help needed on ratio of two MAs (one with offset)

[bf2]

Can someone please help me with this indicator?

I need the ratio of two moving averages plotted as graph in a separate window.

The first MA is a 20-sma.
The second MA is a 20-sma, but with an offset of -20, i.e. over close(-20) to close(-39).

How do I do this? I am having trouble creating the series.

Many thanks.

Hi,

If you do a search in the forum for "ratio of series" you will find a number of helpful posts. There even is an efs in the function library that will do this for you.

To offset a series use offsetSeries().

Hope this helps.
