Hi,

Is there a way to convert the TC2000 code into thinkscript for the Kaufman Efficiency Ratio?  The scale range is from -100 to +100.  Thanks.

Here is the info on it from TC2000

Before getting started. I see you posted this in the "Alerts and Notifications" topic. However you did not provide any parameters for using this as an alert. So I believe what you are asking for here is a chart study. Please confirm, and I will move this post into the correct topic if needed.

From the example given in the link provided:

A 20 period Kaufman Efficiency Ratio can be written as follows.

100 * (C - C20) / SUM(ABS(C - C1), 20)

Directly translated into Thinkorswim also including a user input for length:

declare lower;
input length = 20;
plot ker = 100 * (close - close[length]) / Sum(AbsValue(close - close[1]), length);
