Kelner Bands Avg Tru Range

[bkelly]

Hi Anyone,

I'm not even a novice in programming, and I'm at a loss as to how to apply to a chart a study that I downloaded (Keltner) to my esignal library folder. Also how to change the parameters.

What I'm looking for is a Keltner Band study with a 7-period EMA with the upper and lower bands a distance of one Avg. true range.


I'm also looking for an RSI indicator of 5 periods with a 13 period EMA of that 5 period RSI.

I'm afraid the Wizard isn't helping much.

Mnay thanks.

This will do the same as keltner channels,you just have to change the period to your liking.

How to access efs studies... just right click on the advanced chart.

Category: Keltner
Description: Keltner study with a 20 period exponential moving average of the basis line and bands based on 2.5 * Average True Range.

Parameters: nInputLength: Default is 20 (number of periods for basis line)
nRangeFactor: Default is 2.5 (multiplier for the bands)

I would just like to clarify that Keltner bands do not include ATR for the bands, but rather an average of the High-Low range which I term as unmodified High-Low. It is Stoller with his STARC bands that introduced the use of ATR for the bands. However many people have merged the 2 and call anything with ATR as Keltner but it should be termed as Stoller.

If you want to see Stoller bands in action (which in this thread has been termed as Keltner) you can download a script as per the following link:-

If anyone is interested in exploring other bands such as Anderson, Bollinger, Headley, Keltner, Kirshenbaum & Stoller with a "twist" please have a look at the following thread:-
