Hello,

The basic concept is pretty straightforward. You would mostly just be using a  number of Cross functions and averages.

MetaStock's Cross function determines it's cross direction based on the order of the items inside the parentheses: Cross(UpValue,DownValue). The general logic would be as follows:

Cross((ShortMA+LongMA)/2,MajorMA) AND Cross(C,SAR(0.02,0.20))

This is not exact code. However you are defining the Hull Moving Averages would also need to be written out (potentially as variables) where ShortMA, LongMA, and MajorMA are listed. The other cross direction would simply take reversing the items listed within the functions:

Cross(MajorMA,(ShortMA+LongMA)/2) AND Cross(SAR(0.02,0.20),C)
