I would like to find the minimum value of the MACD Histogram over the last 10 days and perform an operation on it.

Obviously I can get the MACD histogram bar values, either using the MACD indicator or calculating it directly in a custom PCF. But how can I determine what the minimum value is for the time period involved?

Unlike other indicators that have their own PCF code “operators” (BOP, STOC, TSV) I am not aware of a MACD operator that I could hook up with the MIN operator [for instance,

Min(MACD12.26.9,10).]

Perhaps it exists and I just haven’t found it?

I looked into Change Data Source, but I don’t see any “minimum” indicator (say, for Price [c]) which I could then “redirect” and then assign to another indicator.

Is there a reserved-name for a “generic” variable that I can use in a PCF (say, “DataSourceRangeVariable”) that I could use as the basis for my mathematical operation, which then would take on the value of the selected Data Source variable? So, I could write PCFs that calculate:

DataSourceRangeVariable * 10,

Or

DataSourceRangeVariable.5 / c

Or

Avg(DataSourceRangeVariable.2,12) - Avg(DataSourceRangeVariable.2,26)

…and then change the data source to MACD Histogram ##.##.## (I think you can see the direction I am heading in…)

Other than creating a mile-long formula to check bar 0 with bars 1-9, bar 1 with bar 0 and bars 2-9, bar 2 with bars 0-1 and bars 3-9 is there any way to do this?

You could add Donchian Channels to the MACD with the Period set to 10 and the Offset set to 0. The lower Donchian Channel would then be the value of interest. With a few exceptions, it would not be possible to use the result in calculations however.

The other option would be to use the techniques given in the Min Max PCFs topic. The resulting formula would be rather long however.
