value that is invalid since its out of range", in which case you need to escape your first bar.

In which case, I would suggest that you look at my response in this tread.
