One website states "The average directional movement index rating (ADXR), was created by Wilder as a measuring tool for the strength of ADX. ADXR is the average of the current ADX and the ADX 14 days ago."
Yet another states "Average Directional Movement Rating quantifies momentum change in the ADX. It is calculated by adding two values of ADX (the current value and a value n periods back), then dividing by two."
So to make both work, I formulated ADXR as [(ADX(14) - ADX(14) 14 days ago) divided by 2]. This sounds too simplistic to be believed, but who knows?!

Neither of those calculation is quite right.
Essentially the ADXR is type of exponential/weighted moving average, not a straight average.
The first ADXR = Average(ADXes for the last 14 days).
Thereafter, the ADXR(today) = (ADXR(yesterday) + ADX(today))/2
Notice that the last calculation creates a kind of exponential average since the latest ADX is heavily weighted as 1/2 the new value, but the previous ones get divided by two for every calculation. That is the ADX of 1 day ago accounts for 1/4 of the new value, 2 days ago only account for a 1/8 of the value...ad infinitum
I got these calculations from the original book.
Now if you could help me calculate that, I would be very appreciative.

Niko.. did you mean
You subtracted in your filter but the notes said to ADD.
Nerriezohn:
The first ADXR = Average(ADXes for the last 14 days).
Thereafter, the ADXR(today) = (ADXR(yesterday) + ADX(today))/2
Above doesn't work!! Looks like "ad 1 day ago" can't be used in a SET statement!!
Have to settle for:
Download to spreadsheet and then do the math.
