Hi Bruce,

I am trying to create a histogram showing the difference of Hull MA 30 - Hull MA 30 of previous day,

so to see the slope of the MA.

Something similar of what I could do with Exp MA with: XAVGC30-XAVGC30.1

thanks

Andrea

If you need an Indicator Formula then you could use the following.

(1725 * C + 1245 * C1 + 792 * C2 + 366 * C3 - 33 * C4 - 4455 * AVGC11.5 - 250 * C16 - 126 * C17 - 33 * C18 + 29 * C19 + 660 * AVGC11.20 + 40 * C31 + 24 * C32 + 12 * C33 + 4 * C34) / 27900

But you could also add a plain 1 period Rate of Change indicator to the chart (not %), set it to use the Histogram Plot Style and change its Data Source to use the Hull Moving Average plotted on the chart.

Thanks a lot 

You're welcome.
