Hi Bruce,

Based on this article by technical guru Chuck LeBeau...

...I'd like to find the rate of adcvance/decline in the ADX. For example, if today’s ADX is 25.00 and yesterday’s ADX was 24.00, then the rate of advance is 1.00. LeBeau’s lesson is that the actual value of the ADX doesn’ t matter so much as the direction and rate of change.

Using Mac version 12.5, we can't use "ADX" in a PCF. (It looks as though this is possible in the Windows version 17.)

Way back in 2006 and again in 2009, you responded to questions about the ADX formula saying it was impractically long and couldn't be used in a PCF.  Is that still the case with 12.5?

Thanks!

ADX is on the list with Version 17

On version 17, yes. But not on version 12.5, where Mac users have been stuck for about 3 years.

We can plot ADX as an indicator, but cannot plug it in to PCFs. So, I'm asking whether the raw ADX formula (default 14,14 parameters) is available to paste into a PCF and whether it's practical in terms of processing time.

ADX is not available as part of the Personal Criteria Formula Language in TC2000 v12.5. It is only available in TC2000 v17+.

That said, you can add both the ADX and Rate of Change indicators to the chart and change the data source of the ROC indicator to use ADX instead of price history.

Thanks, Bruce. The ROC works!

You're welcome.
