Kaufman's Efficiency Ratio
I've attached an indicator for K-Efficiency that can be used as a trend strength indicator. Unfortunately, it currently has a bug. It compiles fine, but doesn't plot anything. I've gone over the math a bunch of times and haven't been able to find my error. I figured I would put it out to the community where there are a bunch of smart people who may have a few moments to help out. I also included the original code from TS commented out as a reference.Tags: None

Learning1,
You should always check the Control Center Log tab for errors. You will likely see "index out of range" exceptions since you are accessing Input[1] on the first bar of the chart where [1] 1 bar ago does not yet exist.
Add something like:
if (CurrentBar < 1)
return;
as the first line of the OnBarUpdate() method.RayNinjaTrader Customer Service

Undated and fixed
Thanks Ray, that was exactly the issue. Also thanks for the log advice - it will come in handy as my education continues.
Here is the updated indicator for the community.Attached Files
