Choppy Market Index

[pandyav]

I am trying to develop a very simple indicator called Choppy Market Index.

The Choppy Market Index (CMI) is an indicator which compares the difference between the close of the current period with the close X periods ago and normalizes this against the range (highest – lowest) of that period. The value of the indicator is finally multiplied by 100 to give a number between 0 and 100. The formula of the indicator is highlighted below :


CMI = ((|Close Current period – Close X periods in the past|)/(Highest point in X periods – Lowest point in X periods))*100


Following is my code for NT but for some reason I am not able to see any line or result. Can someone please tell me what am I doing wrong here?

protected override void OnBarUpdate()
{

Value.Set(((Math.Abs(Close[0]-Close[50]))/(MAX(50)[0]-MIN(50)[0]))*100);
}

Thanks

Hello,

You're likely running into an issue explained in the following forum post from our Tips section:

http://www.ninjatrader.com/support/forum/showthread.php?t=3170

Please try adding the following snippet to the beginning of your code in OnBarUpdate()

if (Current Bar < 50)
return;

You need to ensure you have enough bars on the chart to calculate correctly. This should ensure your Close[50] will calculate.


It is always good practice to watch the Log tab of the Control Center went developing new indicators to check for any errors.
