Hi Bruce,

I'd like to revisit this topic, which is related to another one, "ADX" by user 'opterat' (April 20, 2009).

The famous technician Chuck LeBeau captures my issues succintly in this short article: www.tradingmarkets.com/.site/stocks/how_to/articles/-76480.cfm 

There are two questions:

1. Interpretation of the slope of ADX is at least as important as the actual ADX value. Is there any way to calculate slope in TC2000? (I've also tried to get the slope for a Linear Regression line over 20 bars... any chance there?)

2. Rounding in the Worden ADX indicator calculation. You mentioned to 'opterat' that even TC2000 rounds numbers going into the formula for ADX. According to LeBeau, this can render any measure of slope invalid. When he wrote that article, back in 2010, he said he was trying to get chart providers like Worden to use at least 2 decimals. Has Worden mended its ways and fixed the ADX calculation since you wrote back to 'opterat' back in April 2009? 

Thanks once again.

A Condition Formula for a 20-Period Linear Regression Slope can be written as:

Using Linear Regression vs Classical Peaks/Valleys for Divergence Analysis

(9.5 * C + 8.5 * C1 + 7.5 * C2 + 6.5 * C3 + 5.5 * C4 + 4.5 * C5 + 3.5 * C6 + 2.5 * C7 + 1.5 * C8 + .5 * C9 - .5 * C10 - 1.5 * C11 - 2.5 * C12 - 3.5 * C13 - 4.5 * C14 - 5.5 * C15 - 6.5 * C16 - 7.5 * C17 - 8.5 * C18 - 9.5 * C19) / 665

I prefer an unrounded ADX as well. TC2000 rounds the ADX but does not round the AXDR (although it is based off of a rounded ADX), +DI and -DI. Note that there is actually little question as to which is correct however. Wilder invented ADX and the calculations specified use rounding. I don't know why we would round ADX, but not the the other values.

I cannot think of a way to calculate a slope of ADX in TC2000. It is possible to calculate the slope of ADX in StockFinder (and you can also create a version of ADX that is not rounded).

Thanks, Bruce. 

WRT rounding of the ADX, apparently Wilder did it with rounding to simplify calculations in the days before we all had capable computers. Now, though, there's widespread agreement that the inputs should not be rounded. I understand that many chart providers have fixed it to calculate to 2 or 3 decimals. Surely, the hotshots at Worden can upgrade your ADX before lunch!

As for Doing-It-All in Stockfinder... yup, we TC2000 users have long wondered when we'd get a Back To the Future experience of RealCode. I know it's on the Wish List and will try to be patient.

Thank you for your suggestion. It has been assigned case number 10757.
