using the ROC to determine the slope, i am trying to figure out the pcf for 

ROC(MACDH(19,39,12)) - ROC(MACDH(65,90,12))  

Where the ROC is averaged over 3, and MACDH is the MACD Histogram.

Can u pls help.

thx

I'm really not quite sure what is being asked. Do you want the 3 period simple moving average of the difference between the 1 period rate of change of the two MACD histograms, do you want the difference in the 3 period rate of change of the two MACD histograms or do you want something else entirely?

The Delta of  slopes of  2 MACD Histograms.

[Slope of MACD Histogram(19,39,12)]  -  [Slope of MACD Histogram(65,90,12)]

[Slope of MACD Histogram(19,39,12)] - [Slope of MACD Histogram(65,90,12)] can be done as the following as long as a 1 period net rate of change is being used for both histograms.

(1193931 * C - 5716700 * XAVGC12.1 + 5320458 * XAVGC19.1 - 689689 * XAVGC39.1 - 212940 * XAVGC65.1 + 104940 * XAVGC90.1) / 33857460

But where does the "ROC is averaged over 3" come into play?

Thought there would be a way to use  a expression using the ROC indicator to calc the slope

ROC(MACDH(19,3912))    -    ROC(MACDH(65,90,12)) 

There is no built in syntax for either ROC or MACD in the Personal Criteria Formula Language. You need to manually construct the both using the syntax which is available.
