Compare ATR and Range

[kadan]

Hello,

I am trying to have a simple indicator which will highligh bar in chart if the bar´s range is bigger than multiple of ATR.

I have created this simple code:

protected override void OnBarUpdate()
{
double myATR = ATR (14)[1];
double myRange = Range () [0];

if ( myRange > (1.35*myATR))

{
DrawDiamond("tag1", true, 0, Low[0] - TickSize, Color.Black);
}

else
{
}

However nothing is drawn in the chart. Could you kindly point out where did I make a mistake?

Thank you.

Hello kadan, and thank you for your question.

The documentation for Range() ,

http://ninjatrader.com/support/helpGuides/nt7/range.htm

does not mention whether this Range is a True Range or not. This would have to be a True Range in order to compare it to an Average True Range. However, the documentation does contain a code example in which an Average Range is generated. That is (modified to fit your use case of a 14-period average),

[FONT=Courier New]SMA(Range(), 14)[0][/FONT]

I would therefore recommend changing

[FONT=Courier New]double myATR = ATR(14)[1];[/FONT]

to

[FONT=Courier New]double myAR = SMA(Range(), 14)[1];[/FONT]

Beyond this, I would highly recommend using the Print() command to display the values of either your ATR or AR alongside your Range output, so that you can see visually what is occurring.

Finally, if none of the above has helped, I would highly recommend commenting out all conditional logic, and simply calling DrawDiamond unconditionally, then comparing to the help guide documentation here,

Please let us know if there are any other ways we can help.

The first place to look is in your log, for logged errors. In your case, it is because that line is trying to access bars that do not yet exist at the time.
